The feeder link between FES and the satellite is in Ku band, while the link between mobile terminals and satellite is in L band.

Radio could carry sound without wires.

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

Radio waves. There's another thing.

And radio waves are limited.

Harmonics

Spheremonics

These radio waves penetrate through walls.

Mobile radio, general

That blue line there is my brainwave.

Whenever current flows through the coil, this becomes an electromagnet.

They had 53 television and 61 radio transmitters, including 49 ultra short radio wave transmitters.

Heinrich Hertz, when he discovered radio waves in 1887, he called them radio waves because they radiated.

These result in electromagnetic radiation ranging from radio waves to X rays, high energy protons and changes in the interplanetary solar winds.

FUNCINPEC radio and television were shut down and a number of parliamentarians went into exile.

We soon tune in to Ivan's wave length.

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

Now you have to remember, this is 10 years before Heinrich Hertz proved the existence of radio waves 15 years before Nikola Tesla's four tuned circuit nearly 20 years before Marconi's first broadcast.

What's the point of these radio waves that you've found?

Jansky had made a historic discovery, that celestial objects could emit radio waves as well as light waves.

Phase Harmonic Advanced Synthesis EXperiment

And then we have the radio waves, they have the issues I've just mentioned.

Only visible light and radio waves from the cosmos can be detected at sea level.

They are commercially used in secondary batteries and coatings for shielding against radio frequency and electromagnetic interference.

The main innovations relate to the use of active antennae, miniaturization of radioelectric functions and the introduction of new frequency bands

Downlink emissions could be particularly damaging and already the emissions of some satellite systems had severely curtailed radio astronomy observations.

(c) A radio science payload this includes X and K band transponders and an accelerometer

Hyperspectral imaging these systems acquire data over a range of wavelengths in the visible, short and long wave infrared (thermal) regions of the electromagnetic spectrum.

You probably think the electrons in an electric wire move instantaneously down a wire, don't you, at the speed of light when you turn the light on. They don't.

Hafun's only communication to the outside world is through short wave radio.

The atmosphere itself radiates at particular wavelengths (especially in the infrared).

Electrons bumble down the wire, about the speed of spreading honey, they say.

By August 1997 there were about 85,000 customers of public mobile telephone radio communication networks.

We use them to communicate, cook, and diagnose and cure disease. The unified theory of electromagnetism has led to profound advances across all physical science, from atomic physics (where lasers and masers are essential tools) to cosmology (where the microwave background radiation is our window on the Big Bang).

(b) Radars with electronically controlled beam direction using phased array antennas.

Mobile radio (VHF UHF FM transceiver, general)

The communications package includes an S band downlink and amateur radio store and forward communications with an audio repeater to stimulate radio interest among schoolchildren.

Seven powerful, 13 low powered and two medium wave State radio and television stations operated in Lithuania.

Remember, 2001, we had less than two hours radio contact with the outside world.

The victim's brother, Louis Galicia, told ABC station KGO in San Francisco that Frank, previously a line cook in Boston, had landed his dream job as line chef at San Francisco's Sons Daughters restaurant six months ago.
