In 1896, Marconi successfully covered a distance of about 3 km using electromagnetic waves. A little later, he established radio contact across water between Lavernock Point, South Wales and Flat Holm ...

For the first time, researchers have used a laser as a radio transmitter and receiver, paving the way for towards ultra-high-speed Wi-Fi and new types of hybrid electronic-photonic devices.

Researchers have developed a tiny unit that is both an optical transmitter and a receiver.

Why does a spark produce radio waves? Air normally does not conduct electricity. However, if the voltage is high enough (for a given amount of air) the electrical energy causes the air atoms and ...

In 1901, Marconi sent a signal across the Atlantic using the recently discovered radio waves. It paved the way for today's complex wireless communications systems such as satellites and mobile phones.

There’s a big reason those enormous AM radio transmitter towers are surrounded in fences: touching them can be incredibly dangerous on account of the enormous amounts of power pushed through ...

The transmitter was actually a pretty simple circuit, just a crystal-controlled oscillator and an RF amplifier really, but still managed about 1.5 Watts output on the 80-meter ham band.

Simplifying the wireless power system, these transmit power optimisation and foreign object detection features in the LTC4125 do not require any direct communication between the transmitter and ...
