PC Magazine (shortened as PCMag ) is an American computer magazine published by Ziff Davis . A print edition was published from 1982 to January 2009. Publication of online editions started in late 1994 and continues as of 2024 .
73-404: The Motorola Razr (pronounced / ˈ r eɪ z ər / like "razor") is a brand of design-oriented mobile phones manufactured by Motorola Mobility (previously Motorola , now a division of Lenovo ). Its current iteration since 2019, styled motorola razr , consist of foldable smartphones reminiscent of the original Razr line of flip phones . The original Razr model (then styled RAZR ),
146-400: A basic mobile phone, which is only capable of voice calling and text messaging. Feature phones and basic mobile phones tend to use a proprietary, custom-designed software and user interface . By contrast, smartphones generally use a mobile operating system that often shares common traits across devices. The critical advantage that modern cellular networks have over predecessor systems is
219-529: A co-founder of Lifeboat Associates financed the magazine in the early stages. The magazine grew beyond the capital required to publish it; to solve this problem, Gold sold the magazine to Ziff-Davis, moving from California to New York City . By February 1983 it was published by PC Communications Corp., a subsidiary of Ziff-Davis Publishing Co., Bunnell and his staff left to form PC World magazine. The first issue of PC carried an interview with Bill Gates , made possible by his friendship with David Bunnell, who
292-434: A customer unit could use. A cellular network mobile phone system gets its name from dividing the service area into many small cells, each with a base station with (for example) a useful range on the order of a kilometer (mile). These systems have dozens or hundreds of possible channels allocated to them. When a subscriber is using a given channel for a telephone connection, that frequency is unavailable for other customers in
365-418: A few sets of radio channels (frequencies). Once these few channels were in use by customers, no further customers could be served until another user vacated a channel. It would be impractical to give every customer a unique channel since there would not be enough bandwidth allocated to the mobile service. As well, technical limitations such as antenna efficiency and receiver design limit the range of frequencies
438-523: A mobile device, such as a smartphone. The term "app" is a shortening of the term "software application". A common data application on mobile phones is Short Message Service (SMS) text messaging. The first SMS message was sent from a computer to a mobile phone in 1992 in the UK while the first person-to-person SMS from phone to phone was sent in Finland in 1993. The first mobile news service, delivered via SMS,
511-401: A number of distinguishing features. The International Telecommunication Union measures those with Internet connection, which it calls Active Mobile-Broadband subscriptions (which includes tablets, etc.). In the developed world, smartphones have now overtaken the usage of earlier mobile systems. However, in the developing world, they account for around 50% of mobile telephony . Feature phone
584-501: A problem due to the design of the phone, the quality of the cellular network and compression algorithms used in long-distance calls . Audio quality can be improved using a VoIP application over WiFi . Cellphones have small speakers so that the user can use a speakerphone feature and talk to a person on the phone without holding it to their ear. The small speakers can also be used to listen to digital audio files of music or speech or watch videos with an audio component, without holding
657-670: A result of the Motorola split. The Razr brand returned in 2011 with the introduction of the Motorola Droid Razr smartphone (the "Droid" name only used by Verizon in the USA). The line shared its trademark thinness and stylized tapered corners with the original. The line included: The Droid Razr HD and Droid Razr M were succeeded by the Droid MAXX and Droid Mini respectively. In November 2019, Motorola Mobility revived
730-464: A single hand, since most thumbs cannot reach the entire screen surface; they may need to be shifted around in the hand, held in one hand and manipulated by the other, or used in place with both hands. Due to design advances, some modern smartphones with large screen sizes and "edge-to-edge" designs have compact builds that improve their ergonomics, while the shift to taller aspect ratios have resulted in phones that have larger screen sizes whilst maintaining
803-517: A single platform. There are a huge variety of apps, including video games , music products and business tools. Up until that point, smartphone application distribution depended on third-party sources providing applications for multiple platforms, such as GetJar , Handango , Handmark , and PocketGear . Following the success of the App Store, other smartphone manufacturers launched application stores, such as Google's Android Market (later renamed to

