And those two coils of wire are really, really close to each other, and actually do transfer power magnetically and wirelessly, only over a very short distance.

Eric Giler demos wireless electricity

The way we transmit wireless data is by using electromagnetic waves in particular, radio waves.

What happened back a few years ago was a group of theoretical physicists at MIT actually came up with this concept of transferring power over distance.

Send and receive radio facsimiles

The line carried the telephone signals that would later make Bell a household name.

Harald Haas Wireless data from every light bulb

The thought that you wouldn't want to transfer electric power wirelessly, no one ever thought of that.

There are hundreds of lights in an aircraft cabin, and each of these lights could be a potential transmitter of wireless data.

Amateur Radio Data Transfer with ARQ

The ELINT satellites are designed to detect transmissions of such communications signals as the broadcast over radios and telephones as well as radar and telemetry of missiles emitted during their tests.

I. Direct radio broadcasting capacity

Some countries are relying more heavily on the fixed telecommunication infrastructure, while others are introducing mobile and other radio based networks.

And mind you, most of the energy is not used to transmit the radio waves, it is used to cool the base stations.

And this would then combine two basic functionalities illumination and wireless data transmission.

Could not initiate message transport. Possibly invalid transport.

95. Another means of promoting indigenous issues is through radio.

News and magazine programmes are also distributed via telephone lines and radio circuits for shortwave rebroadcast by regional broadcasters.

Development of United Nations international radio broadcasting capacity

The electricity distribution grid in Arabsalim was also damaged.

Base radio station, transceiver receiver

In China, VSAT systems are being used in voice and data transmission, e mail, faxes, video conferencing and dedicated lines of communication.

Message from our planes

Is it a radio?

And this light can be used to transmit wireless data that these things use to communicate with each other.

12. The media discussed in the report included the print media, film, television, radio, the telephone and the Internet.

There was a possibility for cross connection between the two service areas to uplink from one and downlink to the other.

Public campaigns, radio broadcasts and TV spots, leaflets and posters are also used to disseminate information and raise awareness.

Radio could carry sound without wires.

We think these little wireless sensors are more effective.

The network relies on the use of the Internet, fax, satellite communication, high frequency radio and telex. (Source IDRC)
