Abstract:
1. A very high speed Super High Frequency-Extremely High Frequency (SHF-EHF) radio system having a very large capacity of an order of Gigabits per second, and comprising at least one ultra-wideband base station and an ultra-wideband and multiuse terminal for very high speed wireless systems, with a data rate of hundreds of Megabits per second, providing point-to-multipoint transmission for a plurality of simultaneous services including multimedia, very high speed internet access, backhaul for base stations, video surveillance, in order to provide a plurality of subscribers or customers of various types with multiple services, comprising: the base station having at least one ultra-wideband transmitter associated with an antenna, an ultra-wideband receiver associated with a reception antenna, the ultra-wideband terminal having at least one ultra-wideband transmitter/receiver associated with an antenna, wherein the base station and the terminal exchange a plurality of waveforms delivered by multiplexing of a plurality of modems, the base station having a radio having at least one microwave spectrum generator for an adaptive wideband channel microwave multiplex optimized for each service and for a plurality of types of customers, and made up of at least one group of channels or downlink subband suited to broadcasting multimedia and to delivering an asymmetric throughput Internet having different upload and download throughputs, and of at least one group of channels or subband for access communications and/or for symmetrical and dynamic communications for backhaul communications and video surveillance, wherein the transmitter/receiver of a radio of the terminal is suited to operate in the downlink subband for groups G1 and G2, and in at least a bidirectional subband for groups G3 and G4, where G1 refers to a first group of service, G2 refers to a second group of service, G3 refers to a third group of service, and G4 refers to a fourth group of service, each said group G1-G4 having a respective bandwidth based upon needs of customers in a given sector, said system being based on a microwave architecture comprising multiplexers and demultiplexers configured to temporally, spectrally, and spatially separate a plurality of groups for multimedia, Internet and video surveillance content, having symmetrical and dynamic, asymmetric data rates and capacities and diversified for a set of various customers in a time division duplex (TDD) mode, wherein the microwave spectrum generator is suited to produce a microwave multiplex of 1 GHz width for contiguous two-way channels allowing dynamic uplink and downlink communications and asymmetric downlink channels, all of these channels operating simultaneously, and has at least the following elements: a first-level device for the groups G1 and G2 one-way links which is placed in parallel with a second-level device for the groups G3 and G4 two-way links, the first-level device for the one-way links is made up of a combiner comprising an output connected to the transmitter of the base station, and an input of the combiner is an output of the various modems, the second-level device for the two-way links is provided by a circulator having an output coupled to a combiner having an output which goes toward the transmitter of the base station and by devices having a function which is the inverse of that of the combiner, or a splitter, said splitter is connected to the receiver of the base station, and the signals from the splitter return to the modems through circulators.
