ARLINGTON, Va. – U.S. military researchers needed a company to develop new ways to model the ionosphere in real time to help predict the propagation of high-frequency (HF) radio waves for improved ...

The LoRa radio communication system is useful for low-bandwidth communication, and as many readers will be aware its special skill lies in delivering long range. For most of us that range tops out at ...

Altair recently announced their acquisition of AWE Communications GMBH (AWE), creators of the WinProp Software Suite. WinProp is known for its wave propagation and radio network planning functions.

It is fitting to begin a book about wireless communication with a look at the phenomena that lets us transfer information from one point to another without any physical medium the propagation of radio ...

It is fitting in a book about wireless communication to look at the phenomena that lets us transfer information from one point to another without any physical medium—the propagation of radio waves. If ...

In the wee hours of Jan. 14, I experienced a radio propagation event I can only describe as magical. If you’re familiar with E-Skip propagation on the FM radio band, you likely associate it with ...

Before the first communications satellites were launched in the 1960s, high-frequency (HF) radio was the principal means to communicate beyond the horizon. Satellite links proved to be more reliable ...

It has to be hard to be a kid interested in radio these days. When I was a kid, there was a lot of interesting things on shortwave. There wasn’t any cable TV (at least, not where I lived) so it was ...

Nick’s Signal Spot is a new feature in which Nick Langan explores RF signals, propagation, new equipment and related endeavors. Maybe you’ve been on the other end of a listener phone call during the ...

A signal traveling between an earth station and a satellite must pass through the earth s atmosphere, including the ionosphere, as shown in Fig. 4.1, and this can introduce certain impairments, which ...
