Automatic Link Establishment, commonly known as ALE, is the worldwide de facto standard for digitally initiating and sustaining HF radio communications. ALE is a feature in an HF communications radio transceiver system that enables the radio station to make contact, or initiate a circuit, between itself and another HF radio station or network of stations. The purpose is to provide a reliable rapid method of calling and connecting during constantly changing HF ionospheric propagation, reception interference, and shared spectrum use of busy or congested HF channels.
In radio communication, a transceiver is an electronic device which is a combination of a radio transmitter and a receiver, hence the name. It can both transmit and receive radio waves using an antenna, for communication purposes. These two related functions are often combined in a single device to reduce manufacturing costs. The term is also used for other devices which can both transmit and receive through a communications channel, such as optical transceivers which transmit and receive light in optical fiber systems, and bus transceivers which transmit and receive digital data in computer data buses.
High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters. Frequencies immediately below HF are denoted medium frequency (MF), while the next band of higher frequencies is known as the very high frequency (VHF) band. The HF band is a major part of the shortwave band of frequencies, so communication at these frequencies is often called shortwave radio. Because radio waves in this band can be reflected back to Earth by the ionosphere layer in the atmosphere – a method known as "skip" or "skywave" propagation – these frequencies are suitable for long-distance communication across intercontinental distances and for mountainous terrains which prevent line-of-sight communications. The band is used by international shortwave broadcasting stations (3.95–25.82 MHz), aviation communication, government time stations, weather stations, amateur radio and citizens band services, among other uses.
Telefunken was a German radio and television producer, founded in Berlin in 1903 as a joint venture between Siemens & Halske and the Allgemeine Elektrizitäts-Gesellschaft (AEG).
The Boxer is a multirole armoured fighting vehicle designed by an international consortium to accomplish a number of operations through the use of installable mission modules. The governments participating in the Boxer programme have changed as the programme has developed. The Boxer vehicle is produced by the ARTEC GmbH industrial group, and the programme is being managed by OCCAR. ARTEC GmbH is based in Munich; its parent companies are Krauss-Maffei Wegmann GmbH and Rheinmetall Military Vehicles GmbH on the German side, and Rheinmetall Defence Nederland B.V. for the Netherlands. Overall, Rheinmetall has a 64% stake in the joint venture.
Bowman is the name of the tactical communications system used by the British Armed Forces.
PACTOR is a radio modulation mode used by amateur radio operators, marine radio stations, military or government users such as the US Department of Homeland Security, and radio stations in isolated areas to send and receive digital information via radio.
Link 22 is a secure digital radio link in the HF and UHF bands, primarily used by military forces as a tactical data link.
Clansman is the name of a combat net radio system (CNR) used by the British Army from 1976 to 2010.
Barrett Communications is a specialist manufacturer and supplier of commercial high frequency (HF), tactical HF and very high frequency (VHF) communications equipment. Its head office for design and manufacturing is located in Perth, Western Australia. Barrett was acquired by Motorola Solutions in 2022.
Rohde & Schwarz GmbH & Co KG is an international electronics group specializing in the fields of electronic test equipment, broadcast & media, cybersecurity, radiomonitoring and radiolocation, and radiocommunication. The company provides also products for the wireless communications, electronics industry, aerospace and defense, homeland security and critical infrastructures.
During World War II, the German Army relied on an diverse array of communications to maintain contact with its mobile forces and in particular with its armoured forces. Most of this equipment received the generic prefix FuG for Funkgerät, meaning "radio device". Occasionally the shorted Fu designation were used and there were exceptions to both these systems. Number ranges were not unique across the services so sometimes different equipment used by different services had the same FuG prefix. This article is a list and a description of the radio equipment.
E-LynX is a product family of digital military radio equipment from Telefunken Radio Communication Systems GmbH & Co. KG, the German subsidiary of the Israeli Elbit Group. The system is used by several forces like the Nederlandse krijgsmacht, the Swiss Army, the Indian Forces and other. Up from 2019, the Army of German Bundeswehr equipped its forces with E-LynX PNR 1000 in a portable and vehicle version.
Soveron is the brand of a tactical millitary communication system of German Rhode & Schwarz. It is used by the Portugese, Canadian and German armed forces.
The communications systems of the German armed forces (Bundeswehr) include the strategic communication, information systems for the command and control of combined arms forces. It also covers military intelligence, weather forecasting, and aviation of all branches of the German armed forces.
SATCOMBw is the German Bundeswehr's satellite communications system. The system was introduced in 2008; the current "Stage 2" has been in operation since the end of 2011, the system is based on the two communications satellites. The system is operated by Airbus Defense and Space. In 2022 the Budget Committee of the German Bundestag released the funds for the extension of the operator contract with Airbus as part of a 25 million euro proposal until 2028.
