If you are unsure if spread-spectrum communications is right for you, you can try before you buy. Campbell Scientific offers a 900 MHz spread-spectrum demonstration kit that allows you to easily test communications from one point to another using the RF407 and RF451 radios. Testing with RF451 radios will be valid for an RF452 network.

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