About TV White Space Research


Tanzania Geo-Location Spectrum Database (T-GLSD) has been generated using the Digital Terrestrial Television (DTT) transmitters information provided by Tanzania Communications Regulatory Authority (TCRA).


T-GLSD is a result of the PhD Research conducted by researcher from College of Informatics and Virual Education of the University of Dodoma. The development of a national geo-location database is a critical step in utilizing unused UHF TV frequency for wireless broadband communication in Tanzania. The role of geo-location spectrum database is to protect DTT users in Tanzania from harmful interference that may be caused due to co-existence with white space devices.


T-GLSD has two main parts, firstly, the implementation of Protocol to Access White-Space (PAWS Protocol) based on IEEE RFC 7545. In the database, the following PAWS Operations have been implemented, namely; initialization, device registration, available spectrum and device validation and secondly, the calculation of available free channel to be shared to WSD and Web user. The calculation of TV White Space is done with a help of Application Programming Interface (API) that connecting to a Calculation Engine (CE) hosted by the Council for Scientific and Industrial Research (CSIR), South Africa.
