Whats the difference between 1. 9GHz and 5.8GHz?

Question

Is one better that the other?? I need a nbew phone, I love my panasonic phone system but they discontinued my line and to get a replacement phone is about 199. and thats only and extra hanset, not the base. Ughhh!! I need help choosing a good clear phone.

Answer 1

I have tried every spectrum cordless phone from 900 Mhz. to 5.8 Ghz. At approximately 100 milliwatts of power, I see little difference. I have had NO interference problems with 2.4 Ghz., or any others. However, theoretically, the 1.9 Ghz. would have a slight advantage for range. HOWEVER, that depends on terrain. In some buildings, that may be two rooms down the hall, in some homes, across the whole house.  All the 'Spread Spectrum' c**p means little, except to eliminate listeners. Digital stops most of that anyway. A lot of the newer digital cordless phones sound lousy to me, just buy one you like, for looks or features. There is such a miniscule difference nowadays. It's like 'you want 2 cans with a string', or 'two gold cans with a wire'?? Good luck.

Answer 2

1.9 GHz works at greater range from the cell centre but 5.8 GHz  is better (potentially) for quality as more channels are available. You pays your money and you takes your choice.

If you normally have no problem getting access then 1.9 GHz should cost less.

Answer 3

to answer your question, when it comes to radio waves the LOWER the frequency the better range, and longer the battery life given all other factors are equal.

so a 1.9Ghz DECT phone will be better then a 2.4Ghz and 5.8Ghz phone, and a 2.4Ghz phone will be better then a 5.8Ghz phone.

DECT = digital enhanced cordless telecommunications. the 1.9Ghz range is set aside exclusively for cordless telephones, and there should be no interference from other electronic devices.

2.4Ghz operates on the same frequency as many other wireless devices, such as WiFi, wireless video cameras, and can even get interference from microwave ovens.

5.8Ghz is another unlicensed spectrum  that cordless phones operate on, there are other devices that may cause interference with this range, but there are less consumer devices that operate in this frequency. municipal wifi networks operate in this frequency, although I am unsure of what if any municipalities actually use this frequency for there wifi devices.
