Rohde & Schwarz has just published a new whitepaper on Narrowband Internet of Things (NB-IoT).
NB-IoT has been introduced as part of 3GPP Rel-13 where 3GPP has specified a new radio interface. NBIoT is optimized for machine type traffic and is kept as simple as possible in order to reduce device costs and to minimize battery consumption. In addition, it is also adapted to work in difficult radio conditions, which is a frequent operational area for certain machine type communication devices. Although NB-IoT is an independent radio interface, it is tightly connected with LTE, which also shows up in its integration in the current LTE specifications.
The paper contains the necessary technical details including the new channels, new frame and slot structure, new signalling messages including the system information messages, etc. It's a good read.
