In practical range testing outdoors with line-of-sight (LOS) and use of the wireless dimmer
application example, the following range has been verified at Chipcon Norway with optimal
SmartRF Studio settings for the respective data rates:
1. Data rate settings 250 kbps, range measured: 170 meters
Please note that these range tests were performed with a simple packet protocol, no link
margin, no robust protocol, close to the sensitivity limit of CC2420, and no retransmission.
