eMTC, often called LTE-M, or LTE-MTC, is a low power wide area (LPWA) technology standard published by 3GPP in the Release 13 specification. eMTC is a low power wide area technology which supports IoT through lower device complexity and provides extended coverage, leveraging a mobile carriers existing LTE base stations. eMTC finds its place as a (comparatively) high data rate service for more data-hungry IoT applications.
eMTC is simply an amendment to the existing LTE standard, with Release 13 specifying a brand new Cat-M1 UE capable of operating on a bandwidth 1.08 MHz (i.e., 6 PRB's) within an existing LTE deployment, or 1.4 MHz in standalone deployment. This is a significant development from previous Release 12 specification of LTE Cat-0, which while containing a number of simplifications from conventional UE, still had to operate on standard LTE channel bandwidths.
Cat-M1 allows an extended battery life of more than 10 years for a wide range of machine type communication use cases through the use of power saving mode (PSM), Discontinuous Reception (eDRX), Cellular IoT (CIoT) control plane, and user plane EPS optimisations for small data transmission.
Supported by all major mobile equipment, chipset and module manufacturers, eMTC networks will co-exist with 2G, 3G, and 4G mobile networks and benefit from all the security and privacy features of mobile networks, such as support for user identity confidentiality, entity authentication, confidentiality, data integrity, and mobile equipment identification.
