Common use of Channel sampling Clause in Contracts

Channel sampling. The users first place Xxxxx and Xxx and the distance between their NIC cards is < 5cm. A user then starts the TDS program on Xxxxx and makes Xxxxx an initiator. Xxxxx sends a message to other devices and ask them (including Xxxxx) to start listening to a same public WiFi source. Current WiFi standard uses orthogonal frequency-division multiplexing (OFDM) and there are 56 orthogonal subcarrier signals to carry data on parallel data streams. Hence at a same time, the CSI measurement of a WiFi source includes up to 56 sample values from different sub-carriers. Figure 5 shows samples of amplitude values from three sub-carriers of a same WiFi source. Note that Xxxxx and Xxx have highly correlated sample values, but Xxx’s measurement is very different to theirs.
