Available, too, was a snug-fitting zippered leather case which covered the entire body of the phone and had a clear plastic front to make the user interface accessible. It featured a sturdy spring-steel belt clip and a small cutaway at the top to allow the antenna to protrude. Charging could still be performed with the cover on, but change of battery required its removal. DynaTAC relates to US phones used on
511-434: 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
584-418: 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
657-523: 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,

Meilahn placed the first commercial wireless call on a DynaTAC from his 1983 Mercedes-Benz 380SL to Bob Barnett, former president of Ameritech Mobile Communications , who then placed
1241-471: 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
1314-401: A term later applied to other brands as a contrast to smaller handsets appearing in the 1990s. While it might be considered extremely unwieldy by modern standards, at the time it was considered revolutionary because mobile telephones were bulky affairs installed in vehicles or in heavy briefcases.

3066-961: 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
3139-469: 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

4818-655: The time of the Motorola StarTAC 's release in 1996, it was obsolete. The first cellular phone was the culmination of efforts begun at Bell Labs , which first proposed the idea of a cellular system in 1947, and continued to petition the Federal Communications Commission (FCC) for channels through the 1950s and 1960s, and research conducted at Motorola . In 1960, electrical engineer John F. Mitchell became Motorola's chief engineer for its mobile communication products. Mitchell oversaw
4891-699: The use of native software applications are known as smartphones . The first GSM phones and many feature phones had NOR flash memory, from which processor instructions could be executed directly in an execute in place architecture and allowed for short boot times. With smartphones, NAND flash memory was adopted as it has larger storage capacities and lower costs, but causes longer boot times because instructions cannot be executed from it directly, and must be copied to RAM memory first before execution. Mobile phones have central processing units (CPUs), similar to those in computers, but optimised to operate in low power environments. Mobile CPU performance depends not only on
