Future Aspects
What is M2M M2M (ETSI TC M2M) - Communication between two or more
entities that do not necessarily need any direct human intervention
MTC (3GPP SA2 SIMTC) - A form of data communication which involves one or more entities that do not necessarily need human interaction
M2M (IEEE 802.16p) - Information exchange between a Subscriber station and a Server in the core network (through a base station) or between Subscriber station, which may be carried out without any human interaction.
Main Objectives Create a survey on the required features in LTE
or LTE – A network to support an M2M functionalities.
Demonstrate a few of those additional features in using multiple simulation platforms.
Demonstrate real time scenario to support the model.
