A wireless intercom is a telecommunications device that enables voice communication without the need to run copper wires between intercom stations. A wired intercom system may incorporate wireless elements.
There are many types of wireless intercom systems on the market. Most wireless intercom systems communicate by radio waves using one of the frequencies allotted by various government agencies. Some wireless intercom systems communicate using the 802.11 standard. There are also systems that advertise themselves as wireless, but communicate over existing building AC electrical wiring
Wired vs. Wireless
One reason to use a wireless intercom system is that the cost of retrofitting a building for a wired intercom system is high. Another reason is the increased portability of a wireless system. With battery-powered radio frequency wireless intercom units, a person can carry a station as they walk around.
