99-679: Established in 1949 as the Dunwich Laboratory, the station was a facility established by the Queensland government. It was designed to encourage use and shared research between CSIRO fisheries division, the Queensland Department of Harbours and Marine (Fisheries) and the University of Queensland . It was initially run by CSIRO staff, in particular, Dr J.M. Thomson who lived on site from 1949 to 1953. The station

198-450: A captive portal webpage for access. Organizations, enthusiasts, authorities and businesses , such as airports, hotels, and restaurants, often provide free or paid-use hotspots to attract customers, to provide services to promote business in selected areas. Routers often incorporate a digital subscriber line modem or a cable modem and a Wi-Fi access point, are frequently set up in homes and other buildings, to provide Internet access for

297-647: A Wi-Fi network. Wi-Fi uses a large number of patents held by many different organizations. Australia, the United States and the Netherlands simultaneously claim the invention of Wi-Fi, and a consensus has not been reached globally. In 2009, the Australian CSIRO was awarded $ 200 million after a patent settlement with 14 technology companies, with a further $ 220 million awarded in 2012 after legal proceedings with 23 companies. In 2016,

396-447: A city-wide campaign to convert old phone booths into digital kiosks in 2014. The project, titled LinkNYC , has created a network of kiosks that serve as public Wi-Fi hotspots, high-definition screens and landlines . Installation of the screens began in late 2015. The city government plans to implement more than seven thousand kiosks over time, eventually making LinkNYC the largest and fastest public, government-operated Wi-Fi network in

495-475: A coherent set of statements criticising emissions trading without any additional wording needed. In subsequent Senate Estimates hearings during 2010, Senator Carr and Clark went on record claiming the paper was originally stopped from publication solely due to its low quality not meeting CSIRO standards. At the time of its attempted suppression, the paper had been accepted for publication in an academic journal, New Political Economy , which in 2010 had been ranked by

594-460: A common Wi-Fi version. The versions differ between the radio wavebands they operate on, the radio bandwidth they occupy, the maximum data rates they can support and other details. Some versions permit the use of multiple antennas, which permits greater speeds as well as reduced interference. Historically, the equipment listed the versions of Wi-Fi supported using the name of the IEEE standards. In 2018,

693-407: A computer and an interface controller is called a station . Stations are identified by one or more MAC addresses . Wi-Fi nodes often operate in infrastructure mode in which all communications go through a base station. Ad hoc mode refers to devices communicating directly with each other, without communicating with an access point. A service set is the set of all the devices associated with

792-604: A core aim of CSIRO is Cooperative Research "working hand in hand with industry [to] build partnerships and engage with industry to generate impact". On 25 November 2009, a debate was held in the Australian Senate concerning the alleged involvement of the CSIRO and the Labor government in censorship. The debate was called for by opposition parties after evidence came to light that a paper critical of carbon emissions trading

891-550: A founding member of the Wi-Fi Alliance, the term Wi-Fi was chosen from a list of ten names that Interbrand proposed. Interbrand also created the Wi-Fi logo . The yin-yang Wi-Fi logo indicates the certification of a product for interoperability . The name is often written as WiFi , Wifi , or wifi , but these are not approved by the Wi-Fi Alliance. The name Wi-Fi is not short-form for 'Wireless Fidelity', although

990-641: A greater degree by common building materials than the 2.4 GHz bands and usually give a shorter range. As 802.11 specifications evolved to support higher throughput, the protocols have become much more efficient in their bandwidth use. Additionally, they have gained the ability to aggregate channels together to gain still more throughput where the bandwidth for additional channels is available. 802.11n allows for double radio spectrum bandwidth (40 MHz) per channel compared to 802.11a or 802.11g (20 MHz). 802.11n can be set to limit itself to 20 MHz bandwidth to prevent interference in dense communities. In

However, the code sold to Novartis for more than A$ 2M was apparently not unique, and was based on a "cheap tracer ... bought in bulk from a Chinese distributor". Novartis was contractually bound not to reverse-engineer the tracer to verify its uniqueness. The Sydney Morning Herald report alleges that this

1287-991: A microwave internet link. The improved boating and diving facilities would attract scientists and researchers from all over the world. The new Moreton Bay Research Station and Study Centre (MBRS) was opened on 23 June 2000, by the Honourable Peter Beattie , MLA, with funding provided by the University of Queensland, the Port of Brisbane Corporation, the Royal Queensland Yacht Squadron and Consolidated Rutile Limited (now Sibelco Australia). 27°29′48″S 153°24′00″E  /  27.49667°S 153.40000°E  / -27.49667; 153.40000 Commonwealth Scientific and Industrial Research Organisation The Commonwealth Scientific and Industrial Research Organisation ( CSIRO )