The SIM card is approximately the size of a small postage stamp and is usually placed underneath the battery in the rear of the unit. The SIM securely stores the service-subscriber key (IMSI) and the K i used to identify and authenticate the user of the mobile phone. The SIM card allows users to change phones by simply removing
949-546: A telephone service area, as opposed to a fixed-location phone ( landline phone ). The radio frequency link establishes a connection to the switching systems of a mobile phone operator , which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture, and therefore mobile telephones are called cellphones (or "cell phones") in North America. In addition to telephony , digital mobile phones support
1022-471: A telephone service area, which is divided up into 'cells'. Each cell uses a different set of frequencies from neighboring cells, and will typically be covered by three towers placed at different locations. The cell towers are usually interconnected to each other and the phone network and the internet by wired connections. Due to bandwidth limitations each cell will have a maximum number of cell phones it can handle at once. The cells are therefore sized depending on
1095-652: A variety of other services , such as text messaging , multimedia messaging , email , Internet access (via LTE , 5G NR or Wi-Fi ), short-range wireless communications ( infrared , Bluetooth ), satellite access ( navigation , messaging connectivity ), business applications, payments (via NFC ), multimedia playback and streaming ( radio , television ), digital photography , and video games . Mobile phones offering only basic capabilities are known as feature phones ( slang : "dumbphones" ); mobile phones that offer greatly advanced computing capabilities are referred to as smartphones . The first handheld mobile phone
1168-469: A very thin carbon microphone". Early predecessors of cellular phones included analog radio communications from ships and trains. The race to create truly portable telephone devices began after World War II, with developments taking place in many countries. The advances in mobile telephony have been traced in successive "generations", starting with the early zeroth-generation ( 0G ) services, such as Bell System 's Mobile Telephone Service and its successor,
1241-412: Is a term typically used as a retronym to describe mobile phones which are limited in capabilities in contrast to a modern smartphone . Feature phones typically provide voice calling and text messaging functionality, in addition to basic multimedia and Internet capabilities, and other services offered by the user's wireless service provider . A feature phone has additional functions over and above

The movements of a mobile phone user can be tracked by their service provider and, if desired, by law enforcement agencies and their governments. Both the SIM card and the handset can be tracked. China has proposed using this technology to track
1387-468: The 5G NR (5G New Radio) standard. 5G can be implemented in low-band, mid-band or high-band millimeter-wave, with download speeds that can achieve gigabit-per-second (Gbit/s) range, aiming for a network latency of 1 ms. This near-real-time responsiveness and improved overall data performance are crucial for applications like online gaming , augmented and virtual reality , autonomous vehicles , IoT, and critical communication services. Smartphones have
1460-648: The Improved Mobile Telephone Service . These 0G systems were not cellular , supported a few simultaneous calls, and were very expensive. The first handheld cellular mobile phone was demonstrated by John F. Mitchell and Martin Cooper of Motorola in 1973, using a handset weighing 2 kilograms (4.4 lb). The first commercial automated cellular network ( 1G ) analog was launched in Japan by Nippon Telegraph and Telephone in 1979. This

