With 3G spectrum auctions on the anvil, the issue of technological innovations and improvisations has become critical. At present, 2G operators face issues relating to call drops and low quality of service. They also face a huge pent-up demand for voice-based services. In addition, India has chosen a slightly different model for 3G compared to the rest of the world. While elsewhere 15-20 MHz spectrum has been allocated for the rollout of 3G services, India will have only 5 MHz. Therefore, Indian operators are likely to focus their attention primarily on using the allocated 3G spectrum to fill the demand for voice capacity.