1386-426: A particular Wi-Fi network. Devices in a service set need not be on the same wavebands or channels. A service set can be local, independent, extended, mesh, or a combination. Each service set has an associated identifier, a 32-byte service set identifier (SSID), which identifies the network. The SSID is configured within the devices that are part of the network. A basic service set (BSS) is a group of stations that share

1485-488: A series of biological controls into Australia, such as the introduction of myxomatosis and rabbit calicivirus for the control of rabbit populations. CSIRO is governed by a board appointed by the Australian Government, currently chaired by Kathryn Fagg . There are eight directors inclusive of the chief executive, presently Doug Hilton , who are responsible for management of the organisation. CSIRO

1584-409: A shadowy organisation responsible for US consumers being compelled to make "a multimillion dollar donation" on the basis of a questionable patent claiming "decades old" technology. The resulting debate became so heated that the author was compelled to follow up with a defence of the original article. An alternative view was also published on The Register , challenging a number of the assertions made in

1683-410: A single carrier, whereas 802.11a, Wi-Fi 4, 5 and 6 use orthogonal frequency-division multiplexing . Channels are used half duplex and can be time-shared by multiple networks. Any packet sent by one computer is locally received by stations tuned to that channel, even if that information is intended for just one destination. Stations typically ignore information not addressed to them. The use of

1782-583: A team of scientists began working on wireless LAN technology. A prototype test bed for a wireless local area network (WLAN) was developed in 1992 by a team of researchers from the Radiophysics Division of the CSIRO (Commonwealth Scientific and Industrial Research Organisation) in Australia, led by John O'Sullivan . A patent for Wi Fi was lodged by the CSIRO in 1992 The first version of

1881-615: A wider channel for higher throughput. Countries apply their own regulations to the allowable channels, allowed users and maximum power levels within these frequency ranges. 802.11b/g/n can use the 2.4 GHz band, operating in the United States under FCC Part 15 rules and regulations. In this frequency band, equipment may occasionally suffer interference from microwave ovens, cordless telephones , USB 3.0 hubs, Bluetooth and other devices. Spectrum assignments and operational limitations are not consistent worldwide: Australia and Europe allow for an additional two channels (12, 13) beyond

1980-577: Is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves . These are the most widely used computer networks, used globally in home and small office networks to link devices and to provide Internet access with wireless routers and wireless access points in public places such as coffee shops, hotels, libraries, and airports. Wi-Fi

2079-569: Is a trademark of the Wi-Fi Alliance , which restricts the use of the term " Wi-Fi Certified " to products that successfully complete interoperability certification testing. Non-compliant hardware is simply referred to as WLAN , and it may or may not work with " Wi-Fi Certified " devices. As of 2017, the Wi-Fi Alliance consisted of more than 800 companies from around the world. As of 2019, over 3.05 billion Wi-Fi-enabled devices are shipped globally each year. Wi-Fi uses multiple parts of

2178-554: Is about 20 m (66 ft) indoors, while some access points claim up to a 150 m (490 ft) range outdoors. Hotspot coverage can be as small as a single room with walls that block radio waves or as large as many square kilometers using many overlapping access points with roaming permitted between them. Over time, the speed and spectral efficiency of Wi-Fi have increased. As of 2019, some versions of Wi-Fi, running on suitable hardware at close range, can achieve speeds of 9.6 Gbit/s ( gigabit per second). A 1985 ruling by

2277-528: Is an Australian Government agency that is responsible for scientific research and its commercial and industrial applications. CSIRO works with leading organisations around the world. From its headquarters in Canberra, CSIRO maintains more than 50 sites across Australia and in France, Chile and the United States, employing about 5,500 people. Federally funded scientific research in Australia began in 1916 with

2376-432: Is divided into a multitude of channels . In the standards, channels are numbered at 5 MHz spacing within a band (except in the 60 GHz band, where they are 2.16 GHz apart), and the number refers to the centre frequency of the channel. Although channels are numbered at 5 MHz spacing, transmitters generally occupy at least 20 MHz, and standards allow for neighbouring channels to be bonded together to form

2475-433: Is located on North Stradbroke Island, a 27,700-hectare sand island, 30 minutes from Brisbane by boat. The island lies between the sub-tropical and temperate zones, and its waters feature a wide range of terrestrial, coastal and marine ecosystems. Mud flats surround the island, providing an estuarine environment which supports worms and bivalves and other tiny organisms. There is also a large dugong population which feeds off

