## 5 Case Study
This will cause the drone to maintain transmitting at state 2: ADS-B. The consumed energy is 0.1 mW  
**From point 16 to point 17:** The drone detected a new signal from Wi-Fi. Hence, the available signals are now 4G, satellite, ADS-B, Bluetooth and Wi-Fi. This will cause the drone to stay in state 2: ADS-B. The consumed energy is 0.1 mW  
**From point 17 to point 18:** The drone loses the connection with Bluetooth. Hence, the available signals are now 4G, satellite, ADS-B and Wi-Fi. This results in the drone transmitting at state 2: ABS-B. The consumed energy is 0.1 mW  
**From point 18 to point 19:** The drone loses the connection with 4G. Hence, the available signals are now satellite, ABS-B, Wi-Fi. This will cause the drone to maintain state 2: ADS-B. The consumed energy is 0.1 mW  
**From point 19 to point 20:** The drone loses the connection with Wi-Fi. Hence, the available signals are now satellite and ADS-B. This will cause the drone to maintain state 2: ADS-B. The consumed energy is 0.1 mW  
**From point 20 to point 21:** The only available RF-CS is the satellite. The drone will be in contact with a satellite, which represents state 7: satellite. The consumed energy is 283.1 mW. **From point 21 to point 22:** The drone detected a new signal from Bluetooth. This will cause it to move to state 4: Bluetooth. The consumed energy is 56.7 mW. **From point 22 to point 23:** The drone detected a new signal from Wi-Fi. Hence, the available signals are now satellite and Wi-Fi. This will cause the drone to state 5: Wi-Fi. The consumed energy is 58.1 mW. **From point 23 to point 24:** The only available RF-CS is the satellite. The drone will thus be in state 7: satellite. The consumed energy is 283.1 mW. **From point 24 to point 25:** The drone detected a new signal from ADS-B. This results in the drone moving to state 2: ADS-B. The consumed energy is 0.1 mW. **From point 25 to point 26:** The drone detected a new signal from Wi-Fi. Hence, the available signals are now satellite, ADS-B and Wi-Fi. This will cause the drone to maintain transmitting at state 2: ADS-B. The consumed energy is 0.1 mW. **From point 26 to point 27:** The drone detected another new signal from IoT. Hence, the available signals are now satellite, ADS-B, Wi-Fi and IoT. This will cause the drone to maintain its transmitting at state 2: ADS-B. The consumed energy is 0.1 mW. **From point 27 to point 28:** The drone loses the connection with Wi-Fi Hence, the available signals are now satellite, ADS-B, and IoT. This will cause the drone to maintain its transmitting at state 2: ADS-B. The consumed energy is 0.1 mW. **From point 28 to point 29:** The drone detected another new signal from Bluetooth. Hence, the available signals are now satellite, ADS-B, IoT and Bluetooth. This will cause the drone to maintain transmitting at state 2: ADS-B. The consumed energy is 0.1 mW. **From point 29 to point 30:** The drone loses the connection with IoT. Hence, the available signals are now satellite, ADS-B, and Bluetooth. This will cause the drone to maintain transmitting at state 2: ADS-B. The consumed energy is 0.1 mW. **From point 30 to point 31:** The drone further loses the connection with Bluetooth. Hence, the available signals are now satellite and ADS-B. This will cause the drone to maintain transmitting at state 2: ADS-B. The consumed energy is 0.1 mW. **From point 31 to point 32:** The drone detected a new signal from Wi-Fi. Hence, the available signals are now satellite, ADS-B and Wi-Fi. This will cause the drone to maintain transmitting at state 2: ADS-B. The consumed energy is 0.1 mW. **From point 32 to point 33:** The drone detected a new signal from 5G. Hence, the available signals are now satellite, ADS-B and 5G. The drone continues in state 2: ADS-B. The consumed energy is 0.1 mW. **From point 33 to point 34:** The drone loses the connection with 5G and detects Bluetooth. Hence, the available signals are now satellite, ADS-B and Bluetooth. The drone stays in state 2: ABS-B. The consumed energy is 0.1 mW.
