Rohde & Schwarz, Narrowband Internet of Things

Narrowband Internet of Things
Whitepaper
As part of Release 13, 3GPP has specified a new radio interface, the Narrowband Internet of Things (NBIoT).
NB-IoT is optimized for machine type traffic. It 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 NBIoT
is an independent radio interface, it is tightly connected with LTE, which also shows up in its integration
in the current LTE specifications.
In this whitepaper we introduce the NB-IoT technology with an emphasis on the tight connection to LTE.
