Embodiment Construction

[0022] The present invention proposes an optimization method for an indoor wireless communication system. The indoor wireless communication system has only antennas and feeders indoors, without other active and passive communication devices. Each antenna is connected to the shaft of the building through an independent feeder. , connected to the communication source through various communication devices in the shaft, that is, all active and passive communication devices are concentrated in the shaft.

[0023] Such as figure 1 As shown, in a preferred embodiment, the present invention includes the following implementation steps:

[0024] Step S1, according to the power loss value of each antenna (including the feeder) and the preset loss threshold, determine the first-level communication device connected to each antenna.

[0025] combine figure 2 As shown, five antennas A1~A5 (the output powers corresponding to antennas A1~A5 are respectively P11~P15, and the power loss value...

Abstract

The invention discloses an optimizing method for an indoor wireless communication system. The method comprises the following steps: determining first-step communication devices which are connected with each antennae according to the power loss value and the preset loss threshold value of each antenna; successively determining each communication device from the first step to the highest step by using first-step communication devices as a computing base; calculating the output power of each antenna from the first step to the highest step according to the principle that the input power of the present-step communication device is equal to the difference between the output power and the power loss of the communication device with the lower step and using the design power P0 of a communication information source as a calculating base; calculating the average value Pm of the output power of the antennae and the power difference value delta of the antennae, and calculating the optimizing output power P'0 of the communication information source. Through the adoption of the method disclosed by the invention, selecting reasonable communication devices and the power of the information source can be ensured, the automatic performance of the networking of the wireless communication system is improved, the networking efficiency is improved, and the networking construction difficulty is simplified.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to an optimization method for an indoor wireless communication system. Background technique [0002] Due to the complex structure of the room, the shielding and absorption of the building itself has caused a large transmission attenuation of radio waves, forming a weak field strength area or even a blind area of ​​the mobile wireless communication signal, resulting in the first and second floors of the basement of the building. Weak, and even some blind spots. Moreover, due to poor indoor coverage, it is easy for the communication terminal to "drop the network", and even cause no response to paging, and the user is not in the service area. [0003] Therefore, for indoor user groups, in order to improve the mobile communication environment in buildings, including solving the blind area coverage and signal extension of indoor wireless communication signals, and improving the...