2574-506: Is structured into Research Business Units, National Facilities and Collections, and Services. As at 2023, CSIRO's research areas are identified as "Impact science" and organised into the following Business Units: CSIRO manages national research facilities and scientific infrastructure on behalf of the nation to assist with the delivery of research. The national facilities and specialised laboratories are available to both international and Australian users from industry and research. As at 2019,

2673-641: Is submitted for certification. The lack of Wi-Fi certification does not necessarily imply that a device is incompatible with other Wi-Fi devices. The Wi-Fi Alliance may or may not sanction derivative terms, such as Super Wi-Fi , coined by the US Federal Communications Commission (FCC) to describe proposed networking in the UHF TV band in the US. Equipment frequently supports multiple versions of Wi-Fi. To communicate, devices must use

2772-417: Is used in applications such as motion detection and gesture recognition . Wi-Fi stations communicate by sending each other data packets , blocks of data individually sent and delivered over radio on various channels. As with all radio, this is done by the modulation and demodulation of carrier waves . Different versions of Wi-Fi use different techniques, 802.11b uses direct-sequence spread spectrum on

2871-671: The 1923 Imperial Conference 's call for colonies to broaden their economic base, in 1926 the Australian Parliament modified the principal Act for national scientific research (the Institute of Science and Industry Act 1920 ) by passing The Science and Industry Research Act 1926 . The same conference led to the creation of the Department of Scientific and Industrial Research in New Zealand. The new Act replaced

2970-693: The Australian Dung Beetle Project . Bornemissza, upon settling in Australia from Hungary in 1951, noticed that the pastureland was covered in dry cattle dung pads which did not seem to be recycled into the soil and caused areas of rank pasture which were unpalatable to the cattle. He proposed that the reason for this was that native Australian dung beetles, which had co-evolved alongside the marsupials (which produce dung very different in its composition from cattle), were not adapted to utilise cattle dung for their nutrition and breeding since cattle had only relatively recently been introduced to

3069-636: The Australian House of Representatives that in relation to the worker's compensation claim for psychological injuries of ex-CSIRO employee, Martin Williams, which was vigorously defended by Comcare on the advice of the CSIRO, that CSIRO officers had provided false testimony on no less than 128 occasions under oath when the matter went before the Administrative Appeals Tribunal . Mirabella stated, "even in establishing

3168-551: The Eduroam international authentication infrastructure. In the early 2000s, many cities around the world announced plans to construct citywide Wi-Fi networks. There are many successful examples; in 2004, Mysore (Mysuru) became India's first Wi-Fi-enabled city. A company called WiFiyNet has set up hotspots in Mysore, covering the whole city and a few nearby villages. In 2005, St. Cloud, Florida and Sunnyvale, California , became

3267-654: The Great Depression , research was extended into manufacturing and other secondary industries. In 1949 the Act was changed again, and the entity name amended to the Commonwealth Scientific and Industrial Research Organisation. The amendment enlarged and reconstituted the organisation and its administrative structure. Under Ian Clunies Ross as chairman, CSIRO pursued new areas such as radio astronomy and industrial chemistry. CSIRO still operates under

3366-505: The IEEE 802 protocol family and is designed to work seamlessly with its wired sibling, Ethernet . Compatible devices can network through wireless access points with each other as well as with wired devices and the Internet. Different versions of Wi-Fi are specified by various IEEE 802.11 protocol standards, with different radio technologies determining radio bands, maximum ranges, and speeds that may be achieved. Wi-Fi most commonly uses

3465-853: The Wi-Fi Alliance introduced simplified Wi-Fi generational numbering to indicate equipment that supports Wi-Fi 4 ( 802.11n ), Wi-Fi 5 ( 802.11ac ) and Wi-Fi 6 ( 802.11ax ). These generations have a high degree of backward compatibility with previous versions. The alliance has stated that the generational level 4, 5, or 6 can be indicated in the user interface when connected, along with the signal strength. The most important standards affecting Wi‑Fi are: 802.11a, 802.11b, 802.11g, 802.11n ( Wi-Fi 4 ), 802.11h, 802.11i, 802.11-2007, 802.11–2012, 802.11ac ( Wi-Fi 5 ), 802.11ad, 802.11af, 802.11-2016, 802.11ah, 802.11ai, 802.11aj, 802.11aq , 802.11ax ( Wi-Fi 6 ), 802.11ay . Wi-Fi technology may be used to provide local network and Internet access to devices that are within Wi-Fi range of one or more routers that are connected to

