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.
