The Family Radio Service, or FRS, is a system allowing short-range communications between friends and/or family. The system uses frequency modulation, or FM, signals, improving on the older citizen's ...

While iPhones can operate on cellular networks, it is better to use their data features on a Wi-Fi network, if one is available. Not only is Wi-Fi data typically faster than cellular data, but it is ...

The higher a marine VHF antenna is mounted, the greater the distance its VHF radio can transmit and receive. That means one of the best installation locations for top radio performance is overhead on ...

Experimental technologies offer elegant, inexpensive solutions. Researchers are studying applications and materials for creating radio antennas that are sprayed onto a surface. Made from commercially ...

To use a smaller antenna, we need a higher signal frequency, and that’s what we do when we apply modulation to the signal. Modulation is simply encoding the low frequency signal in the information of ...

Forbes contributors publish independent expert analyses and insights. I write about all things space -- exploration, astronomy and more. Artist's impression of the European Space Agency's Biomass ...

Placing an antenna in a design always needs care, but when there are two or more antennas in the design, it is even more important to understand how the antennas radiate, how they will perform ...

ADELPHI, Md.-- Army and university researchers collaborated to develop a controller for deploying robots, which forms antenna arrays to maintain longer-range wireless communication. Antennas are ...

TV antennas are having something of a renaissance in the U.S. Buoyed by the ever-increasing costs of cable and streaming subscriptions, and additional channels enabled by the advent of digital TV, ...

Qualcomm said recently it has developed breakthrough antenna technology that will help power uber-fast speeds in next-generation 5G smartphones. The San Diego company highlighted several antenna ...

As 5G networking inches closer to reality, one of the more stubborn problems also will be one of the smallest. Several issues have yet to be cracked with beamforming and massive MIMO antennas, which ...
