This may be a bluetooth adaptation. I think it uses hopping.<br>

<pre wrap=""><!---->--snipped--<br><br>I think the proposal has three aims:<br><br>*Reissue that part of the Act to make its formatting bureaucratically-compliant<br>in wording and layout (no effective change here)<br><br>*Take the current two segments of the 2.4 GHz ISM band (2400-2483.5 MHz)<br> - 2400 MHz - 2463 MHz (4W EIRP Max)<br> - 2463 MHz - 2483.5 MHz (0.2W EIRP Max)<br> and aggregate them together (remove the 0.2W EIRP limit on the second half)<br> under 4W EIRP Max.<br><br> *The FCC Rule permits the operation of broadband frequency hopping spread spectrum<br> devices in the frequency band 2400-2483.5 MHz.
