摘要
论证了仅采用一套集约化室内综合无线覆盖系统设计,选取符合参数要求定制的器件,可以实现一套覆盖系统对无线信号从400MHz到2500MHz频率范围全覆盖。通过对室内多路无线信号源进行合路时的杂散干扰、接收机阻塞干扰、互调干扰的分析,以及对泄漏和信号切换的分析,给出了无线合路设备等关键器件的参数选择,为无线合路设备POI(point of interface)、滤波器的选取提供了选型依据。
The study has proved that using one intensive inner building wireless coverage system to cover all frequency from 400MHz to 2500MHz is realizable if the system devices compatible with the characteristic parameters. Find out characteris- tic parameters of POI（ Point of Interface） and filter for intensive inner building wireless coverage system by analyzing vari- ous types of interference, such as spurious emission, receiver blocking and intermodulation. Indoor signal leakage and sig- nal switching are analyzed as well as interference analysis at the same time.
