Cordless Phones and wifi...

[D_Mike]

I have a (basic) wireless network (802.11g) I am trying to set up (have set it up, but its not working) at home. I also have a rubbishy BT cordless phone set (not digital). I think the phone is killing the wireless network as they are both in the same frequency spectrum (2.4Ghz). I have tried changing the channels of the network but this no effect. So basically, I am looking for a DECT phone that is 5.8Ghz not 2.4Ghz. I know these exist but I can't find out which ones are which... does anybody know of a 5.4Ghz DECT phone system?

My Dect system works fine with a wireless network. They're just boggo BT 3010s and a variety of wlan kit.

My el'Cheapo DECT phones don't mess with my Wi-Fi.

DECT phones operate in the 1.88 to 1.9 GHz band so it is unlikely to be that causing your interference. Details here www.dectweb.com/dectforum/publicdocs/TechnicalDocument.PDF

On the otherhand Bluetooth does operates in the 2.4GHz band so if you have any Bluetooth devices (mobile phone headset for example) operating nearby they may interfere but it is still highly unlikely due to the frequency hopping that bluetooth employs.

I have a digi-sender type device that transmits my satellite TV channels around the house and this DID interfere with my wi-fi network. I had 4 channel choices on the digi-sender, and changing to another channel solved my problem.

I thought it was my DECT phone or Bluetooth on my T610 interfering at first, but the digi-sender was definitely the source of my problem.

just get any modern DECt phone and you will be fine.

Changing WiFI channels wont help - you have 11 channels between 2.4 and 2.483Ghz that are 22Mhz wide - so they all overlap to some degree other than 1, 6 and 11. A 2.4Ghz phone blasts RF out over the whole band

Me too, I have an 802.11g network at home which works fine with the 2.4GHx cordless phone. But I had terrible problems getting the wireless adapters to connect until I updated the firmware on the wireless router.

Analogue cordless phones aren't anywhere near WiFi - IIRC they operate in the HF spectrum somewhere.

I expect it's a common-or-garden EMC (electromagnetic compatibility) problem - much consumer radio kit is utterly crap at rejecting out-of-band signals. After all, why spend 20p on a filter when it can go in the profit margin instead?
