The WNM Wireless Network Module from Moore Industries provides a wireless communications link between field sites that are in rugged or impassable terrain, with a single unit transmitting for up to 30 miles and the ability to act as a repeater for a virtually unlimited transmission range. The bi-directional WNM employs 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 close proximity. The module operates at standard operating frequencies of 902-928 MHz or 2.4-2.4835 GHz. When it is set in the Smart Switch Ethernet (SSE) mode, the WNM enhances the speed and reliability of data packet transmission by determining the most efficient path of broadcast on a packet-by-packet basis, the company says.
