EtherNudge operates as a transparent cable replacement for a physical cable over air in a narrow band, mid or long distance communication system for stationary or mobile fading radio channels.

As an enhanced software configurable radio modem, EtherNudge allows for software controlled frequency and waveform setting based on environmental and regulatory needs.

Depending on the frequency, EtherNudge's communication range exceeds 100km with less than 1 Watt of mean transmission power.

EtherNudge is designed to work with line-of-sight and non-line-of-sight modes under the worst channel conditions presented by rough environments where it performs near the theoretical limits.

EtherNudge steps in where conventional solutions reach their limit.
