A communication arrangement enables aircraft passengers to use their normal mobile phones for communication with ground-based parties. A mobile phone microcell is established on the aircraft by means of antennas 35 mounted at locations around the aircraft and connected to a base transceiver station BTS...

Every country has a governing authority that allocates a specific operating frequency for a small satellite mission. The International Telecommunication Union (ITU) Radio Regulations regulate the utilization of radio frequencies and the law of nations scale radio-communication services. However, the proces...

In fact, drones operate at different wireless communication frequencies, as illustrated in Table 1, which compares the two main drones communication frequencies, 2.4 GHz and 5GHz. Table 1. Comparison between 2.4 GHz and 5GHz. Parameters2.4 GHz5 GHz Frequency band Lower frequency Higher frequency ...
(calledinfrasonicfrequencies) at distances above 100km from the source. In particular, the Concorde sonic boom has been studied at about 300km, and signals of about 0.6N/m2were received at frequencies of the order of 0.4Hz. The same phenomenon occurs for thunder and explosions on the ground....
aWithin the European Maritime Area and in Canada, these frequencies (channels 10, 67, 73) may also be used, if so required, by the individual administrations concerned, for communication between ship stations, aircraft stations and participating land stations engaged in coordinated search and rescue...
as Airbus we chose Safran Electronics & Defense Beacons, formerly Orolia, to develop its ELT-DT solution while we would complement it with an algorithm hosted in our aircraft’s avionics computers,” recalls Claude Pichavant, Airbus’ Executive Expert for Communication, Navigation and Surveillance...
