Cat-M, EC-GSM and NB-IoT are the 3GPP IoT solutions for operation in licensed spectrum first included in release 13. They are all capable of supporting the first wave of IoT use cases requiring 15-20 dB extended coverage as compared to today’s baselines GSM and LTE, +10 years battery life times and a low device cost.
The technology choice depends on the operator network evolution plans and current coverage, as well as selection of primary use cases. Cat-M is complementary to the other technologies by offering additional capabilities.
In all three cases the Ericsson offering enables extensive reuse of site assets such as radio and modern baseband units, as well as pooling of computational resources. The solution is designed to support efficient coexistence of MBB and IoT traffic.
The Ericsson Massive IoT RAN solution in combination with the IoT core network portfolio enables separation of resources for MBB and IoT as well as the flexibility and scalability needed for the predicted growth of IoT.
