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.
