An air-to-ground radiotelephone technology demonstration occurred during 1923 Toulouse Air Show at Francazal and Montaudran airports, in France. [2] The first recorded air-to-ground radiotelephone service on a scheduled flight was in 1937 on the Chicago-Seattle route by Northwest Airlines. [3] [failed verification]
Gogo's air-to-ground (ATG) network is a cellular radio network (meaning that there is a hand-off when the aircraft moves between service areas) that has more than 200 towers in the continental U.S. and Canada. [13] The ground stations consist of original Airfone air-ground phone relay stations and newer locations, using the 850 MHz ATG band.
In 1917 AT&T invented the first American air-to-ground radio transmitter. They tested this device at Langley Field in Virginia and found it was a viable technology. [ 5 ] In May 1917, General George Squier of the U.S. Army Signal Corps contacted AT&T to develop an air-to-ground radio with a range of 2,000 yards.
Example of an ACARS message. In aviation, ACARS (/ ˈ eɪ k ɑːr z /; an acronym for Aircraft Communications Addressing and Reporting System) is a digital datalink system for transmission of short messages between aircraft and ground stations via airband radio or satellite.
Particularly in Air-to-Air (A2A) and Air-to-Ground (A2G) channels, where Line-of-Sight (LOS) propagation predominates, a Ricean distribution is a more appropriate model. [5] Additionally, other models like Nakagami , chi-squared ( χ 2 {\displaystyle \chi ^{2}} ), and non-central χ 2 {\displaystyle \chi ^{2}} distributions are also considered ...
The Aeronautical Telecommunication Network [1] (ATN) is an internetwork architecture that allows ground/ground, air/ground, and avionic data subnetworks to interoperate by adopting common interface services and protocols based on the ISO OSI Reference Model.

Multifunctional Information Distribution System (MIDS) is the NATO name for the communication component of Link-16.. MID is an advanced command, control, communications, computing and intelligence system incorporating high-capacity, jam-resistant, digital communication links for exchange of near real-time tactical information, including both data and voice, among air, ground, and sea elements.
