In the case of sudden large-scale power outage, the communication base station may not operate normally, resulting in the interruption of people's communication。In such a case, the test is not only the disposal capacity of the relevant departments and units, but also the mentality of the broad masses of people to deal with a large area of power outage。

It is important to have an emergency communication plan:

Large-scale power outage has a great impact on people's production and life。As the scale of power grid continues to increase，In the event of a major power outage，It may cause "lifeline" projects such as transportation, medical care, communications, and water supply to fall into disorder or stop operation，Production operation scheduling, hazardous industry security and other links will face severe challenges，It may cause huge losses and adverse effects on the country and people's property。According to the actual needs and application scenarios of emergency communication, Beifeng Communication combined with new communication technologies, to create a MESH wireless AD hoc network system, the overall design idea to meet the particularity of urban large-scale power outage emergency communication。

Beifeng MESH wireless ad-hoc network system is a mobile broadband multimedia communication system designed with a new concept of "wireless mesh network"。The system adopts the distributed network architecture without center AD hoc network, the same frequency network, multi-hop relay, all nodes can realize the real-time interaction of multi-channel voice, data, image and other multimedia information under the condition of non-line-of-sight and random fast movement。The system has powerful functions and excellent performance, and supports any network topology, such as point-to-point, point-to-multipoint, chain relay, mesh network and hybrid dynamic topology。The whole system is convenient to deploy, flexible to use, simple to operate, and easy to maintain。
