Abstract: A method of securing radio communication between a ramp agent and an aircraft provided with a base station adapted to transmit a beacon signal includes establishing a first database identifying organizations such as aircraft operators and authorized service providers; for each organization, establishing a second database identifying the ramp agents that it employs and associating biometric data with each ramp agent; providing the ramp agent with a terminal; and when attempting to establish communication between the ramp agent and the aircraft, performing two checks relating firstly to the identity of the ramp agent and secondly to the ramp agent's employer organization in order to verify whether the agent is indeed authorized to establish such communication.

Abstract: A light for mounting on an aircraft is fitted with a light source, an antenna for establishing radio communication between the aircraft and a ramp agent, or airport equipment, or an airport vehicle, and connection means for connecting a signal cable for linking the antenna to radio communication means of the aircraft.

Abstract: Method of detecting the operation of a device for transmitting voice signals between two equipment items so that at least one of the equipment items can send a voice signal and the other equipment item can receive this voice signal, the equipment items being linked by a wireless transmission chain, the method comprising, during a voice signal transmission phase, the steps of: detecting on the sending equipment item a presence of a voice signal on transmission, and generating in response a voice presence on transmission signal; detecting on the receiving equipment item a presence or an absence of a voice signal on reception, and generating in response a signal indicating voice on reception; transmitting the signal indicating voice on reception from the receiving equipment item to the sending equipment item; comparing in the sending equipment item the voice presence on transmission signal and the signal indicating voice on reception, and triggering an alarm if the compared signals are not consistent.

Abstract: The invention relates to a mobile container fitted with a management module comprising a memory and: a break-in detection member for detecting attempts at breaking into the mobile container, the management module being adapted to store time-and-date stamped break-in information in the memory on each occasion that the break-in detection member detects a break-in or an attempted break-in; and a first communications module for dialoguing with a terminal and connected to the memory to send the break-in information stored in the memory to the terminal as soon as communication is set up with the terminal. The container is also fitted with a second communications module suitable for dialoguing with radio frequency labels carried by articles contained in the container.

Abstract: The invention concerns a radio communication device comprising a base station installed on a vehicle and at least a mobile station in the possession of a residence subscriber located on a site, and said radio communication device is operated by detecting in the base station when the vehicle reaches a site available time windows then by transmitting into these time windows a signal representing the vehicle identity.
