FIELD: physics, communication. ^ SUBSTANCE: invention concerns field of communication and can be used in portable honeycomb system with sectorized cells. The spatial diversity or a polarisation diversity is provided by means of maintenance at least two branches (A, B). According to the invention the frequency band of the functional is parted on set of frequency bands for transmission and reception (TX frequency bands and RX frequency bands). All sectors (S1, S2, S3) are united in the form of branches in corresponding installed on a mast the amplifier (TMA). TX signals within TX the frequency bands belonging TMA diplexed and simultaneously transmitted on sectors (S1-S3). The radio-frequency signals (RF-signals) accepted on one branch of sector, unite with the Rch-signals accepted on corresponding sector in other branches. United thus RX signals move to base radio station on a unique feeder together with TX the signals submitted in an opposite direction from transceivers (TRX) of base station besides most TMA. To sector can be appointed two or the several TX frequencies. The abrupt reorganisation of frequency within everyone TX frequency bands (fusionable abrupt reorganisation of frequency) can be for choice provided. ^ EFFECT: simplification by reduction of number of feeders between base station and the device of a diversity of antennas. ^ 18 cl, 22 dwg |
