Increased demand of consumers on services in the mobile environment with high data rate and technologically developed mobile broadband communication systems (IMT) will require more spectrum to be available in the future. The new technologies as well as the existing services require frequencies for their development. The 694-790 MHz (700 MHz) band was allocated by World Radiocommunication Conference 2012 (WRC-12) in ITU Region 1, which includes also Europe, to the mobile service on a co-primary basis with other services to which this band is allocated on a primary basis (broadcasting etc.) and was identified for IMT. The allocation is effective immediately after WRC-15. 700 MHz band can be putted into use for land mobile service only when all necessary electromagnetic compatibility, frequency sharing studies are completed and technical conditions of use of frequencies determined. In the framework of the research a particular attention will be paid to the evaluation of perspective use of the 700 MHz band by land mobile service in Latvia.
