Shortwave bands - Shortwave bands are frequency allocations for use within the high frequency radio spectrum. They are the primary medium for applications such as marine communication, international broadcasting, and worldwide amateur radio activity because they take advantage of ionospheric skip propagation to send data around the world.
High-energy radio-frequency weapons - High Energy Radio Frequency weapons (HERF) or High Power Radio Frequency weapons (HPRF) are weapons that use high intensity radio waves to disrupt electronics. They operate similarly to EMP devices, by inducing destructive voltage within electronic wiring.
Tuned radio frequency receiver - A radio receiver comprised of several tuned radio-frequency amplifiers followed by circuits to detect and amplify the audio signal. Used in the early 20-th century, it is difficult to operate because each stage must be individually tuned to the station's frequency.
Amateur radio frequency allocations - Amateur radio frequency allocation is done by national telecommunications authorities. Globally, the ITU oversees how much radio spectrum is set aside for amateur radio transmissions.
Texas Instruments Radio Frequency Identification System (TIRIS) - Develops and manufactures transponder, reader and antenna products for business, industrial and consumer applications. Includes product, software and evaluation kit specifications, application notes and photographs and software available for download.
Information Technology and Telecommunications Laboratory (ITTL) - Part of the Georgia Tech Research Institute (GTRI). ITTL performs research in Internet and database technologies and applications; broadband, defense, radio frequency and wireless communications; network applications and security issues; mapping/geographical information, distributed simulation and enterprise information systems; and product research and development, manufacturing preparation and other steps ...
The Data Communications Committee - Responsible for the issue of the "Notice of Variation" required by law for running an internet gateway. Contains news, an online application form and information on frequencies available.
