Many users are concerned that wireless communications can be “hacked” into by intruders. The WLM Wireless Link Module from Moore Industries provides accurate, reliable and secure wireless connectivity between remote field sites by employing frequency hopping spread spectrum (FHSS) technology. Here, the transmitter changes the frequency at which it is broadcasting in a random pattern. Only a receiver programmed with the exact same algorithm is able to listen to and follow the message. Of all the wireless technologies on the market, FHSS is the most secure, says Moore.In addition, the WLM has high security features such as dynamic key encryption and 32 bit CRC error correction for secure, robust communications. For increased security, the WLM is user-configurable via a PC-based HyperTerminal interface. It is also available pre-configured from the factoryThe WLM bi-directional wireless module supports either Ethernet or serial (RS-485) communications at speeds up to 188 kbps and ranges up to 25 miles, and operates at FCC license-free frequency ranges of 902-928 MHz or 2.4-2.483 GHz.www.miinet.com
