Has anyone got any experience with using these products?

I have had the Anti theft package with G.P.S included with the buikld on a new Crusader Caravan.
I looked at the wireless towing interface, but decided to go with the reliable redarc system for braking.

They do not include enough information on the towing system.
For example, can someone with a car unit pair with any caravan system?

I would be surprised if wireless braking is permitted under the ADRs (these govern the design of motor vehicles in Australia) and if it is it shouldn't be.
A wireless link may, and often does, fail for many reasons not the least of which is a high power transmitter nearby eg. police car, Amateur radio, powerful CB, commercial TV or radio transmitter, private frequency user, VKS737 user etc. I would not entertain such a link protocol for a safety system without a host of carefully considered fail safe mechanisms. Just stick with a plug and cables, they may not be perfect but they are a damn site safer than wireless in this situation.

Agree Mike , don't think I would like to be relying on a WiFi or Bluetooth connection to get me down Bulli pass or Cunningham's gap .

If it is not permitted then there are quite a few unauthorised systems installed around the countryside.

If that is the case they are very unwise or ill informed people.

Re interference; RADAR systems use the one antenna for transmission and reception. The transmitted signal strength can be in the kilowatts and the received signal strength can be mere milliwatts.
Just saying that interference from nearby radiation sources need not be a problem in properly designed systems. If there was any interference then it would come from over modulated AM transmitters which splatter over the whole frequency spectrum.
We know nothing about their antenna design. They could incorporate directional antennas.
There is a FCC certification noted and that incorporates testing for Electro magnetic interference.
Hi
I just come across these products.
