Description |
|---|---|
QUAD |
TN selects up to 4 measurements of ANs from 4 quadrants for the best TN location calculation |
RSSI |
TN selects up to 4 measurements of ANs with highest RSSI |
Round robin |
TN takes turn to select up to 4 measurements from all ANs in it’s anchor list in the round robin manner. (e.g: anchor list has 6 ANs (1,2,3,4,5,6), each round TN selects measurements of ANs: (1,2,3,4), (5,6,1,2), (3,4,5,6) … |