3564-455: The 11 permitted in the United States for the 2.4 GHz band, while Japan has three more (12–14). 802.11a/h/j/n/ac/ax can use the 5 GHz U-NII band , which, for much of the world, offers at least 23 non-overlapping 20 MHz channels. This is in contrast to the 2.4 GHz frequency band where the channels are only 5 MHz wide. In general, lower frequencies have longer range but have less capacity. The 5 GHz bands are absorbed to

3663-608: The 2.4 gigahertz (120 mm) UHF and 5 gigahertz (60 mm) SHF radio bands, with the 6 gigahertz SHF band used in newer generations of the standard; these bands are subdivided into multiple channels. Channels can be shared between networks, but, within range, only one transmitter can transmit on a channel at a time. Wi-Fi's radio bands work best for line-of-sight use. Many common obstructions, such as walls, pillars, home appliances, etc., may greatly reduce range, but this also helps minimize interference between different networks in crowded environments. The range of an access point

3762-408: The 5 GHz band, 20 MHz, 40 MHz, 80 MHz, and 160 MHz channels are permitted with some restrictions, giving much faster connections. Wi-Fi is part of the IEEE 802 protocol family. The data is organized into 802.11 frames that are very similar to Ethernet frames at the data link layer, but with extra address fields. MAC addresses are used as network addresses for routing over

3861-427: The 802.11 protocol was released in 1997, and provided up to 2 Mbit/s link speeds. This was updated in 1999 with 802.11b to permit 11 Mbit/s link speeds. In 1999, the Wi-Fi Alliance formed as a trade association to hold the Wi-Fi trademark under which most IEEE 802.11 products are sold. The major commercial breakthrough came with Apple Inc. adopting Wi-Fi for their iBook series of laptops in 1999. It

3960-611: The Advisory Council of Science and Industry, was established in 1916 on the initiative of prime minister Billy Hughes . However, the advisory council struggled with insufficient funding during the First World War. In 1920 the council was renamed the Commonwealth Institute of Science and Industry, and was led by George Handley Knibbs (1921–26), but continued to struggle financially. Implementing

4059-550: The Ars Technica piece. Total income to CSIRO from the patent is currently estimated at nearly $ 430 million. On 14 June 2012, the CSIRO inventors received the European Patent Office (EPO) European Inventor Award (EIA), in the category of "Non-European Countries". On 14 July 2011, Greenpeace activists vandalised a crop of GM wheat, circumventing the scientific trials being undertaken. Greenpeace

In an ABC radio interview, Spash called for a Senate enquiry into the affair and the role played by senior management and the Science Minister. After these events, the Sydney Morning Herald reported that "Questions are being raised about the closeness of BHP Billiton and the CSIRO under its chief executive, Megan Clark". After his resignation, an unedited version of

4257-449: The CSIRO gained worldwide attention, including some criticism, for promoting a high- protein , low- carbohydrate diet of their own creation called Total Wellbeing Diet . The CSIRO published the diet in a book which sold over half a million copies in Australia and over 100,000 overseas. The diet was criticised in an editorial by Nature for giving scientific credence to a "fashionable" diet sponsored by meat and dairy industries. In

4356-417: The CSIRO on 1 January 2015, caused an international outcry after describing Australia's national climate change discussion as "more like religion than science," a week after announcing hundreds of job cuts to the organisation that will reduce the effectiveness of its climate research team. In "an open letter to the Australian Government and CSIRO", 2,800 of the leading climate scientists from 60 countries say

4455-573: The CSIRO's WLAN prototype test bed was chosen as Australia's contribution to the exhibition A History of the World in 100 Objects held in the National Museum of Australia . The name Wi-Fi , commercially used at least as early as August 1999, was coined by the brand-consulting firm Interbrand. The Wi-Fi Alliance had hired Interbrand to create a name that was "a little catchier than 'IEEE 802.11b Direct Sequence'." According to Phil Belanger,

4554-615: The Internet. The coverage of one or more interconnected access points can extend from an area as small as a few rooms to as large as many square kilometres. Coverage in the larger area may require a group of access points with overlapping coverage. For example, public outdoor Wi-Fi technology has been used successfully in wireless mesh networks in London. An international example is Fon . Wi-Fi provides services in private homes, businesses, as well as in public spaces. Wi-Fi hotspots may be set up either free of charge or commercially, often using

4653-594: The LAN. Wi-Fi's MAC and physical layer (PHY) specifications are defined by IEEE 802.11 for modulating and receiving one or more carrier waves to transmit the data in the infrared, and 2.4, 3.6 , 5, 6, or 60 GHz frequency bands. They are created and maintained by the IEEE LAN/MAN Standards Committee ( IEEE 802 ). The base version of the standard was released in 1997 and has had many subsequent amendments. The standard and amendments provide

