11ac MCS9 40MHz 7 0.540 W
11ac MCS9 80MHz 6 0.467 W
Note Continuous Rx
Continuously receiving data (continuous Rx) in test mode has almost no effect on the power
consumption of the module. In real transmissions, there won't be a continuous reception use case
because the system will be always transmitting some synchronization data when receiving, and the
power consumption will be increased as observed in Power consumption: Real wireless transmission
(but never as much as when transmitting).
Note These power consumption numbers should be considered guidelines only, never as fixed or
absolute values. Actual values will depend entirely upon individual setup and system application.
Power consumption: Real wireless transmission
The following plot shows the power consumption of the ConnectCore 6UL VSYS power domain during
a real wireless transmission:
The power consumption increase of the real wireless transmission is calculated by taking the mean
power consumption value of the transmission and receiver bursts:
Power consumption increase
Transmission 0.849 W
Reception 0.279 W
As expected, the transmission power consumption is lower than the maximum observed in the tables
above on the 802.11g/n mode (0.976 W in 11g/n MCS0 20MHz). In a real wireless transmission,
modulation and bandwidth are configured automatically.
