Abstract

This thesis considers the problem of utilizing available TV White Space (TVWS) in the TV UHF band (470-698 MHz) for offering broadband wireless access to both urban and rural population in India. Doordarshan (DD) claims to currently use this band for analog TV terrestrial transmission and is starting to use it for Digital TV terrestrial transmission (DTT). However, DD has only 1415 analog transmit- ters throughout the country and only a few digital transmitters. The 200-plus MHz band is barely used in most parts of the country. DD's ultimate require- ments are for use of 6 channels of 8 MHz each (48MHz) for Digital TV broadcast in each location. In each of the 8 MHz band, DTT can have 10 or more channels, implying that DD is planning 60-plus DTT channels. Nevertheless, considering DDs requirements of 48 MHz at each location, close to 100 MHz spectrum may be available in the TVWS band for secondary usage at most locations.
