Multi-user null data packet (ndp) ranging |
| abstract |
A first communication device prompts a plurality of second communication devices to transmit, during a contiguous time period reserved for a range measurement exchange, respective first null data packets (NDPs) at respective times. The first communication device receives first NDPs from at least some of the second communication devices during the contiguous time period, and transmits one or more second NDPs to the plurality of second communication devices. The first communication device uses reception of the first NDPs and transmission of the one or more second NDPs to determine respective ranges between the first communication device and respective second communication devices. |
