ISSUES HAMPERING ITS GROWTH

High spectrum licensing fees for the 3G services

Huge capital required to build infrastructure for 3G services.

Health impact because of electromagnetic waves.

Prices are very high for 3G mobile services. Will 2G users switch to 3G services?

Takes time to catch up as the service is new.

VARIOUS SERVICES THAT 3G (W-CDMA) COULD

PROVIDE:

3G eases the machine to machine communication in the near future

For Example: Refrigerator with in-built sensors, sensing the emptied shelves and

sending messages automatically to the PDA of the user or the local store to refill

it.

CONCLUSION

3G services will add invaluable dimension for the integral part of the modern

world

In the near future, Mobility will not be considered as an add-on: it will

become a fundamental aspect

Development of 3G networks will continue and pick up pace in the near

future