4752-619: The Queensland government to permit the university to take over part of the station, and develop its teaching and research facilities. The laboratory was renamed the Dunwich Marine Station (DMS) in 1961, becoming the first marine station managed by the University of Queensland. It would be joined by the Heron Island Research Station in the 1970s. Facilities were basic, with a bunkhouse, two-storey lab, engine room and kitchen/mess hall. Livestock roamed

4851-661: The Radiata technology in order to focus on software development and emerging new technologies. Controversy over the CSIRO patent arose in 2006 after the organisation won an injunction against Buffalo Technology in an infringement suit filed in Federal Court in the Eastern District of Texas. The injunction was subsequently suspended on appeal, with the Court of Appeals for the Federal Circuit finding that

4950-570: The U.S. Federal Communications Commission released parts of the ISM bands for unlicensed use for communications. These frequency bands include the same 2.4 GHz bands used by equipment such as microwave ovens , and are thus subject to interference. In 1991 in Nieuwegein , the NCR Corporation and AT&T invented the precursor to 802.11, intended for use in cashier systems, under

5049-543: The Wi-Fi Alliance did use the advertising slogan "The Standard for Wireless Fidelity" for a short time after the brand name was created, and the Wi-Fi Alliance was also called the "Wireless Fidelity Alliance Inc." in some publications. IEEE is a separate, but related, organization and their website has stated "WiFi is a short name for Wireless Fidelity". The name Wi-Fi was partly chosen because it sounds similar to Hi-Fi , which consumers take to mean high fidelity or high quality . Interbrand hoped consumers would find

The shadow minister for innovation, industry, science and research, Sophie Mirabella , wrote to the government requesting it establish an inquiry. Mirabella said she is aware of as many as 100 cases of alleged workplace harassment. On 20 July 2012 Comcare issued CSIRO with an Improvement Notice with regard to handling and management of workplace misconduct/code of conduct type investigations and allegations. On 24 June 2013 Mirabella advised

5247-604: The announcement of cuts to the CSIRO's Oceans and Atmosphere research program has alarmed the global climate research community. They say the decision shows a lack of insight and a misunderstanding of the importance of the depth and significance of Australian contributions to global and regional climate research. The CSIRO has been the target of successive funding cuts under the Morrison government , starting with cuts targeting climate science research initiated by Tony Abbott . Wi-Fi Wi-Fi ( / ˈ w aɪ f aɪ / )

5346-605: The basis for wireless network products using the Wi-Fi brand. While each amendment is officially revoked when incorporated in the latest version of the standard, the corporate world tends to market to the revisions because they concisely denote capabilities of their products. As a result, in the market place, each revision tends to become its own standard. In addition to 802.11, the IEEE 802 protocol family has specific provisions for Wi-Fi. These are required because Ethernet's cable-based media are not usually shared, whereas with wireless all transmissions are received by all stations within

5445-481: The capability. Some laptops that have a cellular modem card can also act as mobile Internet Wi-Fi access points. Many traditional university campuses in the developed world provide at least partial Wi-Fi coverage. Carnegie Mellon University built the first campus-wide wireless Internet network, called Wireless Andrew , at its Pittsburgh campus in 1993 before Wi-Fi branding existed. Many universities collaborate in providing Wi-Fi access to students and staff through

5544-569: The channel to be idle at the same time and thus begin transmission simultaneously. A collision happens when a station receives signals from multiple stations on a channel at the same time. This corrupts the transmitted data and can require stations to re-transmit. The lost data and re-transmission reduces throughput, in some cases severely. The 802.11 standard provides several distinct radio frequency ranges for use in Wi-Fi communications: 900  MHz , 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, 6 GHz and 60 GHz bands . Each range

5643-428: The continent in the 1880s. The Australian Dung Beetle Project sought, therefore, to introduce species of dung beetle from South Africa and Europe (which had co-evolved alongside bovids) in order to improve the fertility and quality of cattle pastures. Twenty-three species were successfully introduced throughout the duration of the project and also had the effect of reducing the pestilent bush fly population by 90%. CSIRO

5742-477: The creation of the Advisory Council of Science and Industry. However, the council struggled due to insufficient funding. In 1926, research efforts were revitalised with the establishment of the Council for Scientific and Industrial Research (CSIR), which strengthened national science leadership and increased research funding. CSIR grew rapidly, achieving significant early successes. In 1949, legislative changes led to

