A mobile communications vehicle (MCV) is a specially-equipped vehicle capable of replacing remote radio communication facilities for mobile communications. The vehicle may carry equipment to operate UHF and VHF frequencies. An MCV can be driven to a location to fill in radio coverage gaps or to replace a damaged radio communications tower. Once deployed the MCV operates unmanned.
Many MCVs are equipped with:
Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF).
Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter. Radio waves with frequencies above the UHF band fall into the super-high frequency (SHF) or microwave frequency range. Lower frequency signals fall into the VHF or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, satellite phones, and numerous other applications.
XM Satellite Radio Holdings Inc. (XM) was one of the three satellite radio (SDARS) and online radio services in the United States and Canada, operated by Sirius XM Holdings. It provided pay-for-service radio, analogous to subscription cable television. Its service included 73 different music channels, 39 news, sports, talk and entertainment channels, 21 regional traffic and weather channels, and 23 play-by-play sports channels. XM channels were identified by Arbitron with the label "XM".
The New York City Fire Department, officially the Fire Department of the City of New York (FDNY) is the full-service fire department of New York City, serving all five boroughs. The FDNY is responsible for fire suppression and fire prevention, and is a major provider of EMS services in New York City. Beyond fire suppression and EMS, the FDNY is responsible for a broad range of services, including technical rescue, CBRN defense, and structural collapse response and analysis.
Automatic vehicle location is a means for automatically determining and transmitting the geographic location of a vehicle. This vehicle location data, from one or more vehicles, may then be collected by a vehicle tracking system to manage an overview of vehicle travel. As of 2017, GPS technology has reached the point of having the transmitting device be smaller than the size of a human thumb, able to run 6 months or more between battery charges, easy to communicate with smartphones — all for less than $20 USD.
A mobile data terminal (MDT) or mobile digital computer (MDC) is a computerized device used in emergency services, public transport, taxicabs, package delivery, roadside assistance, and logistics, among other fields, to communicate with a central dispatcher. They are also used to display mapping and information relevant to the tasks and actions performed by the vehicle such as CAD drawings, diagrams and safety information.
The Global Maritime Distress and Safety System (GMDSS) is a worldwide system for automated emergency signal communication for ships at sea developed by the United Nations' International Maritime Organization (IMO) as part of the SOLAS Convention.
Telematics is an interdisciplinary field encompassing telecommunications, vehicular technologies, electrical engineering, and computer science. Telematics can involve any of the following:
OnStar Corporation is a subsidiary of General Motors that provides subscription-based communications, in-vehicle security, emergency services, turn-by-turn navigation, and remote diagnostics systems throughout the United States, Canada, Chile, China, Mexico, Europe, Brazil, Colombia, Argentina and the Gulf Cooperation Council countries.
The history of mobile phones covers mobile communication devices that connect wirelessly to the public switched telephone network.
The Mobile User Objective System (MUOS) is a United States Space Force narrowband military communications satellite system that supports a worldwide, multi-service population of users in the ultra high frequency (UHF) band. The system provides increased communications capabilities to newer, smaller terminals while still supporting interoperability with legacy terminals. MUOS is designed to support users who require greater mobility, higher bit rates and improved operational availability. The MUOS was declared fully operational for use in 2019.
An amateur radio station is a radio station designed to provide radiocommunications in the amateur radio service for an amateur radio operator. Radio amateurs build and operate several types of amateur radio stations, including fixed ground stations, mobile stations, space stations, and temporary field stations. A slang term often used for an amateur station's location is the shack, named after the small enclosures added to the upperworks of naval ships to hold early radio equipment and batteries.
Traffic signal preemption is a system that allows an operator to override the normal operation of traffic lights. The most common use of these systems manipulates traffic signals in the path of an emergency vehicle, halting conflicting traffic and allowing the emergency vehicle right-of-way, thereby reducing response times and enhancing traffic safety. Signal preemption can also be used on tram, light-rail and bus rapid transit systems, to allow public transportation priority access through intersections, and by railroad systems at crossings to prevent collisions.
Mobile radio or mobiles refer to wireless communications systems and devices which are based on radio frequencies, and where the path of communications is movable on either end. There are a variety of views about what constitutes mobile equipment. For US licensing purposes, mobiles may include hand-carried,, equipment. An obsolete term is radiophone.
Australian mobile intensive care ambulances (MICA) are well-equipped ambulances staffed by highly trained paramedics dispatched to emergency situations where patients require a higher level of care than a regular ambulance can provide.
Ford Sync is a factory-installed, integrated in-vehicle communications and entertainment system that allows users to make hands-free telephone calls, control music and perform other functions with the use of voice commands. The system consists of applications and user interfaces developed by Ford and other third-party developers. The first two generations run on the Windows Embedded Automotive operating system designed by Microsoft, while the third and fourth generations runs on the QNX operating system from BlackBerry Limited. Future versions will run on the Android operating system from Google.
The Civil Defence Corps (CDC) was a civilian volunteer organisation established in Great Britain in 1949 to mobilise and take local control of the affected area in the aftermath of a major national emergency, principally envisaged as being a Cold War nuclear attack. By March 1956, the Civil Defence Corps had 330,000 personnel. It was stood down in Great Britain in 1968, although two Civil Defence Corps still operate within the British Isles, namely the Isle of Man Civil Defence Corps and the unrelated Civil Defence Ireland in the Republic of Ireland. Many other countries maintain a national Civil Defence Corps, usually having a wide brief for assisting in large scale civil emergencies such as flood, earthquake, invasion, or civil disorder.
Paksat-1R is a geosynchronous, communications satellite that was manufactured by China Great Wall Industry Corporation (CGWIC) and operated by the Space and Upper Atmosphere Research Commission (SUPARCO), an executive space authority of the Government of Pakistan.
EchoStar Mobile Limited, an Irish company with commercial operations headquartered in the United Kingdom and a data centre based in Griesheim, Germany, is a mobile operator that provides connectivity across Europe through a converged satellite and terrestrial network. EchoStar Mobile is a subsidiary of EchoStar Corporation, a provider of satellite communications devices.
The White House Communications Agency Roadrunner vehicle is an element of every American presidential motorcade. It is also known as the MC2V. The vehicle serves as the communications hub for the motorcade by encrypting duplex radio and streaming video which in turn is beamed up to a military satellite which in turn beams that data back down to a ground entry point and through to the WHCA switchboard.
