the Decawave DW1000 datasheet rev. 2.18 has on the front page
“Extended communications range up to 290 m @ 110 kbps 10% PER minimises required infrastructure in RTLS”
And the DWM1001Dev System overview states
"The DWM1001 range is up to 60 meters (point to point) for the best antenna orientation and with ideal line of sight conditions.
Our initial experiments with DWM1000 give OATS range of around 60m for blink messages with acceptable SNR.
Nothing like the 200+ meters claimed by the chip datasheet
Can anybody explain the discrepancy?
