We are involved in several projects investigating wireless conflict
signals within corporations and hospitals and are finding some strange
results which could impact Wi-Fi and Wi - Max usage and indeed the
whole paradigm first mile wireless use.<br>
<br>
Basically this is what we are seeing<br>
<br>
Open wireless frequencies that have been typical used are 900 - 2.6 and
now 5.8ghtz.<br>
<br>
802.11 of various types operates in both the 2.6 and 5.8 sectors ( 5.8
is 802.11n and 802.16 wi max ) the 900 htz range is packed and so is
the 2.8 ghtz<br>
<br>
Inside of a hospital for instance multiple monitoring equipment types
and portable phone systems operate on the same frequencies and so does
a huge amount of SCADA operations.<br>
<br>
Although channel switching is supposed to prevent signal conflict
wi-fi signal boosters and all wimax whether static or mobile is
continually channel hunting and knocking everything else of of the
channel making many types of systems non usable<br>
<br>
It would seem that a major problem is manufacturers testing their
equipment in a silo arena and this would also be relevant to the white
space transmission requests before the FCC at present<br>
<br>
This looks like a huge problem and if anyone is experiencing the same
issues please contact us<br>
<br>
Apparently Motorola with their Canopy system and Intel ( wi-fi and max
) did a large amount of research but when the conflict issues arose
chose to ignore the results or assumed that channel frequency switch
would fix the problem but its not<br>
