Wireless partitioned on-board telecommunication network

摘要

The subject matter disclosed herein relates an on-board network with nodes linked by wired links, the on-board network being partitioned into adjacent sub-networks, mutually segregated by security elements. Each sub-network can be equipped with access points allowing mobile terminals to connect to the sub-network by wireless links. The access points of adjacent sub-networks use different communication standards or distinct sets of transmission resources in such a way that the segregation between adjacent sub-networks is preserved.

1. An on-board network on board an aircraft, the network comprising nodes linked by wired links and being partitioned into a plurality of sub-networks, two sub-networks being adjacent if at least one of the wired links them, the wired links between two adjacent sub-networks being each equipped with a security element to segregate the two adjacent sub-networks, wherein at least a first and a second adjacent sub-network are each equipped with at least one wireless access point, and wherein the first and second adjacent sub-networks belong to different communication domains, the access points respectively equipping the first and second adjacent sub-networks using different communication standards or separate sets of communication resources;
wherein the access points equipping any two adjacent sub-networks use a common communication standard and separate sets of transmission resources; and wherein the on-board network re-uses the separate sets of transmission resources every M
