3G Architecture & Network

It is a NEW radio interface.Data should be Transfer in Packets.UMTS(universal mobile telecommunication system)3G network is upgraded feature of GSM & GPRS.Wireless LAN need not be connected to the GPRS Backbone But could also both packet switch directly to an IP network.UMTS has both PS(packet switch) and CS(Circuit switch).

UMTS NETWORK

Call ControlThere are two types of calla) MO(mobile originated) b) MT(Mobile Terminated) Mo call, Exchange of signaling takes place MS In Packet switching data are transfers

from source to destination in one session.

Radio Access Networks

WCDMA(wideband code division Multiple Access) uses 2Ghz Frequency band and it can reaches data transfer speed up to 2Mb/s.WLAN technology gives transfer rate of 25Mb/s to user. It uses 5Ghz frequency band and the Services range around 150m to 300m.

Radio Network Function

a)Transfer of user data.b)Radio Resources Management c) Security Function d)Broadcast servicee)Power Control

Advantage of 3GNew radio spectrum to relieve overcrowding in existing systems.More bandwidth, security and reliability. Interoperability between service providers.Fixed and variable data rates.Backward compatibility of devices with existing networks.

Disadvantage of 3G

The cost of upgrading base station and cellular infrastructure to 3G is likely to be very high. Requires different handsets and there is the issue of handset availability. 3G handsets will be a complex .
