Re: Solution for Cordless phone QRM



Most home wireless networks use 802.11g or the older 802.11b.  Both of
these are in the 2.4Ghz band, so moving to a 5.8Ghz cordless phone does
solve the interference problem.  A few people have purchased equipment
using 802.11a.  This is on 5.8Ghz but did not become as popular as
802.11b/g.  So for most people, replacing their 2.4 cordless phones
with 5.8 will do the trick.  Of course, microwaves are on 2.4 Ghz also.
 I solved the microwave problem by getting directional antennas so the
802.11g signals were just too strong to be bothered by the microwave.

But it is good to know about the DECT 6.0 1920-1930 Mhz phones.  Thanks
for the information.

 If you want to avoid interference to the 902MHz,
 2.4GHz, and 5.8GHz ham bands when using a cordless
 phone, then look for a DECT 6.0 model.
 This was authorized earlier this year by the FCC in
 the Unlicensed PCS band from 1920-1930 MHz.

 Even Wal*Wart has them.  I saw two different models at
 the local store.
 
 They were specifically made to address the complaints
 by consumers that the 2.4GHz and 5.8Ghz cordless
 phones trash their home wireless networks.
