this is not a real question but a way to talk about the following topic. I was thinking on a monitoring system based on a Sensor part, a Computing part and a Radio Transmission part.
My question is how much is the power impact of the radio part compared to the power consumption of the sensor part or the computing part? If I want to answer myself I think it depends on the specific Radio tecnology consumption in idle state or active, the sampling rate, the type of sensor I want to use, if I use a microcontroller based unit or a microprocessor one.
Am I right? What can you tell me more about this? Any good book or article to read about this topic?
