Timex Datalink or Timex Data Link is a line of early smartwatches manufactured by Timex and is considered a wristwatch computer. It is the first watch capable of downloading information wirelessly from a computer. As the name implies, datalink watches are capable of data transfer through linking with a computer. The Datalink line was introduced in 1994 and it was co-developed with Microsoft as a wearable alternative to mainstream PDAs with additional attributes such as water resistance, that PDAs lacked, and easy programmability. The watch was demonstrated by Bill Gates on 21 June 1994 in a presentation where he downloaded information from a computer monitor using bars of light and then showed to the audience the downloaded appointments and other data. The early models included models 50, 70, 150 and model 150s (small size). The model numbers indicated the approximate number of phone numbers that could be stored in the watch memory. These early models were, at the time of their introduction, the only watches to bear the Microsoft logo. The watches have been certified by NASA for space travel and have been used by astronauts and cosmonauts in space missions . There had been an evolution over the years as to the number and type of entries that can be stored in the various watch models as well as the mode of data transfer between computer and watch. At the time of its introduction the watch was considered high-tech .
100-681: There is also the Timex Beepwear Datalink series, featuring wearable pagers using the Timex datalink platform which also function as electronic organisers. Although there are other watches capable of storing all kinds of data, most had either a small keyboard or buttons, which could be used to input data. In most cases data was lost when the battery expired. Upon introduction of the Timex Datalink models, "data watches" such as those from Casio were noted as selling for "between
200-565: A computer keyboard . The actions in a GUI are usually performed through direct manipulation of the graphical elements. Beyond computers, GUIs are used in many handheld mobile devices such as MP3 players, portable media players, gaming devices, smartphones and smaller household, office and industrial controls . The term GUI tends not to be applied to other lower- display resolution types of interfaces , such as video games (where head-up displays ( HUDs ) are preferred), or not including flat screens like volumetric displays because

400-474: A GUI and some level of a CLI, although the GUIs usually receive more attention. GUI wrappers find a way around the command-line interface versions (CLI) of (typically) Linux and Unix-like software applications and their text-based UIs or typed command labels. While command-line or text-based applications allow users to run a program non-interactively, GUI wrappers atop them avoid the steep learning curve of
500-532: A button until the changeover was effected. All Datalink models had the Indiglo night light. The earlier models included many PDA-type functions such as anniversaries, appointments and phone directory, but did not have functions such as stopwatch and countdown timer. They had five alarms. To add functionality, in 1997 Timex introduced the Ironman Triathlon Datalink series with features of
600-410: A combination of technologies and devices to provide a platform that users can interact with, for the tasks of gathering and producing information. A series of elements conforming a visual language have evolved to represent information stored in computers. This makes it easier for people with few computer skills to work with and use computer software. The most common combination of such elements in GUIs
700-705: A dedicated communications link. Automated monitoring and escalation software clients, often used in hospitals, IT departments and alarm companies, tend to prefer direct connections because of the increased reliability. Small paging systems, such as those used in restaurant and retail establishments, often integrate a keyboard and paging system into a single box, reducing both cost and complexity. Paging systems support several popular direct connection protocols, including TAP , TNPP, SNPP and WCTP , as well as proprietary modem- and socket-based protocols. Additionally, organizations often integrate paging systems with their Voice-mail and PBX systems, conceptually attaching pagers to
800-508: A grid of items with rows of text extending sideways from the icon. Multi-row and multi-column layouts commonly found on the web are "shelf" and "waterfall". The former is found on image search engines , where images appear with a fixed height but variable length, and is typically implemented with the CSS property and parameter display: inline-block; . A waterfall layout found on Imgur and TweetDeck with fixed width but variable height per item
900-402: A household name", although this robustness was reported as making the product more like "the kind of "chunky, clunky watches that divers prefer", being around one-and-a-half inches in diameter and standing "over half an inch proud of the wrist". The Timex Datalink watches downloaded data wirelessly by illuminating a computer screen with a changing display encoding information to transfer, which
1000-430: A local base station, or through a telephone number assigned to each individual pager. In the 1990s, pagers became popular among the general public as a cheaper, smaller, and more reliable alternative to mobile phones . Bell System Bellboy radio pagers each used three reed receiver relays, each relay tuned to one of 33 different frequencies, selectively ringing a particular customer when all three relays were activated at
1100-443: A message has been successfully delivered to a pager. Because of this, if a one-way pager is turned off or is not receiving a usable signal at the time a message is transmitted, the message will not be received and the sender of the message will not be notified of this fact. In the mid-1990s, some paging companies began offering a service, which allowed a customer to call their pager-number and have numeric messages read back to them. This

