What is the application used for air to ground communication?
Voice/audio communications between an aircraft and the ground are traditionally accomplished using radio telephony, broadcasting and receiving on: UHF. VHF. HF.
What are different aircraft communication systems?
The system is also responsible for recording communications and cabin audio. It includes the following: • Audio integrating system; • Communication radios; • Radio tuning system; • Cockpit voice recorder; and • Static dischargers.
What is land and air mobile communication?
The mobile service is a “radiocommunication service between mobile and land stations, or between mobile stations.”[EN13] This includes the conventional land, maritime, and aeronautical mobile services, common carriers such as cellular telephone and radio paging, and new applications like PCS and elements of the …
What is the air to air frequency?
However, the frequency 123.45 MHz is designated as an air-to-air VHF communications frequency to enable aircraft engaged in flights over remote and oceanic areas out of range of VHF ground stations to exchange necessary operational information and to facilitate the resolution of operational problems.

What is land communication?
Professional Mobile Radio (PMR) also known as Private Mobile Radio and Land Mobile radio (LMR) are person-to-person two-way radio voice communication systems which use portable, mobile, base station, and dispatch console radios.
Which one of the following is the disadvantage of land mobile radio?
On the downside LMR is an inefficient user of scarce radio spectrum, so professional organizations sometimes struggle to find available frequencies. One consequence is that spectrum authorities have reduced LMR bandwidth in order to squeeze more users into limited spectrum. As a result, data transmission has suffered.
What is ground frequency?
Typical unicom frequencies are 122.7, 122.72, 122.8, 122.97, 123.0. 123.05, and 123.07 MHz. At controlled airports, ground frequencies are likely 121.3, 121.5, 121.7, and 121.9. Note that all begin with 121 and end in an odd tenth.
What are the 4 basic elements of communication?
The communication process is made up of four key components. Those components include encoding, medium of transmission, decoding, and feedback. There are also two other factors in the process, and those two factors are present in the form of the sender and the receiver.
What is a broadband direct-air-to-ground communications (da2gc)?
According to ITU-R M.2282-0, a broadband Direct-Air-to-Ground Communications (DA2GC) system constitutes an application for various types of telecommunication services, such as Internet access and mobile multimedia services, during flights.
What is ground-to-air communications?
Ground-to-air communications through the use of BATS’ Groundstation tracking systems are key components of UAV and manned downlink technology that make video and data livestreaming flights possible.
What are the benefits of broadband to the aviation industry?
In addition to providing advanced passenger communications and entertainment services, airlines can upload and download essential flight data via a broadband connection rather than through time-consuming hard disk data transfers at ground stops. This reduces the time the aircraft needs to spend on the ground, improving its productivity.
Is there a high-bandwidth solution for in-flight broadband?
Despite the satellite and hybrid A2G systems available today, there is still no cost-effective high-bandwidth solution for in-flight broadband – especially for passenger infotainment with video on demand (VoD) and multimedia communications.
