Wireless through walls gets go-ahead

The Federal Communications Commission (FCC) has given its approval to the development and use of ultra-wideband wireless technology, devices designed to transmit signals through walls, alleviating the need for cables to connect phones and computers.

The Federal Communications Commission (FCC) has given its approval to the development and use of ultra-wideband wireless technology, devices designed to transmit signals through walls, alleviating the need for cables to connect phones and computers.

Based on low-power radar, ultra-wideband allows wireless devices to transmit signals through thick walls and across long distances and is designed to allow microprocessor "chips" installed in computers, televisions, and appliances "talk" to one another without the need for wires and cable hook-ups.

However, ultra-wideband signals will use the same range of frequencies currently used by cellular phone companies, so its low-power requirements are critical so its signals don't interfere or override those of wireless phone users.
