The WNM wireless network module has been redesigned and incorporates both serial and Ethernet communications in one model. It provides a wireless communications link between field sites that are in rugged or impassable terrain, with a single unit transmitting as far as 30 miles. It can act as a repeater for an almost unlimited transmission range. The bidirectional unit 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. Standard operating frequencies are 902-928 MHz or 2.4-2.4835 GHz.
