Keeping Your Microwave Off Your Phone
The phone we have uses the 2.4-GHz frequency, which just happens to be the frequency most likely to have interference problems.
"The interference can go two ways," explains David Heim, Deputy Editor of Consumer Reports magazine. "Sometimes you'll hear static and crackling on the phone and sometimes the phone will make other things misbehave, such as baby monitors, wireless speakers or wireless computer networks."
If you're buying a new cordless phone and you think there could be interference problems (because of other wireless devices you already have) pick a phone with a higher or lower frequency.
"Look for phone in the 5.8-GHz frequency band, it's labeled on the box, it's not hard to find," Heim says, "or go down to 900-MHz. Again, it's a number you'll see on the box, you'll see it in the store, not hard to find. Those two frequencies are much less likely to cause interference."
By the way, phones labeled "802.11-friendly" should get along with your wireless computer network. But that doesn't mean they won't interfere with other wireless devices you have.
