The radiated pattern for the PCB antenna was measured with the horizontal polarization
direction for the CC2400DB by measuring with vertical and horizontal mounting of the
demonstration board.
Important:
In practical range testing outdoors with line-of-sight (LOS) and use of the rfBlinkLed
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 1 Mbps, range measured: 140 meters
2. Data rate settings 250 kbps, range measured: 240 meters
Please note that these range tests were performed at 0
°
C with a simple packet protocol, no
link margin, no robust protocol, close to the sensitivity limit of CC2400, and no retransmission.
