List Of Wireless Network Technologies
__NOTOC__ This is a list of generations of wireless network technologies in mobile telecommunications. ''*'' latest and optimal iteration of technology ''**'' originally not considered 4G, only after a revision of 4G specification 0G 0G systems did not use cellular systems. Referred to as ''pre-cellular'' (or sometimes ''zero generation'', that is, '' 0G mobile'') systems. 1G 1G or (1-G) refers to the first generation of cellular network technology. These are the analog telecommunication standards that were introduced in 1979 and the early to mid-1980s and continued until being replaced by 2G digital telecommunications. The main difference between these two mobile telephone generations is that in 1G systems the audio was encoded as analog radio signals (though call set-up and other network communications were digital), while 2G networks were entirely digital. 1.5G 2G 2G (or 2-G) provides three primary benefits over their predecessors: phone conversations are digital ...

Mobile Telecommunications
Mobile telephony is the provision of wireless Telephony, telephone services to Mobile phone, mobile phones, distinguishing it from fixed-location telephony provided via landline phones. Traditionally, telephony specifically refers to Telephone call, voice communication, though the distinction has become less clear with the integration of additional features such as text messaging and Internet, data services. Modern mobile phones connect to a terrestrial cellular network of Base station, base stations (commonly referred to as Cell site, cell sites), using Radio wave, radio waves to facilitate communication. Satellite phone, Satellite phones use wireless links to orbiting Communications satellite, satellites, providing an alternative in areas lacking local terrestrial communication infrastructure, such as landline and cellular networks. Cellular networks, satellite networks, and landline systems are all linked to the public switched telephone network (PSTN), enabling calls to be ...
