High efficiency sub-orbital high altitude telecommunications system

摘要

A wireless telecommunications system comprising a plurality of telecommunications nodes (28) that include receivers and transmitters that are located in a sub-orbital plane. The telecommunications signals are broadband digital radio signals which are modulated by code division multiple access spread spectrum technology. The receivers include a plurality of antennae (48) that are operative to receive relatively weak telecommunications signals and which use spatial processing to identify their source so that maximum utilization of the spectrum is made available for use by the telecommunications signals without interference.