Mobile payments were first trialled in Finland in 1998 when two Coca-Cola vending machines in Espoo were enabled to work with SMS payments. Eventually, the idea spread and in 1999, the Philippines launched the country's first commercial mobile payments systems with mobile operators Globe and Smart . Some mobile phones can make mobile payments via direct mobile billing schemes, or through contactless payments if
1679-540: The Razr V3 , was a flip phone released in 2004 with a remarkably thin and fashionable look. It became extremely popular, leading to the release of a variety of different Razr models. The line was succeeded by the Motorola Razr2 flip phones in 2007. The Razr later evolved into a line of non-flip devices in 2011, Droid Razr (known simply as the "Motorola RAZR" on non-Verizon networks), bearing design similarities to
1752-649: The WCDMA standard. This was followed by 3.5G or 3G+ enhancements based on the high-speed packet access (HSPA) family, allowing UMTS networks to have higher data transfer speeds and capacity. 3G is able to provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. This ensures it can be applied to mobile Internet access, VoIP , video calls, and sending large e-mail messages, as well as watching videos, typically in standard-definition quality. By 2009, it had become clear that, at some point, 3G networks would be overwhelmed by
1825-450: The internet of things (IoT), fixed wireless access , and multimedia streaming (including music, video, radio , and television ). Deployment of fifth-generation ( 5G ) cellular networks commenced worldwide in 2019. The term "5G" was originally used in research papers and projects to denote the next major phase in mobile telecommunication standards beyond the 4G / IMT-Advanced standards. The 3GPP defines 5G as any system that adheres to
1898-599: The screen . Depending on the device's type and design, the screen fills most or nearly all of the space on a device's front surface. Many smartphone displays have an aspect ratio of 16:9 , but taller aspect ratios became more common in 2017. Screen sizes are often measured in diagonal inches or millimeters ; feature phones generally have screen sizes below 90 millimetres (3.5 in). Phones with screens larger than 130 millimetres (5.2 in) are often called " phablets ." Smartphones with screens over 115 millimetres (4.5 in) in size are commonly difficult to use with only
1971-530: The 1980s, PC Magazine gave significant coverage to programming for the IBM PC and compatibles in languages such as Turbo Pascal , BASIC , Assembly and C . Charles Petzold was one of the notable writers on programming topics. Editor Bill Machrone wrote in 1985, that If an article doesn't evaluate products or enhance productivity, "chances are it doesn't belong in PC Magazine ". In an early review of
2044-595: The GSM was used by over 5 billion people in over 220 countries. The GSM (2G) has evolved into 3G, 4G and 5G. The standardization body for GSM started at the CEPT Working Group GSM (Group Special Mobile) in 1982 under the umbrella of CEPT. In 1988, ETSI was established, and all CEPT standardization activities were transferred to ETSI. Working Group GSM became Technical Committee GSM. In 1991, it became Technical Committee SMG (Special Mobile Group) when ETSI tasked

Kenya's M-PESA mobile banking service, for example, allows customers of the mobile phone operator Safaricom to hold cash balances which are recorded on their SIM cards. Cash can be deposited or withdrawn from M-PESA accounts at Safaricom retail outlets located throughout the country and can be transferred electronically from person to person and used to pay bills to companies. Branchless banking has also been successful in South Africa and
2628-550: The abnormally high traffic. Capacity was further increased when phone companies implemented digital networks. With digital, one frequency can host multiple simultaneous calls. Additionally, short-range Wi-Fi infrastructure is often used by smartphones as much as possible as it offloads traffic from cell networks on to local area networks. The common components found on all mobile phones are: Low-end mobile phones are often referred to as feature phones and offer basic telephony. Handsets with more advanced computing ability through
2701-961: The benefits of different calling plans. For example, a particular plan might provide for cheaper local calls, long-distance calls, international calls, or roaming. The mobile phone has been used in a variety of diverse contexts in society. For example: In 1998, one of the first examples of distributing and selling media content through the mobile phone was the sale of ringtones by Radiolinja in Finland. Soon afterwards, other media content appeared, such as news, video games, jokes, horoscopes, TV content and advertising. Most early content for mobile phones tended to be copies of legacy media , such as banner advertisements or TV news highlight video clips. Recently, unique content for mobile phones has been emerging, from ringtones and ringback tones to mobisodes , video content that has been produced exclusively for mobile phones. In many countries, mobile phones are used to provide mobile banking services, which may include
2774-469: The call, from detecting the presence of a handset in a service area, temporary assignment of a channel to a handset making a call, interface with the land-line side of the network to connect to other subscribers, and collection of billing information for the service. The automation systems can control the "hand off" of a customer handset moving between one cell and another so that a call in progress continues without interruption, changing channels if required. In

3066-435: The concept of frequency reuse allowing many simultaneous telephone conversations in a given service area. This allows efficient use of the limited radio spectrum allocated to mobile services, and lets thousands of subscribers converse at the same time within a given geographic area. Former systems would cover a service area with one or two powerful base stations with a range of up to tens of kilometers' (miles), using only
3139-415: The earliest mobile phone systems by contrast, all control was done manually; the customer would search for an unoccupied channel and speak to a mobile operator to request connection of a call to a landline number or another mobile. At the termination of the call the mobile operator would manually record the billing information. Mobile phones communicate with cell towers that are placed to give coverage across
3212-496: The end of 2009. In 2014, there were more than seven billion mobile phone subscribers worldwide, a number that is expected to keep growing. Mobile phones are used for a variety of purposes, such as keeping in touch with family members, for conducting business, and in order to have access to a telephone in the event of an emergency. Some people carry more than one mobile phone for different purposes, such as for business and personal use. Multiple SIM cards may be used to take advantage of
