Cordless telephone

A cordless telephone or portable telephone is a telephone with a wireless handset which communicates with a base station connected to a fixed telephone landline (POTS) via radio waves and can only be operated close to (typically less than 100 metres of) its base station, such as in and around the house. Unlike a standard telephone, a cordless telephone needs household mains electricity to power the base station. The cordless handset is powered by a battery which is recharged by the base station when the handset is connected to the base station when not in use.

In the United States, there are four frequency bands which have been allocated by the Federal Communications Commission for use by cordless telephones. These are:

  • 43-50 MHz
  • 900 MHz
  • 2.4 GHz
  • 5.8 GHz
