Machine to Machine (M2M) communication represents a significant growth opportunity for the 3GPP ecosystem. To support the so called 'Internet of Things' (IoT), 3GPP operators have to address usage scenarios with devices that are power efficient (with battery life of several years), can be reached in challenging coverage conditions e.g. indoor and basements and, more importantly, are cheap enough so that they can be deployed on a mass scale and even be disposable.
The study on which this technical report is based has considered both the possibility of evolving the current GERAN system and the design of a new access system to meet the requirements for a Cellular IoT system for the lower data rate end of the M2M market. A summary of deployment scenarios and requirements that are relevant for Cellular IoT is provided in Annex A.
Techniques captured in this report have been developed based on the assumption that Cellular IoT devices require very low throughput, do not have stringent delay requirements like those required for real time services, do not need to support circuit switched services, do not need to support Inter-RAT mobility and will perform intra-RAT mobility by cell reselection.
