Cordless phone headsets are great for homes and offices. You can keep your hands free while taking calls and making conversations. After a while, though, the cable near the connector can fray or break. Instead of purchasing a new one, you can save money by replacing the broken cable and extend the headset's life. more »

A cordless telephone or portable telephone is a telephone with a wireless handset that communicates via radio waves with a base station connected to a fixed telephone line, usually within a limited range of its base station (which has the handset cradle). The base station is on the subscriber premises, and attaches to the telephone network the same way a corded telephone does.
The base station on subscriber premises is what differentiates a cordless telephone from a
mobile telephone. Current cordless telephone standards, such as PHS and DECT, have blurred the once clear-cut line between cordless and mobile telephones by implementing cell handover, various advanced features, such as data-transfer and even, on a limited scale, international roaming. In these models, base stations are maintained by a commercial mobile network operator and users subscribe to the service.
Unlike a corded telephone, a cordless telephone needs mains electricity to power the base station. The cordless handset is powered by a rechargeable battery, which is charged when the handset sits in its cradle.
Frequencies
In the United States, seven frequency bands have been allocated by the Federal Communications Commission for uses that include cordless phones. These are:
* 1.7 MHz (1.64 MHz to 1.78 MHz & up to 5 Channels, AM System)
* 43–50 MHz (Base: 43.72-46.97 MHz, Handset: 48.76-49.99 MHz, allocated in 1986 for 10 channels, and later 25 Channels, FM System)
* 900 MHz (902–928 MHz) (allocated in 1990)
* 1.9 GHz (1880–1900 MHz) (used for DECT communications outside the U.S.)
* 1.9 GHz (1920-1930 MHz) (developed in 1993 and allocated U.S. in October 2005)
* 2.4 GHz (allocated in 1998)
* 5.8 GHz (allocated in 2003 due to crowding on the 2.4 GHz band).
