NB-IoT dictionary
Narrowband-IoT or NB-IoT, just like it’s name, is packed with terminology. We created an overview of the jargon by providing this keyword dictionary. Helping to demystify Narrowband IoT. Giving an understanding of all it’s different components.
The uppermost layer on the control plane of the access stratum is radio resource control (RRC) (AS). It also transports non-access stratum (NAS) messages, which are positioned above the RRC layer. The RRC layer contains a number of information components that make up system information.
The Master Information Blocks (MIBs) contains the most important and often communicated system information.
The NB-IoT RACH procedure is a lower power state, where it can conserve its battery life by entering idle mode. The NB-IoT RACH procedure is based on the IEEE 802.11ah standard.
The NPDSCH channel transports unicast data from an eNB (base station) to an NB-IoT device.
Narrowband Reference Signal (NRS) is used for cell search and initial system acquisition. It's utilized to allow the device to estimate the downlink channel.
The Narrowband Secondary Synchronisation Signal (NSSS) provides time and frequency synchronisation of user equipment in a cellular network.
NB-IoT Physical Broadcast Channel (NPBCH) is used to carry MIB information to the device in the downlink by eNB (base station).
The Narrowband Primary Synchronization Signal (NPSS) is transmitted continuously at the lowest possible power level.
The NB-IoT Synchronization Signals are used for synchronization between the distributed systems. It includes the synchronization of the data packets.
Main purpose of PSM
To decrease the data usage on your device and to extend battery life.
With the advent of IoT, the need to connect devices with networks has increased exponentially. However, these devices are deployed in remote areas with no wireless coverage.
NB-IoT is an enhanced narrowband data transmission protocol designed for IoT devices. The NB-IoT protocol is optimized to deliver lower data rates but with improved security and longer battery life.
