What's the difference between 900 MHz, 2.4 GHz and 5.8 GHz phones?
Your average cordless phone is actually a radio transmitter/receiver that operates across various radio frequencies. The three currently used frequencies are 900 MHz, 2.4 GHz and 5.8 GHz. As you step up in frequency, you'll experience an increase in the signal clarity and the range your phone can reach from its base station. However, the actual range and sound quality of your phone can be affected by obstructions within your home and interference from other electronic devices. Here are some general guidelines for choosing one of the three frequencies:
900 MHz
Most manufacturers have begun to phase out 900 MHz phones with AT&T having phased them out completely. Phones operating on this frequency are fine for household use and reasonably priced, though the features offered with these phones are limited.
2.4 GHz
The majority of phones on the market today operate on the 2.4 GHz frequency. This higher frequency provides better performance and sound quality than 900 MHz models. With more models to choose from, you'll also find more available features, including integrated speakerphones and support for multiple handsets. One thing to keep in mind is that other electronic gadgets, from baby monitors to wireless networking gear, increasingly use the 2.4 GHz band and may cause interference. If you use these items in your home, consider purchasing a 5.8 GHz phone.
5.8 GHz
5.8 GHz phones offer the latest in cordless telephone technology with the best clarity, range and possibly security. The biggest advantage to a 5.8 GHz phone is that its frequency band is less trafficked than the 2.4 GHz band, resulting in less interference. The chips that generate the 5.8 GHz signal are more expensive to manufacture, so expect to pay a bit more.
Analog versus digital
You can find both analog and digital models within all three of the main frequencies (900 MHz, 2.4 GHz and 5.8 GHz).
Analog
Analog technology applies to a system of recording or transmitting sound. In an analog system, the changing energy in the sound is converted to energy variations in another medium, for example, magnetism in a tape.
Analog cordless phones are the most affordable and available option. You will experience adequate range and good voice quality. Drawbacks include poor security (anyone with a radio scanner will be able to listen in) and static when you move too far away from the base station.
Digital
Digital technology is also system of recording or transmitting sound. In digital systems, the changing energy in the sound is continually measured.

Long range cordless home phone?
firemandan
I used to have a 900mhz phone that had a range of several hundred feet. Now that it has dies though I have not been able to find another system that works any where near as well as my old one. I have tried two systems that work on 5.8ghz from Uniden and Pansonic but both have horrible range. I am considering tiring the new DECT 1.9ghz phones but i am not sure that will work any better for me. Whatever I get needs to be able to be purchased and possibly returned locally in the Charolote North Carolina area.
In particular any recommendations for specific phones?
Answer
In general, you can expect better clarity as you move from 46-49 MHz models (which are overcrowded with baby monitors and walkie-talkies) to 900 MHz models (which most homes use for cordless phones) to 2.4 GHz models. The primary benefit of 5.8 GHz models is the avoidance of interference with 802.11b wLANs and microwaves. If interference is your primary concern, make sure you purchase a fully 5.8 GHz phone.2 Otherwise, a dual transmission phone will give you better battery life.
As for range, here are some average maximum distances for the different technologies. Keep in mind that these numbers are very subjective and depend on factors such as obstructions, frequency interference, transmission technology, and even weather. The higher figure listed assumes ideal conditions are present.
46-49 MHz - 40 to 250 feet
900 MHz - 75 to 400 feet
900 MHz w/spread spectrum - 200 to 1500 feet
2.4 GHz w/spread spectrum - 300 to 2000 feet
5.8 GHz w/spread spectrum - 300 to 2000 feet
In addition to their other advantages, the 2.4 GHz and 5.8 GHz frequency bands are above the range that most scanners can intercept, making it much more difficult for eavesdroppers to listen to your conversations.
