Measurements done to LibreRouter with Core v0.2, MegaBoard v1.1

  • full tx radio with iperf -u -c 192.168.1.119 -b 120M -t 60
  • with connected client running iperf.

Notes:

  • iperf consumes 85% CPU.
  • Baseline: 3.5W@24V (radio_0 and radio_1 down, radio_2 up in ap mode)
  • working with CPU at 90% (while true) drains 0.5W more from baseline
txpower [dBm] total power [W] Radio only estimation [W] (without Baseline + CPU)
0 6.9 2.9
10 7.1 3.0
16 7.5 3.5
20 8.1 4.1
auto (23) 8.5 4.5
