3G is a third generation wireless network technology that provides high-speed bandwidth for multimedia services combining voice and data. It can provide internet access at speeds up to 2Mbps for stationary devices and 384kbps for fast moving devices, allowing for services like email with full file attachments. The 3G network architecture includes a core network and access network connected to user equipment. It uses technologies like UMTS and WCDMA to transfer both packet-switched and circuit-switched data and provide services across different networks and service providers.

2. 3G is next generation wireless network technology.

4. 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).

8. There are two types of call
a) 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.

9. 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.

11. New 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.

12. 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 .
