+ | ====== TDoA Anchor protocol V3 ====== | ||
+ | |||
+ | ===== Design goals ===== | ||
The protocol is designed to be used with a large number of anchors covering a big area. Each anchor has a limited reach and covers only a small area, but by adding more anchors the system can cover an (virtually) unlimited area. At any point in the covered area, 5-10 anchors should be within range of a Tag. | The protocol is designed to be used with a large number of anchors covering a big area.

A TDoA tag is simply an UWB sniffer. A sniffer can use the data in the packets together with the timestamps when packets are received to calculate its position. | A TDoA tag is simply an UWB sniffer.
