The Internet has always been used for machines to communicate with each other, not just humans communicating with machines. The number of possible applications extended further with the introduction of mobile communications. This machine type communication (MTC) is also called machine to machine communication (M2M) or just Internet of Things (IoT). Many features targeted at IoT have been already standardized up to LTE Release 12.

With the introduction of 3GPP Release 13 MTC was further developed to eMTC – CAT-M1. In addition a new standard dedicated for IoT has been developed which is called narrow band internet of things (NB-IoT / CAT-NB1). NB-IoT is based on LTE Release 13 but with fundamental changes and therefore regarded as new radio access technology.

This seminar explains the specific requirements for an IoT device and the challenges for a mobile communication network supporting IoT devices.

This seminar also explains the technical details of the two solutions, the LTE R13 eMTC and the new R13 Standard NB-IoT.

The participants should be familiar with LTE R8.
