The design, installation and commissioning of the Luoshan MMDS8+1 system was finished by technicians of the Luoshan Radio and TV Signal Relay Station autonomously. The system has feature of simple- operating and stable function since putting into operation. The fail-over time was shorten to 2 seconds from 5minutes. This article is to introduce the operating principle of the MMDS system.
