The WNM wireless network module has been redesigned with a sleeker housing and now incorporates both serial and Ethernet communications in one model. The module provides a wireless communications link between field sites that are in rugged or impassable terrain, with a single unit transmitting for up to 30 mi and with the ability to act as a repeater for almost unlimited transmission range. The bi-directional WNM uses Spread Spectrum Frequency Hopping technology to avoid interference problems caused by crowded radio spectrums. This technology allows multiple radio networks to use the same band while in proximity.
