Phones that don't interfere with wireless networking

[Robin Bowes]

Hi,

I've read mention on these lists/forums of cordless home phones that use
a different frequency range to that used by wireless networking and
therefore don't cause interference.

Can anyone point me at examples of such phones?

Are they available in the UK?

Digital Cordless (DECT) phones available in the UK use a dedicated frequency of 1900MHz therefore don't interfere with 802.11b/g wireless networking that uses 2.4GHz.

The 2.4GHZ band is unlicensed and therefore by definition any device can use this frequency so I suppose you could get a phone using 2.4GHz that has been imported from the US but I can't say I've ever seen them.

Robin,

The DECT standard that's in use throughout Europe (including the UK)
uses frequencies that stay away from the 802.11 standard. It only tends
to be the US 900Mhz phones that have problems with WiFi.

And for the information of any US residents looking for WiFi safe phones, go for the 5.8GHz models. 900MHz is the other alternative but they tend to be analogue only.

Just be sure to check the specs of your 5.8 GHz phone before buying.
Some either transmit or receive on 2.4 GHz which makes them rather
pointless for avoiding 802.11b/g interference.

Yep. Last time I checked, I think the Panasonics "5.8"s tromped all
over everything, but the 5.8 Unidens stayed in their own yard.

Actually the Panasonics are good, they only use 5.8. Decent phones, too.
We have this model:

and a couple of the expansion handsets and there's no interference with
our 802.11g setup.

Ah, thanks. I must have got the wrong and of the stick and assumed that
DECT was 2.4Mhz.

I did wonder why I never had any problems with my previous DECT phones!

Radioshack sells some that are 5.8 only, too.

I had some AT&Ts that were advertised as 5.8, but really used 5.8 for
broadcasting and 2.4 for receiving (or maybe the other way around).

If you have a 2.4Ghz phone, I've found that setting your wireless network to use Channel 10 or 11 eliminates any interference problems between phone and network.

(unfortunately, my microwave oven still knocks out my wireless network...) :-(
