high-frequency data
1High frequency — (HF) radio frequencies are between 3 and 30 MHz. Also known as the decameter band or decameter wave as the wavelengths range from one to ten decameters (ten to one hundred metres). Frequencies immediately below HF are denoted Medium frequency… …
2High Frequency Internet Protocol — High Frequency Internet Protocolacronyms: HFIP or HF IP. Usually associated with Automatic Link Establishment and HF radio data communications. HFIP provides protocol layers enabling internet file transfer, chat, web, or email. HFIP commonly uses …
3High Frequency Active Auroral Research Program — HAARP is often confused with Project HARP, the High Altitude Research Project (a joint project of The Pentagon and the Canadian Department of National Defence).The High Frequency Active Auroral Research Program (HAARP) is an investigation project …

5Super high frequency — (or SHF) refers to radio frequencies (RF) in the range of 3 GHz and 30 GHz. Also known as the centimeter band or centimeter wave as the wavelengths range from ten to one centimeters.DescriptionThe International Telecommunication Union (ITU), an… …
6Clustering high-dimensional data — is the cluster analysis of data with anywhere from a few dozen to many thousands of dimensions. Such high dimensional data spaces are often encountered in areas such as medicine, where DNA microarray technology can produce a large number of… …
7Advanced Extremely High Frequency — The Advanced Extremely High Frequency (AEHF) system will provide connectivity across the spectrum of mission areas, including land, air and naval warfare; special operations; strategic nuclear operations; strategic defense; theater missile… …
8High-speed multimedia radio — (HSMM), colloquially referred to as the hinternet , is the implementation of wireless data networks over amateur radio frequencies using commercial off the shelf (COTS) hardware such as 802.11 access points and D Star equipment. Licensed amateur… …
9Data compression — Source coding redirects here. For the term in computer programming, see Source code. In computer science and information theory, data compression, source coding or bit rate reduction is the process of encoding information using fewer bits than… …
10Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… …
