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
