EMC problems of GSM 1800 cellular networks and radio relay systems of the fixed service in Russia

The paper deals with EMC problems of GSM 1800 cellular networks and radio relay systems in the 2 GHz band in Russia. The EMC analysis of GSM 1800 cellular networks and radio relay systems is developed on the basis of empirical-statistical model of radio waves propagation in urban areas. Putting into consideration the power and spatial parameters the required separation distances and frequency offsets between radio electronic devices of the mentioned systems are defined.
