Expand AllCollapse All

  1. No. A spread-spectrum radio, like all FCC Part 15 devices, is not allowed to cause harmful interferences to licensed radio communications and must accept any interference that it receives. 

  2. Spread-spectrum radios work by frequency hopping and transmitting at discrete frequencies over part of the unlicensed band, rather than by transmitting over a very wide part of the spectrum as some other devices do.

  3. Yes. Two spread-spectrum radios can be used to connect two computers.

  4. No. Removing the interference will remove the radio signal. The radio, like all FCC Part 15 devices, is not allowed to cause harmful interferences to licensed radio communications and must accept any interference that it receives.
