A typical sensor node has a transmit duty cycle of 3% and draws a current of 1.53 mA while it is in the active part of the duty cycle, and negligible current while in the inactive part of the duty cycle. On average, the node sends 375 bits of data per transmission and each transmission takes 33.0 ms.
- i.How long does each node transmit for in every hour? Express your answer in seconds.
- ii.If each sensor node has a battery with a capacity of 2510 mAh, how long a transmission is this battery capable of powering before it must be recharged or replaced? Express your answer in seconds in scientific notation.
- iii.At what data rate is data transferred in each transmission? Express your answer in kbps.
