Do France beat the US...

I have been informed that at least 2 French manufacturers (DIATEM &
DIAGRAL) have designed theyre wireless alarm system receivers and
transmitters to operate on "dual frequency" on "dual bands".
Even if it don't solve (can't) the RFI muzzling problem, at least it
"may" minimize them.

This require that two individual receivers are used (?).
I still like to see theyre specifications, its maybe just sales talk
without ground like usual in the US.

In the mean time, wireless are still unreliable during Radio Frequency
Interferences (RFI) and nothing cant prevent those external
transmitted signals to be there.
The worst is that when your system is dead, it don't warn you...

Wireless Alarm Systems = Illusionary safety.

You're an idiot.
We've been using spread spectrum frequency hopping for at least 15 years.
France doesn't even make decent fries you think they know how to make radios?
