DW1000 Anchor and tag receive data failure rate

[size=small][font=新細明體][size=medium]When we use the DW1000 to test the RTLS system, if the TAG is to close to the Anchor, it is found that the failure rate of ANCHOR receiving data is high, between TAG and Anchor distance is closer, the failure rate is higher. However, if the TAG far from ANCHOR, (maybe 2 meters or more), the ANCHOR receive data rate completely successful and correct. What is the cause of this?[/size][/font][/size]
