More and more households and businesses today are using cordless phones, made by a variety of companies, including Panasonic, Siemens, and Sony. The cordless phones supposedly sound clearer and have much better range than wired phones. Of course they also provide mobility.

Cordless phones operate on 3 different frequencies, 900MHz, 2.4GHz, and 5GHz. Do those last two frequencies sound familiar? Yep, at least the 2.4GHz and 5GHz frequencies fall in the same frequency bands as 802.11b and 802.11a wireless LANs, respectively -- and the use of the phones can cause significant RF interference to your WLAN.

I know my microwave interfers with my 2.4Ghz phones by making crackling sounds in the phone. Wha does it do to your wireless system?

Wi-Fi (802.11 B & G) are using the same frequency.
