Question

Which cordless phones are the best in terms of battery life and reception? The 2.4GHz, 5.8GHz or the 900MHz?

Answer 1

I would not use 2.4GHz. ever. 5.8ghz would probably give you better range than 900mhz.

Answer 2

Reception ? 5.8 mhz, battery life depends on the phone itself and the user. Look for a phone with DECT technology. It looks for all other devices in your house and avoiods sharing the signal with them by moving a little bit to a different band so that  no one is interfered with.

Answer 3

The 5.8 Ghz. phones have the same or LESS range than a 900 Mhz. or a 2.4 Ghz. phone. They all run very low power,  about 1 tenth of a watt, and digital spread spectrum HYPE is just that. Frequency hopping has nothing to do with range. Read the fine print. Even the 5.8 digital phones use 2.4 or 900 (like most AT&T) in the base. The higher the frequency, the LESS RANGE. Ask any electronic expert. The DECT 'technology' is a joke also. Many phones on the market employ multiple remote handsets, caller ID, etc. There is no special advantage to 1900 Mhz. or a DECT type phone. Again, mostly marketing hype!! I have never experienced any interference problems on any 900 or 2.4 Ghz. phone, and that includes around microwave ovens, WiFi networks, etc. A good system will seek a clear channel, eliminating any problems. I have tested all the phone ranges, 2.4, 5.8, and 900 analog. Range was about the same on all, with a slight edge by the 900 Mhz.!! (Remember, lower frequency, better range.) Remember the old 49 Mhz. cordless analog phones of the 80's.?? They would go blocks, and the base be heard a quarter mile away with a good antenna! Lots of scanner listening with those however, so the companies switched to 900 analog next. As for battery life, it is more with color displays and lights on the handset, along with use that lessens the battery life. They all have about the same power drain. (Without the color displays and lights.) Look for a Lithium Ion or Nickel Metal Hydride battery, they do not develop a 'memory' problem, like the old 'NiCad' batteries. The less bells and whistles, the longer the battery life. Of course, it also depends on how much you talk.

Answer 4

900 Mhz has the LEAST range, and least security, (security is enhanced only with DSS) The reason they get the least range is because they transmit much less power output then "newer" cordless phones..

DSS and FHSS is technology used to reduce interfearance, and improve on security, it is not marketing hype and has no effect on range, and is not marketed to improve range.

DECT phones operate at 1.9ghz, and provide the best range, and battery life as the lower the frequency, the further the range. They are also secure, and call quality is very clear.

2.4 Ghz provdes the next best range/battery life , as most radio scanners to not cover this range security is good, but increased with the addition of FHSS. The fault in this radio spectrum is that it shares the frequency with wifi, and the two may interfere with each other.

5.8 Ghz phones were made to improve on the 2.4Ghz phones short comings, however it was at the cost of range, and battery life. Of all cordless phones (aside from 900 mhz) if will provide the least range, and battery life.
