CC2652R: Calculating rough power consumption

Part Number: CC2652R
Other Parts Discussed in Thread: LAUNCHXL-CC26X2R1

I am trying to estimate rough power consumption of CC2652 in Zigbee mode .To do that I need "Data Transmission Time" of an end node and typical "Packet Size" . I doubt If I could Calculate the power consumption using just Data Transmission Time because I think there may be other delays in transmission or any reception after transmission !!!

I am not talking about other times like process , sleep or measure in a typical cycle currently!

An other question I have is about current drawing in a router when it is receiving ! Does it draw for example 7mA (receive current) all the time or it draws current in an interval?

1. I suppose you can use power analyzer to measure this by yourself.
2. The receiver of router is always turned on so it will always consume ~7mA (receive current).

Hi
How can I find power analyzer ?

Try to refer to www.ti.com/.../swra478d.pdf or if you use LAUNCHXL-CC26x2R1, you can try to use energy tracy in CCS to do power consumption measurement.

No, I don't want to measure it !
I just want to calculate a rough value .
