However, GSM is quite rigid in its resource allocation: a user is assigned one frequency bucket at the start of the session and he gets to send messages within that frequency bucket once in every eight time slots. Further, the allocation is frozen at the beginning of the session and remains fixed throughout the session.

How Technology Neutrality Pose Tisk to 3G / BWA Spectrum Holders ?

by

In India, the government has allocated 2100 MHz and 2300 MHz spectrum bands for 3G and BWA (4G) services, respectively.
