Time-reversal wireless paradigm for internet of things

摘要: A method of connecting devices to a network is provided. The includes providing base stations connected network, and at each the stations, receiving probe signals from terminal devices. For devices, station calculates signature waveform based on time-reversed channel response signal derived corresponding signal. determines downlink transmit for device data waveform, transmits Several have overlapping broadcast regions, several are located within overlapped using same frequency band, some transmitted by having regions also overlap in time.
