30% FREE COVERAGE WITH 6.25KHZ NEXEDGE NXDNEXTENDED COVERAGE
As RF signal strength weakens with distance, analog reception becomes increasingly noisy and intermittent. The low BER of NXDN™ improves reception in fringe areas, thereby effectively increasing range by as much as 20% over FM analog, resulting in a 50% increase in coverage area for digital 6.25 kHz.
Furthermore, even compared to digital 12.5 kHz bandwidth operation, the narrower 6.25 kHz bandwidth enabled by the FDMA technology of NXDN™ extends range by 15%. Receiver filters are narrower and can thus reduce noise. The net result is superior clarity over a 30% wider coverage area.http://bit.ly/NXDNScalability
