Wi-SUN RF Transceiver Module



Using the open, global standard IEEE.802.15.4g, Wi-SUN transmission distance could be up to 1 km in an open area. Compared with other LPWA technologies, it not only requires no communication cost, but also can automatically switch the connection target according to the actual radio wave situation through a multi-hop network, achieving higher reliability.
In the development of smart cities and smart grids, it has become a communication technology for the construction of large-scale mesh networks required by them.
