Embodiment Construction

[0016] The present invention will be described in further detail below through specific embodiments and in conjunction with the drawings.

[0017] The working method of this intelligent repeater is developed based on the protocol RCR-STD-28 of the PHS communication system. The main technical problems to be solved are: a. Coverage of PHS system indoor weak signal areas and blind areas; b. Amplified wireless There are few channels; c. Solve the problem of separate design of receiving and transmitting antennas, so that the indoor coverage antenna 2 can be placed flexibly; d. Solve the problem that the power is too small to cover a large area;

[0018] The method for solving the above-mentioned problem is: a, the intelligent base station signal relay amplification and forwarding device selects separate donor antenna 1 and coverage antenna 2, and they are respectively connected with the base station and the terminal through the relay amplifier circuit and the switch circuit 3. In t...

Abstract

The present invention is intelligent base station signal relay amplifying and transmitting device and method. The intelligent base station signal relay amplifying and transmitting device has separated donor antenna and covering antenna contacting with the base station and terminals separately and connected via relay amplifying circuit and switching circuit. The separated design of receiving antenna and the transmitting antenna makes the covering antenna capable of being installed in different position for flexible covering mode, reasonable signal covering and covering complicated area. The separated antennas have reduced interference and this makes it possible to select ever high antenna gain and raise the signal utilization. In addition, the frequency with weakest field strength is used as the frequency for the regenerating time interval in the signal relay amplifying and transmitting device for the intelligent base station, further reducting the one frequency interference to the base station.

Description

Technical field: [0001] The invention relates to an intelligent base station signal relay amplification and forwarding device and method, and the relay amplification and forwarding device can also be referred to as "intelligent repeater". Background technique: [0002] The PHS communication system is a mobile communication system that China Telecom is vigorously building now. Its working mode is TDMA / TDD, and the frequency used is 1893.65-1919.45MHz. Due to the high frequency used, the diffraction ability of the signal is very poor, and the transmission power of the base station is small, which makes it difficult for the signal to penetrate the wall and cover the room. The indoor signal is generally weak, there are many blind spots, and the call quality of indoor users is poor. The station is the most economical and practical way to solve indoor coverage and remote suburban areas. However, the existing intelligent repeater has low power, and the receiving and transmitting an...
