Abstract

The present teaching relates to wireless Internet of Things. In one example, a time reversal client is disclosed. The time reversal client comprises a processor, a memory communicatively coupled with the processor, and a set of instructions, when executed by the processor based on the memory, that cause the time reversal client to perform the following steps: communicatively coupling with a time reversal server through a network, obtaining a set of channel state information (CSI), wherein the set of CSI is captured when at least one probing signal is sent from the wireless transmitter to the wireless receiver through a wireless multipath channel associated with a space, and causing the set of CSI to be sent to the time reversal server through the network.
