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.