#17328014813781200-605: A mild disappointment for the wireless datalink purists, it gained widespread acceptance, because, although now tethered to the computer through the USB port during data transfer, the new watch featured greatly improved data transfer rates, greatly increased memory capacity and many additional and customizable modes of operation, as well as two way communication between the watch and computer. Its modes are user customizable, with hundreds of phone numbers, alarms and timer settings. It also features three time zones, each of which can be chosen as
1300-411: A minute. However, the mechanism required the use of a cathode-ray tube monitor, as opposed to a liquid-crystal or other kind of display. Transfer of data from the watch to the computer was also not permitted by this mechanism, but entries could be deleted on the watch or, in the case of to-do items, marked as done. When the watch's battery expired the data would be transferred again after replacement of
1400-499: A notebook adapter that incorporated a red LED and connected with the laptop through the serial port . During download, the LED flashed and the flashing programmed the watch much like the horizontal bars of the CRT. For systems without a serial port, a USB to serial adapter can be used to connect the Timex adapter to a USB port . Alternatively, DIY Notebook Adapter emulators can be used with
1500-416: A one-way pager is a passive receiver only (it sends no information back to the base station), its location cannot be tracked. However, this can also be disadvantageous, as a message sent to a pager must be broadcast from every paging transmitter in the pager's service area. Thus, if a pager has nationwide service, a message sent to it could be intercepted by criminals or law enforcement agencies anywhere within
1600-490: A paging network and are less subject to these delays. For this reason, older forms of message submission retain their usefulness for disseminating highly-important alerts to users such as emergency services personnel. Common paging protocols include TAP , FLEX , ReFLEX , POCSAG , GOLAY, ERMES and NTT. Past paging protocols include Two-tone and 5/6-tone. In the United States, pagers typically receive signals using
1700-435: A paging system which includes one or more fixed transmitters (or in the case of response pagers and two-way pagers, one or more base stations ), as well as a number of pagers carried by mobile users. These systems can range from a restaurant system with a single low power transmitter, to a nationwide system with thousands of high-power base stations. Pagers were developed in the 1950s and 1960s, and became widely used by
1800-466: A portable receiver that would usually vibrate, flash, or beep when a table becomes free or when their meal is ready. Pagers have been popular with birdwatchers in Great Britain and Ireland since 1991, with companies Rare Bird Alert and Birdnet Information offering news of rare birds sent to pagers that they sell. Today, companies like Visiplex offer similar solutions for onsite pager systems in
1900-506: A program was busy. Additionally, it was the first GUI to introduce something resembling Virtual Desktops . Windows 95 , accompanied by an extensive marketing campaign, was a major success in the marketplace at launch and shortly became the most popular desktop operating system. In 2007, with the iPhone and later in 2010 with the introduction of the iPad , Apple popularized the post-WIMP style of interaction for multi-touch screens, and those devices were considered to be milestones in
2000-474: A retail store, airline self-ticket and check-in, information kiosks in a public space, like a train station or a museum, and monitors or control screens in an embedded industrial application which employ a real-time operating system (RTOS). Cell phones and handheld game systems also employ application specific touchscreen GUIs. Newer automobiles use GUIs in their navigation systems and multimedia centers, or navigation multimedia center combinations. A GUI uses
2100-414: A short sequence of words and symbols. Custom functions may be used to facilitate access to frequent actions. Command-line interfaces are more lightweight , as they only recall information necessary for a task; for example, no preview thumbnails or graphical rendering of web pages. This allows greater efficiency and productivity once many commands are learned. But reaching this level takes some time because

#17328014813782200-475: A simple chronograph could be added as an external application also known as a wristapp. The wristapps also included a notepad capable of storing forty words. The time and date parts of the digital display of the Datalink watches consisted of two main rows of seven segment displays , while the lower portion was a dot matrix display with scrolling capabilities. In time display mode, the dot matrix portion of
2300-496: A single transmitter tower. The system was manufactured by the Reevesound Company and operated by Telanswerphone. In 1960, John Francis Mitchell combined elements of Motorola 's walkie-talkie and automobile radio technologies to create the first transistorized pager, and from that time, paging technology continued to advance and pager adoption among emergency personnel was still popular as of July 2016. In 1962,

