WNM wireless network module for sending process signals between remote field sites from up to 30 miles can act as a repeater for a virtually unlimited transmission range. Bi-directional device employs spread-spectrum, frequency-hopping operating at standard 902–928 MHz or 2.4–2.4835 GHz. In Smart Switch Ethernet (SSE) mode, it determines the most efficient path of broadcast on a packet-by-packet basis.
