Limitations of 3GLimitations of 3G

Projected data rate of 3G is 2Mbps.

Actual data rate is from few b/s to few Kbps.Also these depends on user activities.less coverage area.It is difficult to provide a full range of multirate

services all with different QoS andperformance requirement.

Integration between different network is also notpossible at same QoS .

ConclusionConclusion

iBurst is definitely going to be the future of our communicationsystem which is going to remove most of the hap hazards thatare present today with a definite and rise in data transferring

rate and also the security of the data and removes the saturationin communication and will revolutionize the communicationsystem.