WIMPs extensively use modes , as the meaning of all keys and clicks on specific positions on the screen are redefined all the time. Command-line interfaces use modes only in limited forms, such as for current directory and environment variables . Most modern operating systems provide both
2500-422: A telephone extension and set up web portals to integrate pagers into other parts of their enterprise. A paging system alerts a pager (or group of pagers) by transmitting information over an RF channel, including an address and message information. This information is formatted using a paging protocol, such as 2-tone, 5/6-tone, GOLAY, POCSAG , FLEX , ERMES , or NTT. Two-way pagers and response pagers typically use

The Datalink models also offered water resistance to a depth of 100 metres, Timex's Indiglo backlighting, and "the build quality that helped make Timex
2700-443: Is a form of user interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation . In many applications, GUIs are used instead of text-based UIs , which are based on typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs), which require commands to be typed on

In 2006, Hillcrest Labs introduced the first ZUI for television. Other innovations include the menus on the PlayStation 2 , the menus on the Xbox , Sun's Project Looking Glass , Metisse , which was similar to Project Looking Glass, BumpTop , where users can manipulate documents and windows with realistic movement and physics as if they were physical documents, Croquet OS , which
3000-402: Is compatible with Windows versions Windows 3.1 to Windows XP . The watch was compatible with Microsoft's Schedule+ time management software. For the Datalink 70 model, the time needed to download seventy phone numbers was about twenty seconds. On the resin strap of the Timex Datalink 50 model 70301, there is a print with binary numbers which are actually ASCII . The numbers on one half of

In both cases, the operating system transforms windows on-the-fly while continuing to update the content of those windows. The GUI is usually WIMP-based, although occasionally other metaphors surface, such as those used in Microsoft Bob , 3dwm, File System Navigator, File System Visualizer , 3D Mailbox, and GopherVR . Zooming (ZUI)
3300-440: Is the windows, icons, text fields, canvases, menus, pointer ( WIMP ) paradigm, especially in personal computers . The WIMP style of interaction uses a virtual input device to represent the position of a pointing device's interface , most often a mouse , and presents information organized in windows and represented with icons . Available commands are compiled together in menus, and actions are performed making gestures with
3400-440: Is the case with many new technologies, the functionality of the pager shifted from necessary professional use to a social tool integrated in one's personal life. During the rise of the pager, it became the subject of various forms of media, most notably in the 1990s hip-hop scene. Popular artists from the era, including Ice Cube , Method Man , and A Tribe Called Quest , began referencing newly developed mobile technologies such as
3500-555: Is usually implemented by specifying column-width: . Smaller app mobile devices such as personal digital assistants (PDAs) and smartphones typically use the WIMP elements with different unifying metaphors, due to constraints in space and available input devices. Applications for which WIMP is not well suited may use newer interaction techniques , collectively termed post-WIMP UIs.

They are also featured at the online exhibit of
3700-654: The Bell System , the U.S. telephone monopoly, presented its Bellboy radio paging system at the Seattle World's Fair. Bellboy was the first commercial system for personal paging. It also marked one of the first consumer applications of the transistor (invented by Bell Labs in 1947), for which three Bell Labs inventors received a Nobel Prize in Physics in 1956. Solid-state circuitry enabled the Bellboy pager, about
3800-529: The FLEX protocol in the 900 MHz band. Commercial paging transmitters typically radiate 1000 watts of effective power , resulting in a much wider coverage area per tower than a mobile phone transmitter, which typically radiates around 0.6 watts per channel. Although 900 MHz FLEX paging networks tend to have stronger in-building coverage than mobile phone networks, commercial paging service providers will work with large institutions to install repeater equipment in

The Beepwear marketing motto was: "One beeping great watch". It
4100-1185: The ReFLEX protocol. Modern paging systems typically use multiple base transmitters to modulate the same signal on the same RF channel, a design approach called simulcast . This type of design enables pagers to select the strongest signal from several candidate transmitters using FM capture , thereby improving overall system performance. Simulcast systems often use satellite to distribute identical information to multiple transmitters and GPS at each transmitter to precisely time its modulation relative to other transmitters. The coverage overlap, combined with use of satellite communications, can make paging systems more reliable than terrestrial based cellular networks in some cases, including during natural and human-made disaster. This resilience has led public safety agencies to adopt pagers over cellular and other commercial services for critical messaging. Pagers themselves vary from very cheap and simple beepers, to more complex personal communications equipment, falling into eight main categories. Pagers have certain privacy advantages and disadvantages compared with cellular phones. Since

