Practical Detection of Microwave Line of Sight Fading in Mobile Networks

Modern wireless mobile networks rely on microwave technology for backhual the radio sites with all new technologies to their core network. Microwave is the best solution in urban and sub-urban areas due to low cost and newly provided capacity by microwave links which reaches 10 Gbps. Thus microwave links is a very important aspect in mobile network. Microwave Radio Link design begins by doing the link budget analysis which include specific parameters for the link to operate. Microwave link should be maintained with these parameters to keep acceptable radio performance, capacity and latency. In this work we presented a practical and automated criteria to maintain these parameters as designed without impact on radio performance especially RSL (Receive Signal level). Trial conducted in a live network showing a great enhancement in early discovery of microwave link problems and proactively solving them.
