• 3G wireless technology represents the convergence of various 2G wireless telecommunications systems into a single global systems that includes both terrestrial and satellite components• Fourth generation(4G) mobile systems focus on seamlessly integrating the existing

wireless technologies including GSM, wireless LAN, and Bluetooth.

This contrasts with third generation (3G), which merely focuses on developing new

standards and hardware. 4G systems will support comprehensive and personalized

services providing stable system performance and quality service.





M2M COMMUNICATIONS


Applications of 3G

• Mobile T V-Usually means television watched on a small handheld device • Audio or video on demand-are systems which allow users to select and watch/listen audio or video

content on demand• Video Conferencing-Is a conduct of video conference which allow 2 or more locations to interact via

two-way video and audio transmission simultaneously• Location Based Service-Is an information or entertainment service accessible with mobile devices

through mobile network and utilizing the ability to make use of geographical position of mobile device





M2M COMMUNICATIONS


What is 4G?• 4G takes on a number of equally true definitions.

In Simplest terms 4G is the next generation of wireless networks

that will replace 3G network sometimes in future.4G is simply an

initiative by academics R&D labs to move beyond the limitations and

problems of 3G which is having trouble getting deployed and meeting

its promised performance and throughput

Strength• Faster Data Transmission and higher bit rate and bandwidth, allow

more business applications and commercialization

Weakness• No large user community for advanced mobile data applications yet• Not possible to offer full internet experience due to limited speed

and Bandwidth