4700-627: The 1970s, Engelbart's ideas were further refined and extended to graphics by researchers at Xerox PARC and specifically Alan Kay , who went beyond text-based hyperlinks and used a GUI as the main interface for the Smalltalk programming language , which ran on the Xerox Alto computer , released in 1973. Most modern general-purpose GUIs are derived from this system. The Xerox PARC GUI consisted of graphical elements such as windows , menus , radio buttons , and check boxes . The concept of icons
4800-734: The 1980s through the late 1990s and early 2000s. Later in the 21st century, the widespread availability of cellphones and smartphones with text messaging capability has greatly diminished the pager industry. Nevertheless, pagers continue to be used by some emergency services and public safety personnel , because modern pager systems' coverage overlap, combined with use of satellite communications , can make paging systems more reliable than terrestrial based cellular networks in some cases, including during natural and human-made disasters . This resilience has led public safety agencies to adopt pagers over cellular and other commercial services for critical messaging. The first telephone pager system

5400-537: The battery. The watch had a small lens at the top of its face used for data transmission by visible light. Data was transmitted from the CRT of the computer through a series of pulsating horizontal bars, that were focused by the lens and written to the watch EEPROM memory through an optoelectronic transducer operating in the visible light spectrum and employing optical scanning technology. The original Timex Datalink software with CRT synchronization support

Also, using the command line can become slow and error-prone when users must enter long commands comprising many parameters or several different filenames at once. However, windows, icons, menus, pointer ( WIMP ) interfaces present users with many widgets that represent and can trigger some of the system's available commands.

