Multi-frequency Roaming and Layered Networking For MimoMesh Wireless Broadband MESH
MimoMesh wireless broadband MESH provides multi-channel roaming mode. The radio can work in multiple channels of single or dual frequency bands. Through roaming switching, the parallel communication of multiple networks is achieved and hierarchical networking is realized.
As shown in the figure below, in the subway network, a track is divided into several regions, and the adjacent regions are separated by two frequency channels. At the intersection of multiple subway lines, multiple frequency channels are used to distinguish them.
Take train 1 running on the track as an example, set 1360MHz for zone 1 and 1440MHz for zone 2 respectively. In area 1, 2 and 3, the working mode of the fixed platform fixed on the track is set as single frequency point mode, and the mode parameters are set as fixed station mode. The working mode of all equipment on the train is set to roaming mode, and the mode parameters are set to mobile station mode.
In this way, when the train is running at high speed, it can realize roaming switch through different regions, so as to realize trans-regional, large-scale and large-capacity networking.
