Migration from 2G to 3G - Options: Evolution of Mobile Technologies: The Migration Path This is a brief overview of what has been already done and possible expected migration path of mobile operators. At the 2G phase, there were three major dominant systems in market: a) GSM operating in 900, 1800 and 1900MHz band, b) TDMA operating in 800MHz, 1900MHz and 850MHz (North America), and c) CDMA (IS-95) operating in 1900 and 800MHz band. 2G systems offered enhanced voice services and improved

technologies will be examined. More importantly, it will trace the route taken by the mobile network from 2G to 3G and beyond, it will look at the factors that have influenced the decision of mobile operators to switch or upgrade to 3G and also why some others have chosen not to do so. While technology has evolved, so has the business models of the industry. The evolution of the business models from 2G to 3G will be described here. How the mobile industry has changed in terms of market players is part of this

3G, 3.5G, 3.75G... oh, and 2.75G, too In addition to the aforementioned speed requirements, the ITU's official 3G specification also called out that compatible technologies should offer smooth migration paths from 2G networks. To that end, a standard called UMTS rose to the top as the 3G choice for GSM operators, and CDMA2000 came about as the backward-compatible successor to IS-95. Following the precedent set by GPRS, CDMA2000 offered CDMA networks an "always-on" data connection in the form

them to check their emails or surf the web. Currently, there are two different wireless networks: 3G and 4G. 3G or 3rd generation mobile telecommunication is pretty much an application service that includes wide-area wireless voice telephone, mobile internet access, video calls, and mobile TV, all in a mobile environment. 4G is pretty much the same concept as 3G except it’s ten times faster than 3G. (Lee, 2011). Smartphone users are now consuming more data than ever before on a per-user basis

MOBILE COMPUTING ASSIGNMENT NAME: SOPHIA EHINOMEN ATIVIE MATRIC NO: 2010/1336 DEPT: INFORMATION TECHNOLOGY 1. CDMA (CODE DIVISION MULTIPLE ACCESS). CDMA (Code-Division Multiple Access) is a channel access method used by various radio communication technologies. It is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth. The technology is used in ultra-high-frequency (UHF) cellular telephone systems in the

Authentication Center (AUC) and Equipment Identity Register (EIR). The last segment is the GPRS Core Network, which consists of Serving GPRS Support Node (SGSN) and Gateway GPRS Support Node (GGSN). All GSM operators more or less, have these common elements for its 2G/2.5G networks. Difference between 2G and 3G The basic difference between 2G and 3G networks is the Radio Network Controller (RNC), which works for 3G as the BSC of 2G, and the Node B, which works as the BTS. Compared to GSM, UMTS

3G Unit-1: GPRS & EDGE General Packet Radio Service (GPRS) General Packet Radio Service (GPRS) is a mobile data service available to users of GSM mobile phones. It is often described as "2.5G", that is, a technology between the second (2G) and third (3G) generations of mobile telephony. It provides moderate speed data transfer, by using unused TDMA channels in the GSM network. Originally there was some thought to extend GPRS to cover other standards, but instead those networks are being converted

------------------------------------------------- Technical overview See also: S Core NetworkGPR 2.5G and 3G systems rely on double core network infrastructures; traditional circuit-switched network nodes (switching points) for telephony, and packet-switched GPRS nodes for various data services. Dedicated nodes handle the SMS service. 4G systems are expected to be all-IP, meaning that the core network is based on IP routers.[citation needed] [edit]Services offered GPRS extends the GSM Packet circuit switched data capabilities and makes
