Adhiparashakthi Arts and Science College,Kalavai.
1.The invention of the microprocessor
2.Digital transform of control link between phone and the cell sides .
3.It was based on FDMA, it allows users to make voice calls within a country.
1.Poor voice quality.
2.Poor battery life.
3.Large phones size.
4.Limited capacity and poor handoff reliability.
The development of 2G cellular system was driven by the need to improved .
5.Data transmission going rapidly.
i.e.LTE is a 4G wireless communications standard developed by the 3rd Generation Partnership Project (3GPP) that's designed to provide up to 10x the speeds of 3G networks for mobile devices such as smartphones, tablets, netbooks, notebooks and wireless hotspots.
Long Term Evolution (LTE) is a radio platform technology that will allow operators to achieve even higher peak throughputs than HSPA+ in higher spectrum bandwidth.
The overall objective for LTE is to provide an extremely high performance radio-access technology that offers full vehicular speed mobility and that can readily coexist with HSPA and earlier networks. Because of scalable bandwidth, operators will be able to easily migrate their networks and users from HSPA to LTE over time.
LTE assumes a full Internet Protocol (IP) network architecture and is designed to support voice in the packet domain.
It has helped to provide the portable internet connection throughout the cities for various devices. It provides DSL cable option to provide to service to miles. It provide telecommunication, IPTV service.
