The principles of creation of distributed system of communication in which as the trunk channel the space communication link is involved, and as system of subscriber access - a broadband radio access in the range 300-450 MHz are considered. Assessment of a possibility of creation and deployment of a similar communication system for the territories in which use of alternative technologies is poor-selling or impossible is carried out. The technology of the experimental assessment of quality of the provided services on the basis of the measurements executed by means of a set of the equipment consisting of the exchange service station of system of a radio access, the personal computer and the receiver of system of satellite navigation is offered. Spectral characteristics of signals when rendering different types of services are received and are given. Requirements to parameters of the space radio bridge by means ofwhich remote BS are connected to a kernel of system are formulated...
