...capability to perform many different functions. When it comes to cell phones there are two major networks available, 3G and 4G. The "G" stands for a generation of mobile technology, installed in phones and on cellular networks. Each "G" generally requires you to get a new phone, and for networks to make expensive upgrades. The first two were analog cell phones (1G) and digital phones (2G).(Segan, 2013) Third-generation mobile networks, or 3G, came to the U.S. in 2003. With minimum consistent Internet speeds of 144Kbps, 3G was supposed to bring "mobile broadband." There are now so many varieties of 3G that a 3G connection can get you Internet speeds anywhere from 400Kbps to more than ten times that. (Segan, 2013) While most of us are used to getting high speed Internet connections at home, the office or even the local coffee shop, once we are on the road those high speeds have to stay behind. With 4G the promise is that you can get real mobile broadband to go. (Vilches, 2010) There are two fundamental aspects of LTE. The first is that the technology finally leaves behind the circuit switched network of its GSM roots and moves to an all-IP flat networking architecture. This is a significant shift which in very simple terms means that LTE will treat everything it transmits, even voice, as data. The other big change relates to the use of MIMO technology, or multiple antennas at both the transmitter and receiver end to improve communication performance. This setup can either be...

...Wireless Networks 4G Wireless Networks Britney Green CIS 500: Information Systems for Decision Making Professor Frank Lazzara November 4, 2012 4G Wireless Networks “Wireless networks use packet switching and wireless networks. Patching switching is when the path of the signal is digital and is neither dedicated nor exclusive. Routers are devices that forward packets from one network to another network. Packets occur when the network breaks a file or e-mail message into smaller blocks of specific size. Wireless routers are actually wired routers with wireless access points (WAP) built in. It provides both wired and wireless at the same time”. (Turban & Volonino, 2011) Third generation also called 3G; of cellular telecommunications technology supports multimedia and broadband services. Broadband means fast transmission speed. It is faster than the 1G and 2G. The third generation networks have far greater ranges because they use large satellite connections that connect to telecommunication towers. The fourth generation is called 4G. 4G mobile network standards enable faster data transfer rates. (Turban & Volonino) Right now 4G is the latest generation of wireless data technologies. It carries average download rates of 3 Mbps or more. “In contrast, today's 3G networks typically deliver average download speeds about one-tenth of that rate. The 2G and 3G started separately with their own purposes; soon both will be converted to the 4G network” (Turban...
