Yes i confirm Wireless unreliability since 2001



I post on a regular basis since 2001 that wireless alarm systems are
unreliable during Radio Frequency Interferences (RFI).

Since that time, several professional specialists (they call
themselves like that but I don't see why in view of theyre knowledge)
have mentioned that the new systems avoid RFI but they are unable to
explain how.
Other pro's (?) say that RFI is detected but they can't explain how.
It doesn't exist that marvelous/imaginative wireless alarm system.

Instead of analyzing the problem and submitting it to they're "product
manufacturers" for eventual support, no, pro's wanted to "handle" it
themselves, they're uses a more in theyre reach technique, they
attempt to block my post, email en Internet access, they insult and
more...
 Pro's don't like what I say...
 Pro's are unable to counter-argue with technical supported arguments.

Instead of looking to the real problem RFI causes, pro's try to hide
reality, they raise unjustified smoke curtains in an attempt to
generate uncertainty, fear in order to put my statements in doubt.

Business and financial interests obliges...

All attempts failed and convince me even more that I have to inform
the new readers...

The problem of RFI on wireless alarm systems is to serious to be
neglected and not mentioned to the purchasers.

All REAL PROFESSIONALS in the wireless data communication business
know that RFI problem, "low level electricians" in the alarm
installer/seller business don't.

WHY do Manufacturers not counter-argue by publishing the most basic
data subject theyre wireless data communication loop quality (RFI
avoidance means???, RFI detection means???, receiver quality data???).

WHY? Theyre system have elementary receivers with a large band pass
(SAW filter type band pass), low outside band pass rejection, low
intermodulation quality, etc.. cost obliges.. theyre wireless alarm
systems are RFI sensitive, NO RFI selective warning, they know it but
don't like to publish it.

I will continue posting in order to inform the new readers because I
cant admit so called pro's (?) stupidity that don't admit that there
is a inherent Radio data communication problem with wireless alarm
systems..
Wireless signals can be detected and disrupted from the outside.

So called pro's in that alarm business obviously don't possess the
meager intellectual capacity required to understand the basic concepts
of wireless data exchange principles. Don't overestimate theyre talent
to judge others either.
