Issues On 3G Wireless SystemIssues On 3G Wireless SystemIssues On 3G Wireless SystemIssues On 3G Wireless System
High input fees for the 3G service licenses. Great differences in the licensing terms. Current high debt of many telecommunication companies,
making it more of a challenge to build the necessaryinfrastructure for 3G.
Health aspects of the effects of electromagnetic waves. Expense and bulk of 3G phones. Lack of coverage because it is still a new service. High prices of 3G mobile services in some countries.

4G is a research item for next-generation wide-area cellular radio,where you have 1G, 2G, 3G and then 4G [and 5G].
4G is a conceptual framework and a discussion point to address futureneeds of a high speed wireless network.
It offers both cellular and broadband multimedia services everywhere. Expected to emerge around 2010 2015.
4G should be able to provide very smooth global roaming ubiquitouslywith lower cost. Theoretically, 4G is set to deliver 100 Mbps to a roaming mobile device
globally, and up to 1 Gbps to a stationary device. With this in mind, itallows for video conferencing, streaming picture perfect video (i.e.telemedicine, tele-geo processing application etc.)

CONCLUSIONCONCLUSIONCONCLUSIONCONCLUSION
4G technology is projecting towards a single globalstandard that can be embraced worldwide with integrationwith the help of IPV 6.
It will provide REAL WIRELESS WORLD. Future 4G wireless networks will need to support diverse
IP multimedia applications to allow sharing of resourcesamong multiple users.
It promises to fulfill the goal of personal computing andcommunication providing higher data rates everywhereover a wireless network.
4G is expected to be launched by 2012.
