I'm getting disgusted with my current ISP and am looking into getting Clearwire, a 2.4GHz based provider up here in Northern Wisconsin/Minnesota.  They sell (as accessories) these little things called "ClearPlugs" that plug into the modem and then into the wall socket, allowing the internet signal to be broadcasted through the home wiring to another ClearPlug in a more adventageous spot for your computer (for a better explanation, see <<http://www.clearwire.com/support/accessories.php>>).  With all the talk about BPL, I am concerned that this could also cause interference with my HF rig.  Does anyone know about this Clearwire accessory and if it could cause a problem for me should I purchase it?  I would just like to be sure I know what I'm getting into.  Thanks!

I don't know that product by name, however, from its name and operation I can surmise that it is a "homeplug" type device. This means that it may or may not cause and receive interference depending upon the standard level or modified standard to which it operates.

All the A.C. plug type networking devices are capable of interfering with and being interfered with by Ham Radio. The degree of interference in either direction depends upon the standards to which they were design and the care used in manufacture. You would have check the BPL listings to see if Home Plug 2 (the standard I am guessing that they will use) is clean. You may also be able to find some direct references to clear plug.

Make sure you can give them the clear_plug back if it interferes.

The 2.4 ghz links may have problems with other home wireless devices like home wireless telephones, too.

Goodluck,

David
