What's the best Mhz for a home cordless phone?

Question

I'm looking to buy today a home cordless phone. I want the best range, sound etc for around 50 to 60 dollars or so. What Mhz should I look for

Answer 1

46/49Mhz, but they don't make them anymore.

The higher the frequency the shorter the distance at the same power consumption.

I would look for a 900MHz digital phone if you could still find them.

2.4GHz have a problem with interference, Wireless networking, Bluetooth and microwave ovens run at 2.4 Ghz.

5.8Ghz phones don't have an interference problem but are at a higher frequency, therefore they will consume more power to have the same range as a 900Mhz phone.

Answer 2

The 5.8 Ghz. phones are the same power level as the 2.4.. They are all limited. RANGE is a problem as frequency increases. All the hype about 'spread spectrum' 5.8 phones is just that. Higher frequency - less range.. I have proven this with comparisons with 900 Mhz. and 2.4 Ghz. phones. It should make it around the house, but on a line of sight test, the 900 took first place, 2.4 second, and 5.8 last!! I have also NEVER had an interference problem on 2.4 with any WiFi or microwave oven!! I used to be able to hear the old 46 Mhz. phones, (analog) blocks away..!! BY THE WAY, read the fine print. Most of the new 5.8 Ghz. phones use 2.4 Ghz. as the base frequency!!!!! (Both used.)

Answer 3

I've gone up the scale, from 900 MHz to 2.4 GHz, and now I'm at 5.8 GHz.

Basic problem w/ 900 MHz and 2.4 GHz: interference. 900 is the unregulated ISM band in the US, so there are an awful lot of users there. 2.4 has all of the 802.11 b/g wifi activity, as well as the occasional microwave oven user.

I haven't had the 5.8 problem of using up power, mostly because many phone mfgrs have figured out how to economize power usage in their transceivers, while taking advantage of rechargeable long life batteries such as lithium ion. One day we'll have the problem of having too many users at 5.8, but that will take time, like every other RF technology.

The drawback with 5.8, though, is that you won't find many single unit phones in the $50-60 range. And if you do find one, it's probably not a true 5.8 anyway, but a hybrid 5.8/2.4. Not that it all matters, but just so you know.