5841-519: The database. Signal fluctuations can cause errors, which can be reduced with noise-filtering techniques. For low precision, integrating Wi-Fi data with geographical and time information has been proposed. The Wi-Fi RTT capability introduced in IEEE 802.11mc allows for positioning based on round trip time measurement, an improvement over the RSSI method. The IEEE 802.11az standard promises further improvements in geolocation accuracy. Wi-Fi sensing

In response to the allegations Clark commissioned Dennis Pearce, who is assisted by an investigation team from HWL Ebsworth Lawyers, to conduct an independent investigation into allegations of workplace bullying and other unreasonable behaviour. Mirabella continued to question the independence of

6534-717: The institute with the Council for Scientific and Industrial Research (CSIR). With encouragement from prime minister Stanley Bruce , strengthened national science leadership and increased research funding, CSIR grew rapidly and achieved significant early successes. The council was structured to represent the federal structure of government in Australia, and had state-level committees and a central council. In addition to an improved structure, CSIR benefited from strong bureaucratic management under George Julius , David Rivett , and Arnold Richardson. Research focused on primary and secondary industries. Early in its existence, CSIR established divisions studying animal health and animal nutrition. After

NCR's Vic Hayes , who held the chair of IEEE 802.11 for ten years, along with Bell Labs engineer Bruce Tuch, approached the Institute of Electrical and Electronics Engineers (IEEE) to create a standard and were involved in designing the initial 802.11b and 802.11a specifications within the IEEE. They have both been subsequently inducted into the Wi-Fi NOW Hall of Fame. In 1989 in Australia,

6930-452: The name catchy, and that they would assume this wireless protocol has high fidelity because of its name. Other technologies intended for fixed points, including Motorola Canopy , are usually called fixed wireless . Alternative wireless technologies include Zigbee , Z-Wave , Bluetooth and mobile phone standards . To connect to a Wi-Fi LAN, a computer must be equipped with a wireless network interface controller . The combination of

7029-674: The organisation being accused of being "Australia's biggest patent troll", a wrathful "patent bully", and of imposing a "WiFi tax" on American innovation. Further fuel was added to the controversy after a settlement with the carriers, worth around $ 229 million, was announced in March 2012. Encouraged in part by an announcement by the Australian Minister for Tertiary Education, Skills Science and Research, Senator Chris Evans, an article in Ars Technica portrayed CSIRO as

7128-471: The paper was released by Spash as a discussion paper, and later published as an academic journal article. On 11 April 2013, the Sydney Morning Herald ran a story on how CSIRO had "duped" the Swiss-based pharmaceutical giant Novartis into purchasing an anti-counterfeit technology for its vials of injectable Voltaren . The invention was marketed by a small Australian company called DataTrace DNA as

7227-402: The previous five years, polling to create a long-term view of how Australians viewed global warming and their support for action. In the previous 2013 poll, 86 per cent agreed with the statement that climate change was occurring and only 7.6 per cent disagreed. On 11 February 2016, Dr Larry Marshall – a former venture capitalist with Southern Cross Venture Holdings, who had been appointed CEO of

7326-747: The priorities and structure of CSIRO, and the teams and facilities that implement its research, have changed as Australia's scientific challenges have evolved. Numerous CSIRO scientists have gone onto distinguished careers in the university sector. Several have been appointed to the role of Vice-Chancellor/President. They include: Sir George Currie (UNZ 1952–62, Western Australia 1945–52), Paul Wellings CBE (Wollongong 2012–21, Lancaster 2002–12), Michael Barber AO (Flinders 2008–14), Mark Smith CBE (Southampton 2019–ff, Lancaster 2012–19), Annabelle Duncan (UNE 2014–19), Attila Brungs (UNSW 2021–ff, UTS 2014–21), Alex Zelinsky AO (Newcastle (2018–ff), Andrew Parfitt (UTS 2021–ff), Chris Moran (UNE 2023–ff). In 2005

7425-566: The project, which was to be completed in 2015. Wi-Fi positioning systems use known positions of Wi-Fi hotspots to identify a device's location. It is used when GPS isn't suitable due to issues like signal interference or slow satellite acquisition. This includes assisted GPS , urban hotspot databases, and indoor positioning systems. Wi-Fi positioning relies on measuring signal strength ( RSSI ) and fingerprinting. Parameters like SSID and MAC address are crucial for identifying access points. The accuracy depends on nearby access points in

7524-618: The provisions of the 1949 Act in a wide range of scientific inquiry. Participation by women in CSIRO research was severely limited by the Australian government policy, in place until 1966, forcing women public servants out of their jobs when they married. Even unmarried women were considered a poor investment because they might eventually marry. Single women such as Helen Newton Turner nevertheless made major contributions. Since 1949, CSIRO has expanded its activities to almost every field of primary, secondary and tertiary industry, including

