Vygivskiy R. Increase of quality indices for WiMax base station

Object of investigation is the WiMax base station of the access network. Subject of investigation is multi-flight radio-relay line intended to extend the coverage area of the base station and to improve quality indices. Research activity related to the increase of quality indices of the WiMax base station by the increase of the coverage area due to an application of multiflight radio-relay links and at the expense of criterion optimization for the choice of the direction of Smart-aerials radiation to operate on the border of coverage area of the WiMax base station of the WiMax technology is conducted. Effect of increasing the number of flights of the radio-relay links is analyzed; power calculations of inter-channel interference for different numbers of sub-channels in the OFDM signal structure are produced. The coverage area of the WiMax base station is extended without any use of wired connections that reduces the cost and time of deployment time of access network. As a result of implementation of dissertation work the area of maintenance of the base station WiMax without the use of some wire connections is megascopic, that in the turn considerably reduces a cost and time of development of network of access. An absolutely new criterion for Smart aerials beam pointing using the modulation type detector is proposed. An application domain is the system of telecommunications.
