xMax

xMax developed by xG Technology is a wireless communications technology whose developers claim is low power and provides a high data rate over a distance of about 13 miles.
A fundamental paradigm shift in the way radio signals are modulated and demodulated.
Developed by xG Technology in Florida Rather than transmitting many RF cycles for each bit of data to be sent, xMax does it in a single RF cycle.
Power is saved not only in the transmission, but because receivers will only recognize single-cycle waveforms, power isn't wasted on un-intended RF signals .
