Question about upgrading cordless phones in the house

by Big Steve / January 27, 2008 9:29 AM PST

Which forum would I post a question or questions about anything to do with cordless phones in the house? My question has to do with having more than one cordless phone in the house; at the moment I have 2 and each one operates on a different frequency.

I have one 2.4GHz digital cordless phone by Radio Shack and one 5.8GHz digital cordless phone by Panasonic. I need to replace the 2.4GHz digital cordless phone by Radio Shack with something newer because it's getting old.

If I end up with not one but two 5.8GHz digital cordless phones in the house; each phone possibly being a different brand; is there a chance I will have any interference problems between the 2 cordless phones since both phones will be 5.8GHz frequency models?

(NT) Only if they're both in use at the same time

No PC issue here; just had a question about cordless phones with different frequencies and since there is no specific forum on this website labeled "phones or cordless phones", only one in place for "wireless phones" I decided to post my question in this forum which seemed to work because I received 3 replies. Cordless phones may not be considered a big issue on this website but a forum specifically set up to address questions and issues related to them I think would be of some benefit.

If I wanted to set up a cordless phone in a back bedroom where a Dell desktop PC is set up which is connected to a DSL modem, a Lynksys(sp?)wireless router and a host of other things if I did install a 5.8GHz cordless phone in that back bedroom on the desk next to my PC would that cause my PC or the wireless router to have problems? Interference problems? Most wireless routers operate on 2.4GHz I think.

Again, shouldn't be a problem.

If for some reason there is interference both the router and the phone will change channels.

So far, so good.

The newer 5.8GHz units seem to coexist well.

Most support multiple channels...
by John.Wilkinson / January 27, 2008 9:45 AM PST

If two phones of the same frequency are in use at the same time and are from different systems they can potentially interfere with each other. However, most support the switching of channels in case of interference, so if it happens just follow the manual's instructions to switch.

Note that it's also possible for a cordless phone to pick up the call of another individual close by. That's why newer cordless phones also include a security option where one of XX thousand codes are chosen at random to uniquely link the cordless handset to its base, usually changeable by unplugging the phone for a few minutes before reconnecting.

Hope this helps,

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
