Re: Yes i confirm Wireless unreliability since 2001

["Paul" <someones-father-@xxxxxxxxxxx>]

Ive just had a real big issue with a clients Blue Tooth mouse and keyboard
completely stopping an Nx 4 button fob from working unless you are right
next to the receiver.
I thought it was strange because when i installed the buttons and receiver
in the first place, the range was great. It would even arm and disarm half
way down the street.
What I did to proove the problem was to activate the fob from right next to
the Blue tooth equipment,  straight away the fob would fail to activate, as
soon as I turned the Blue Tooth off, it would be back to full strengh again.
A bit of a worry really and the client wants us to fix it.
