which cordless phone has the longest range?

i want to know where to get it?

Longest range - Due to higher transmitter power (1 watt) allowed by the FCC, you can expect seven to eight times the range of an earlier .001-watt cordless 43-49 MHz telephone, and about three or four times the range of an analog or digital 900-MHz cordless telephone. The 900-MHz phones all have a better range due to the wavelengths being shorter -- shorter waves are easier to bounce off objects. However, only the DSS versions of the 900-MHz cordless telephones can use the full 1 watt of transmitting power. The normal digital and analog versions of the 900-MHz phones have a lower power limitation.

Best sound quality - Since the spread spectrum signal is uniformly spread over a wide range of frequencies for transmission, the signal avoids interference and noise from other signals. Older 43-49 MHz cordless phones had only 25 crowded channels and were very susceptible to interference. And 900-MHz analog phones still suffer from the interference problems of any analog cordless telephone, and can be heard on inexpensive radio scanners or your neighbor's same-brand cordless telephone. A spread spectrum phone is much less susceptible to signal fading. This makes the reception of a spread spectrum cordless phone much less sensitive to the location and orientation of the handset than that of a conventional lower-power analog cordless telephone.

Highest security - Due to digital transmissions and constantly changing frequency channels in use, only the matching receiver has a copy of the pre-assigned spreading code. Millions of scrambling codes are available and are selected automatically when the headset is lifted from the cradle. Common radio scanners I absolutely love my Panasonic 5.8GHz phone.
