1. Scenario 1: Device Wake up to Poll Coordinator (No data from Coordinator)
Device wakes up
Device Transitions to Receive Mode
Device Performs one CCA
Device Transitions to Transmit Mode
Device Transmits a Poll packet
Device Receives an No_Data Acknowledge
Assuming the Acknowledge is received, goes back to sleep

2. Scenario 2: Device Wake up to Poll Coordinator (Have data from Coordinator)
Device wakes up
Device Transitions to Receive Mode
Device Performs one CCA
Device Transitions to Transmit Mode
Device Transmits a Poll packet
Device Receives an Acknowledgement with data available
Wait 192us
Receive the data packet from coordinator
Device Transmits an acknowledgement

3. Battery Self Leakage: 0.5% per month
10% of the time
there is data
20% of the time
there is data
Battery Capacity = 2000 mAH
Battery Self Leakage: 0.5% per month
Length of the Event: 6.3ms to 7.2 ms
Active current: 25mA
Sleep mode current: 2uA
(The channel is clear, i.e. TRX does one CCA per attempt)
