This innovation has been particularly true in communications, as Radio Frequency (RF) technology is found everywhere in daily life. RF technology is critical to many aspects of modern electronics as ...

The US government lays claim to a large chunk of spectrum for military use, communications, and transportation. FM radio operates between 88 and 108.0 MHz, and AM radio operates between 540 and ...

A new quantum sensor can analyze the full spectrum of radio frequency and real-world signals, unleashing new potentials for soldier communications, spectrum awareness and electronic warfare.

Army researchers built the sensor, which can sample the radio-frequency spectrum — from zero frequency up to 20 GHz — and detect AM and FM radio, Bluetooth, Wi-Fi and other communication signals.

Researchers at the Harvard School of Engineering and Applied Sciences have developed a method to wirelessly transmit radio frequency via a semiconductor laser. The breakthrough, published in ...

Students who don't have access to high-speed internet are part of the "homework gap," In Michigan, some will get it via an obscure government radio frequency carrying it to the Upper Peninsula.
