Overview
Wireless interface products provide a cost effective alternative to expensive hard wired connections. The wireless product provides continuous， 24/7 communication using the FCC licenses free 900MHz frequency. Using Frequency Hopping Spread Spectrum (FHSS) technology， a robust signal is provided that is virtually free from disruption due to interference. This technology has been proven in thousands of installations worldwide.
