Suppose you have an loT device with three modes of operation : - Transmitting: lasting for T=36ms for each message, and consuming 150 mA - Network synchronisation, lasting for 500 us and repeating every 5 seconds, consumes 20 mA - Otherwise in a sleep mode, with current draw of 6 µA 1- How many synchronisation cycles are performed in 24 hours (don't put the units) 2- What is the drawn electric charge (measured in mAh) within 24 hours for the synchronisation activities only (format 0.0000 - don't put the units) 3- What is the drawn electric charge (measured in mAh) required for sending 50 messages per day (format 0.0000 - don't put the units) 4- What is the total drawn electric charge (measured in mAh) within the 24 hours (format 0.0000 - don't put the units)

Suppose you have an loT device with three modes of operation :
- Transmitting: lasting for Tt =36ms for each message, and consuming 150 mA
- Network synchronisation, lasting for 500 us and repeating every 5 seconds, consumes 20 mA
- Otherwise in a sleep mode, with current draw of 6 µA
1- How many synchronisation cycles are performed in 24 hours
(don't put the units)
2- What is the drawn electric charge (measured in mAh) within 24 hours for the synchronisation activities only
(format 0.0000 - don't
put the units)
3- What is the drawn electric charge (measured in mAh) required for sending 50 messages per day
(format 0.0000 - don't put the
units)
4- What is the total drawn electric charge (measured in mAh) within the 24 hours
(format 0.0000 - don't put the units)
