M 2 M ? Io. T Overlap Boundaries not exact Specific areas exist Io. T: objects/things that may or may not be in M 2 M relationship with an ICT system. Example: Passive object (RFID), not able to communicate directly. M 2 M relationship ends with the scanner capable of reading the RFID. 2015 -02 -27 M 2 M Communication 5

Network misalignment Current stage of M 2 M deployments is mainly wireless/cellular network. Advantages of using cellular: “built-in features” authentication / security / (tracking) In some cases mobility Misalignment: Currently used NWs are optimized for different requirements. Not designed for that many devices. Most (~90%) deployed devices are stationary, do not require roaming capability or location tracking (which is cumbersome and waste radio resources and power). Not designed for that kind of usage/traffic. Small amounts (nx 100 B) of data, enormous control overhead (handshakes for radio access / authentication / security / IP address / Qo. S params / …; data bearer establishment and teardown 20+ handshakes + TCP handshakes) 2015 -02 -27 In some cases (Smart Grid) latency < 10 ms M 2 M Communication 14 [1] p. 8. , p. 14 -15. ,
