This coverage map is based on the data that has been confirmed by the test results and computer modeling. Marking of the coverage area cannot insure uninterrupted cellular communications operation in each geographical point. Signal receiving quality depends on the range of essential factors. In order to ascertain the quality of network operation in the concrete geographical point we recommend you to conclude the agreement for a handset rent. Best quality of a wireless signal receiving-transmission is available: outside the buildings, on open area or in the car. Communications or data rate can be impaired depending on housing density and relief. Signal receiving is deteriorated near high-rise buildings, in tunnels, in underground structures- basements and basement-type premises. Temporary communications gap, signal delay or fade can appear as a result of meteors and meteorological changes including a high solar activity and also arise from relief peculiarities that reflect (shield) the wireless signal.
