PageNet. PageNet , also known as Paging Network, Inc., was founded in 1981 by entrepreneur George Perrin and ceased in 1999. The company grew to become the largest wireless messaging company in the world, with more than 10 million pagers in service, and $1 billion in revenues, before the paging industry's rapid decline in the late 1990s.
Pager. A pager, also known as a beeper or bleeper, [1] 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. [2]
v. t. e. A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver (typically three cell sites or base transceiver stations ). These base stations provide the cell with ...
A cell site, cell phone tower, cell base tower, or cellular base station is a cellular -enabled mobile device site where antennas and electronic communications equipment are placed (typically on a radio mast, tower, or other raised structure) to create a cell, or adjacent cells, in a cellular network. The raised structure typically supports ...
This is the case in both GSM and IS-136 for example. Exceptions to this include the DECT and Personal Handy-phone System (PHS) micro-cellular systems, UMTS-TDD UMTS variant, and China's TD-SCDMA, which use time-division duplexing, where different time slots are allocated for the base station and handsets on the same frequency.
Each day the number of mobile devices is increasing, mobile architecture is the pieces of technology needed to create a rich, connected user experience. Currently, there is a lack of uniform interoperability plans and implementation. There is a lack of common industry view on the architectural framework. This increases costs and slows down 3rd ...

NMT was the first mobile phone network to feature international roaming. In 1983, the first 1G cellular network launched in the United States, which was Chicago-based Ameritech using the Motorola DynaTAC mobile phone. In the early to mid 1990s, 1G was superseded by newer 2G (second generation) cellular technologies such as GSM and cdmaOne.