7623-551: The range that employ that radio channel. While Ethernet has essentially negligible error rates, wireless communication media are subject to significant interference. Therefore, the accurate transmission is not guaranteed so delivery is, therefore, a best-effort delivery mechanism. Because of this, for Wi-Fi, the Logical Link Control (LLC) specified by IEEE 802.2 employs Wi-Fi's media access control (MAC) protocols to manage retries without relying on higher levels of

7722-504: The receiver uses the destination address to determine whether the transmission is relevant to the station or should be ignored. A scheme known as carrier-sense multiple access with collision avoidance (CSMA/CA) governs the way stations share channels. With CSMA/CA stations attempt to avoid collisions by beginning transmission only after the channel is sensed to be idle, but then transmit their packet data in its entirety. CSMA/CA cannot completely prevent collisions, as two stations may sense

7821-457: The renaming of the organisation as Commonwealth Scientific and Industrial Research Organisation (CSIRO). Notable developments by CSIRO have included the invention of atomic absorption spectroscopy , essential components of the early Wi-Fi technology, development of the first commercially successful polymer banknote , the invention of the insect repellent in Aerogard and the introduction of

7920-399: The rest of the industry becoming the first to reach a settlement of its dispute with CSIRO. This agreement was followed quickly by settlements with Microsoft, Fujitsu and Asus and then Dell, Intel, Nintendo , Toshiba , Netgear, Buffalo, D-Link , Belkin , SMC , Accton , and 3Com . The controversy grew after CSIRO sued US carriers AT&T , Verizon and T-Mobile in 2010, with

8019-489: The roles and responsibilities of the chair and chief executive have changed many times. From 1927 to 1986 the head of CSIR (and from 1949, CSIRO) was the chairman, who was responsible for the management of the organisation, supported by the chief executive. From 1 July 1959 to 4 December 1986 CSIRO had no chief executive; the chairman undertook both functions. In 1986, when the Australian Government changed

8118-400: The same channel also means that the data bandwidth is shared, so for example, available throughput to each device is halved when two stations are actively transmitting. As with other IEEE 802 LANs, stations come programmed with a globally unique 48-bit MAC address. The MAC addresses are used to specify both the destination and the source of each data packet. On the reception of a transmission,

8217-515: The same wireless channel, SSID, and other settings that have wirelessly connected, usually to the same access point. Each BSS is identified by a MAC address called the BSSID . The IEEE does not test equipment for compliance with their standards. The Wi-Fi Alliance was formed in 1999 to establish and enforce standards for interoperability and backward compatibility , and to promote wireless local-area-network technology. The Wi-Fi Alliance enforces

8316-536: The seagrass. Coral reefs remain close by at Peel Island . Research at the station evolved from the study of oyster and sea mullet fisheries in Moreton Bay, to more general marine research. CSIRO abandoned the station in 1959, and it was taken over by the University of Queensland. Prof. William Stephenson , a biologist at the university, had used the station regularly as a teaching destination for undergraduate and postgraduate student field trips. He petitioned

8415-447: The standard on reasonable and non-discriminatory terms. In 1999, Cisco Systems , Inc. and Broadcom Corporation each invested A$ 4 million in Radiata, representing an 11% stake for each investor and valuing the company at around A$ 36 million. In September 2000, Radiata demonstrated a chip set complying with the recently finalised IEEE 802.11a Wi-Fi standard, and capable of handling transmission rates of up to 54 Mbit/s, at

8514-427: The streets and foreshore, and students had easy access to Rainbow Channel. In the 1990s, the facilities were showing wear and tear and needed to be upgraded for teaching purposes. Funding was sought from the university in 1997 to demolish the old buildings, and construct a modern, purpose-designed teaching and research facility. This would accommodate 96 students and researchers and provide high-speed internet access and

8613-521: The structure of CSIRO to include a board of non-executive members plus the chief executive to lead CSIRO, the roles changed. The chief executive is now responsible for management of the organisation in accordance with the strategy, plans and policies approved by the CSIRO Board which, led by the chair of the board, is responsible to the Australian Government for the overall strategy, governance and performance of CSIRO. As with its governance structure,

8712-445: The structure. Similarly, battery-powered routers may include a mobile broadband modem and a Wi-Fi access point. When subscribed to a cellular data carrier, they allow nearby Wi-Fi stations to access the Internet. Many smartphones have a built-in mobile hotspot capability of this sort, though carriers often disable the feature, or charge a separate fee to enable it. Standalone devices such as MiFi - and WiBro -branded devices provide

