Abstract: A system for forming beams that are suited to a given coverage, has at least the following elements: a configuration manager, a set of modems in contact with switches, multiplexers for multiplexing the modems by group onto as many intermediate ports each corresponding to a beam, a module for forming pathways generating a number of pathways distributed about the axis of the antenna, a phase-shift module for the beams of each of the pathways, a power transposition-amplification module and at least two antennas connected to said transposition-amplification module. For the reception part, the system comprises a set of modules that are identical with the exception of the transposition-amplification module, which carries out the low-noise reception and the transposition.
Abstract: A very high speed SHF-EHF radio system having a very large capacity of several gigabits comprises at least one ultra-wideband base station and an ultra-wideband and multiuse terminal for very high speed wireless systems providing point-to-multipoint transmission of a plurality of simultaneous waveforms in order to provide a plurality of subscribers or customers of various types with multiple services. The base and the terminal comprise ultra-wideband transmitter/receiver means which are capable of exchanging a plurality of waveforms delivered by multiplexes of various modems. The radio of the base has at least one microwave spectrum generator for the multiplexes optimized for each service and for any type of customer. The transmitter/receiver of the radio of the terminal is suited to operating in the subband of the downlink channel and in at least one of the two-way subbands.