The U.S. paging industry generated $ 2.1 billion in revenue in 2008, down from $ 6.2 billion in 2003. In Canada, 161,500 Canadians paid $ 18.5 million for pager service in 2013. Telus , one of the three major mobile carriers, announced the end to its Canadian pager service as of 31 March 2015, but rivals Bell , Rogers and PageNet intend to continue service. In 2017
7200-425: The message, and the related capability to operate on very low signal levels, are not completely outclassed by their successors. Volunteer firefighters, EMS paramedics and rescue squad members usually carry pagers to alert them of emergency call outs for their department. These pagers receive a special tone from a fire department radio frequency. Restaurant pagers remain in wide use since the 2000s. Customers are given
7300-435: The methods of 3D graphics to project 3D GUI objects onto the screen. The use of 3D graphics has become increasingly common in mainstream operating systems (ex. Windows Aero , and Aqua (MacOS)) to create attractive interfaces, termed eye candy (which includes, for example, the use of drop shadows underneath windows and the cursor ), or for functional purposes only possible using three dimensions. For example, user switching
7400-470: The moon calculations and associated display graphics and others. The wristapps are written in assembly language . Invasion is an example of a game developed specifically for the watch. It is designed along the lines of Space Invaders , created by Jordi Perez. The game has been developed to showcase API instructions for primitive pixel displays such as the one used in the watch. The term primitive refers to displays of low resolution where one can discern
7500-577: The nationwide service area. On September 17, 2024, a massive attack against Hezbollah members in Lebanon and Syria was allegedly committed by Israel, who simultaneously detonated pagers that they were using. Lebanese Health authorities confirmed at least nine deaths and over 3,000 injuries as a result of the explosions. In February 2024, Hezbollah leader Hassan Nasrallah had told the group's members to use pagers instead of cell phones, claiming that Israel had infiltrated their mobile phone network. As
7600-838: The opportunity to leave the waiting area, but still be contacted. Paging systems are operated by commercial carriers, often as a subscription service and they are also operated directly by end users as private systems. Commercial carrier systems tend to cover a larger geographical area than private systems, while private systems tend to cover their limited area more thoroughly and deliver messages faster than commercial systems. In all systems, clients send messages to pagers, an activity commonly referred to as paging . System operators often assign unique phone numbers or email addresses to pagers (and pre-defined groups of pagers), enabling clients to page by telephone call, e-mail and SMS. Paging systems also support various types of direct connection protocols, which sacrifice global addressing and accessibility for
7700-606: The original and third-party software, like timex-datalink-arduino . The Datalink USB was introduced in 2003. It included the Timex Ironman Datalink USB (sport edition) and the Timex Datalink USB (dress edition) models. Apart from their external appearance, and the fact that the sport edition is water-resistant to 100 metres, while the dress edition is water resistant to 30 metres, the two models had identical specifications. Although initially
7800-519: The pager. A Tribe Called Quest's single "Skypager" directly speaks of the importance of such a wireless communication device, with group member Q-Tip stating that the Skypager "serves an important communicative function for a young professional with a full calendar". Three 6 Mafia 's "2-Way Freak," Sir Mix-A-Lot 's " Beepers " and " Bug a Boo " from Destiny's Child also make reference to pagers. Illicit drug dealers used pagers to great effect during
7900-403: The pointing device. A window manager facilitates the interactions between windows, applications , and the windowing system . The windowing system handles hardware devices such as pointing devices, graphics hardware, and positioning of the pointer. In personal computers , all these elements are modeled through a desktop metaphor to produce a simulation called a desktop environment in which
8000-631: The pressure placed on the service by the COVID-19 pandemic in England . In August 2020, a new procurement framework for clinical communications was launched which was intended to phase out pagers by the end of 2021, replacing them with "dedicated clinical-facing communication and tasks management tools" from 25 approved suppliers. In Japan, more than ten million pagers were active in 1996. On 1 October 2019, Japan's last paging service provider shut down radio signals and terminated its service. In Russia,
8100-626: The primary time display with the press of a button. The Datalink USB also introduced data protection through the use of a user generated password , a feature that the earlier models did not offer. The USB models also feature a rotating crown known as the Timex i-control . The Datalink USB supports software programs developed specifically for the watch similar to its predecessors. These programs are called wrist applications or wrist apps for short, and they are created by independent software developers . Timex has developed an application called WristApp SDK Installer . This application can facilitate
8200-534: The same time—a precursor of DTMF . The ReFLEX protocol was developed in the mid-1990s. As prices for mobile phones declined, small form factor phones like the Motorola StarTAC and the Nokia Series 40 line came on the market, cellular connectivity expanded, and digital phones adopted text messaging , most pager customers outside of specialist fields migrated to mobile phones toward the end of
8300-524: The size of a small TV remote device, to fit into a customer's pocket or purse, quite a feat at that time. The Bellboy was a terminal that notified the user when someone was trying to call them. When the person received an audible signal (a buzz) on the pager, the user found a telephone and called the service center, which informed the user of the caller's message. In the mid-1980s, tone and voice radio paging became popular among emergency responders and professionals. Tone and voice pagers were activated either by
8400-411: The strap encode, including capitalization, the text 'Listen To The Light'. The numbers on other half of the strap encode the text 'If You [ASCII-24] See', which, given that ASCII-24 is the 'Cancel' character or just 'CAN', makes the complete message 'Listen To The Light If You Can See'. The earlier models were the Datalink 50, Datalink 70, Datalink 150 and Datalink 150s, where the "s" was for small and it
8500-517: The system never reached commercial production. The first commercially available computer with a GUI was the 1979 PERQ workstation , manufactured by Three Rivers Computer Corporation. Its design was heavily influenced by the work at Xerox PARC. In 1981, Xerox eventually commercialized the ideas from the Alto in the form of a new and enhanced system – the Xerox 8010 Information System – more commonly known as