8811-429: The subject of U.S. patent 5,487,069 , which was granted on 23 January 1996. In 1997 Macquarie University professor David Skellern and his colleague Neil Weste established the company Radiata, Inc., which took a nonexclusive licence to the CSIRO patent for the purpose of developing commercially viable integrated circuit devices implementing the patented technology. During this period, the IEEE 802.11 Working Group

8910-762: The use of the Wi-Fi brand to technologies based on the IEEE 802.11 standards from the IEEE. Manufacturers with membership in the Wi-Fi Alliance, whose products pass the certification process, gain the right to mark those products with the Wi-Fi logo. Specifically, the certification process requires conformance to the IEEE 802.11 radio standards, the WPA and WPA2 security standards, and the EAP authentication standard. Certification may optionally include tests of IEEE 802.11 draft standards, interaction with cellular-phone technology in converged devices, and features relating to security set-up, multimedia, and power-saving. Not every Wi-Fi device

9009-685: The world's first solar radiospectrograph, and from 1967 the 3-kilometre-diameter (1.9 mi) radioheliograph at Culgoora in New South Wales. For three decades, the Division of Radiophysics had a world-leading role in solar research, attracting prominent solar physicists from around the world. CSIRO owned the first computer in Australia, CSIRAC , built as part of a project began in the Sydney Radiophysics Laboratory in 1947. The CSIR Mk 1 ran its first program in 1949,

9108-639: The world. The UK has planned a similar project across major cities of the country, with the project's first implementation in the London Borough of Camden . Officials in South Korea's capital Seoul were moving to provide free Internet access at more than 10,000 locations around the city, including outdoor public spaces, major streets, and densely populated residential areas. Seoul was planning to grant leases to KT, LG Telecom, and SK Telecom. The companies were supposed to invest $ 44 million in

9207-516: Was being suppressed. At the time, the Labor government was trying to get such a scheme through the Senate. After the debate, the Science Minister, Kim Carr, was forced to release the paper, but when doing so in the Senate he also delivered a letter from the CEO of the CSIRO, Megan Clark , which attacked the report's author and threatened him with unspecified punishment. The author of the paper, Clive Spash,

9306-453: Was cited in the press as having been bullied and harassed, and later gave a radio interview about this. In the midst of the affair, CSIRO management had considered releasing the paper with edits that Nature reported would be "tiny". Spash claimed the changes actually demanded amounted to censorship and resigned. He later posted on his website a document detailing the text that CSIRO management demanded be deleted; by itself, this document forms

9405-575: Was developing the 802.11a wireless LAN standard. CSIRO did not participate directly in the standards process, however David Skellern was an active participant as secretary of the Working Group, and representative of Radiata. In 1998 it became apparent that the CSIRO patent would be pertinent to the standard. In response to a request from Victor Hayes of Lucent Technologies, who was chair of the 802.11 Working Group, CSIRO confirmed its commitment to make non-exclusive licenses available to implementers of

9504-448: Was done with the knowledge of key CSIRO personnel. CSIRO has since conducted a full review of the allegations and found no evidence to support them. Around 2008–2012, CSIRO fell under the spotlight for allegedly exhibiting a culture of workplace bullying and harassment. Former CSIRO employees started to surface with experiences of workplace bullying and other unreasonable behaviour by current and former CSIRO staff members. CSIRO took

9603-471: Was forced to pay reparations to CSIRO of $ 280,000 for the criminal damage, and were accused by the sentencing judge, Justice Hilary Penfold , of cynically using junior members of the organisation with good standing to avoid custodial sentences, while the offenders were given 9-month suspended sentences. Following the attack Greenpeace criticised CSIRO for a close relationship with industry that had led to an increase in genetically modified crops , even though

9702-424: Was the first Australian organisation to start using the Internet and was able to register the second-level domain csiro.au (as opposed to csiro.org.au or csiro.com.au). Guidelines were introduced in 1996 to regulate the use of the .au domain. When CSIR was formed in 1926, it was led initially by an executive committee of three people, two of whom were designated as the chairman and the chief executive. Since then

9801-429: Was the first mass consumer product to offer Wi-Fi network connectivity, which was then branded by Apple as AirPort . This was in collaboration with the same group that helped create the standard: Vic Hayes , Bruce Tuch, Cees Links , Rich McGinn, and others from Lucent . In the year 2000, Radiata, a group of Australian scientists connected to the CSIRO, were the first to use the 802.11a standard on chips connected to
