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. Older 43-49 MHz cordless phones had only 25 crowded channels and were very susceptible to interference. 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.The normal digital and analog versions of the 900-MHz phones have a lower power limitation. However, only the DSS versions of the 900-MHz cordless telephones can use the full 1 watt of transmitting power. The 900-MHz phones all have a better range due to the wavelengths being shorter - shorter waves are easier to bounce off objects. 001-watt cordless 43-49 MHz telephone, and about three or four times the range of an analog or digital 900-MHz cordless telephone.
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.