8600-505: The term is restricted to the scope of 2D display screens able to describe generic information, in the tradition of the computer science research at the Xerox Palo Alto Research Center . Designing the visual composition and temporal behavior of a GUI is an important part of software application programming in the area of human–computer interaction . Its goal is to enhance the efficiency and ease of use for
8700-446: The time could be set through normal use of the watch, the software also permitted the time to be updated using the transfer mechanism. Selecting the "Send to Watch" option in the Datalink software and pointing the watch face towards the screen at a distance of between six and twelve inches, guided by beeping sounds from the watch, resulted in the transfer of data at a rate that permitted around 1 KB or 70 entries to be sent in less than
8800-456: The underlying logical design of a stored program , a design discipline named usability . Methods of user-centered design are used to ensure that the visual language introduced in the design is well-tailored to the tasks. The visible graphical interface features of an application are sometimes referred to as chrome or GUI . Typically, users interact with information by manipulating visual widgets that allow for interactions appropriate to
8900-451: The upcoming expedition. Due to its unique features and long tradition of innovation and utility, the Datalink watch line has achieved cult-like status among technically minded people. In addition, many websites are dedicated to the programming and information exchange among its many fans. Yahoo groups also exist for fans and software developers alike, especially for the latest Datalink USB series. The early Datalink 50/150 models received
9000-415: The user was prompted to choose the relevant watch model number. The menu choices were the same for all models. The only differences were the amount of available memory in the watches, and the quantity of phone numbers, appointments, lists etc. which could be downloaded to each model. At the time of their introduction, these watches were known as "PIM" watches, i.e. personal information managers. Bill Gates
9100-470: The user-friendly interface as a personal computer which departed from prior business-oriented systems, and becoming a signature representation of Apple products. In 1985, Commodore released the Amiga 1000 , along with Workbench and Kickstart 1.0 (which contained Intuition ). This interface ran as a separate task, meaning it was very responsive and, unlike other GUIs of the time, it didn't freeze up when
9200-603: The watch. The optical sensor and the method of data transfer were retained. The display of the new series had the same architecture as that of the older models. As with the earlier models, the Triathlon Datalink included dual time zones with local time selectability. Its battery life was approximately three years under normal use. With the advent of portable computers which use active matrix LCD screens which did not refresh like CRT monitors and therefore could not be used for data transfer, in 1997, Timex introduced
9300-463: Was detected by the watch's sensor. Data to be transferred to Datalink watches was held in a database maintained by the Datalink software running on a Windows-based host computer, with alarms, appointments, anniversaries, phone numbers, reminders (or to-do items) being the supported categories of data for transfer. Textual labels for various categories could be up to 15 characters in length, with such text scrolling across an eight character display. Although
9400-432: Was intended to be a lady's watch. The 150 and 150s models are essentially the same, except that the 150s, having a smaller display, has different display addresses from the 150, and thus it needs its own programming code. The programming code is provided in the Timex Datalink software v 2.1 for all models. These watches were programmed using the same software and computer GUI . To download the settings to these early models,
9500-546: Was known as an owner of one, and had also shown the capabilities of the watch on television. The Datalink 150 was also offered as a mail-in gift upon purchase of Office 95 . The model number indicated the maximum number of phone numbers that could be downloaded to the watch. For example, the model 150 could store a maximum of 150 phone numbers if nothing else was stored. Available storage was shared by phone numbers, appointments, anniversaries, lists, wristapps and watch sounds. These models lacked countdown timers or chronographs, but
9600-399: Was later introduced by David Canfield Smith , who had written a thesis on the subject under the guidance of Kay. The PARC GUI employs a pointing device along with a keyboard. These aspects can be emphasized by using the alternative term and acronym for windows, icons, menus, pointing device ( WIMP ). This effort culminated in the 1973 Xerox Alto , the first computer with a GUI, though
9700-588: Was never popular due to its high hardware demands. Nevertheless, it was a crucial influence on the contemporary development of Microsoft Windows . Apple, Digital Research, IBM and Microsoft used many of Xerox's ideas to develop products, and IBM's Common User Access specifications formed the basis of the GUIs used in Microsoft Windows, IBM OS/2 Presentation Manager , and the Unix Motif toolkit and window manager . These ideas evolved to create
9800-488: Was patented in 1949 by Alfred J. Gross . Intended for the use of physicians, there was initial resistance to the idea of being permanently on-call, according to Gross. One of the first practical paging services was launched in 1950 for physicians in the New York City area. Physicians paid US$ 12 per month and carried a 200-gram (7 oz) pager that would receive phone messages within 40 kilometres (25 mi) of
9900-695: Was the first watch/pager able to receive alphanumeric messages. It operates in the 900 MHz band. Beepware also featured FLEX time which, if supported by the service provider, could synchronise the time of the watch with that of the network. It could also automatically adjust to the time zone of the wearer. Pager A pager , also known as a beeper or bleeper , is a wireless telecommunications device that receives and displays alphanumeric or voice messages. One-way pagers can only receive messages, while response pagers and two-way pagers can also acknowledge, reply to, and originate messages using an internal transmitter. Pagers operate as part of
10000-589: Was useful for times when the pager was off or out of the coverage area, as it would know what pages were sent to the subscriber even if the subscriber never actually received the page. Other radio bands used for pagers include the 400 MHz band, the VHF band and the FM commercial broadcast band (88–108&MHz). Other paging protocols used in the VHF, 400 MHz UHF and 900 MHz bands include POCSAG and ERMES. In Canada and
