Q. Consider the following:
1. Cellular Networks
2. Wi-Fi
3. Fiber To The Home (FTTH)
4. Radio Frequency Identification (RFID)
5. Near-Field Communication (NFC)
6. Satellite networks
How many of the above are parts of Machine-to-Machine (M2M) services?
Answer: C
Notes:
Explanation – Machine-to-Machine (M2M) services encompass a range of technologies that enable devices to communicate with each other without human intervention. Examples include: Cellular Networks, Wi-Fi, Radio Frequency Identification (RFID), Bluetooth, Near-Field Communication (NFC), Satellite Communication, Wireless Sensor Networks (WSNs). However, Fiber To The Home (FTTH) is not associated with M2M services, as it is primarily used for providing high-speed internet access to residential users rather than facilitating machine-to-machine communication.
