PowerBeam M5 is an integrated solution for building wireless bridges operating in 5 GHz band, a unique construction, offers unparalleled performance in such a compact device.  PowerBeam M5 can also operate in Router or Bridge mode. The PowerBeam can be easily mounted in a variety of ways thanks to the innovative mechanical design.
The PowerBeam directs RF energy in a tighter beamwidth. With the focus in one direction, the PowerBeam blocks or spatially filters out noise, so noise immunity is improved. This feature is especially important in an area crowded with other RF signals of the same or similar frequency.
