Narrowband – Internet of Things (NB-IoT) – Explained

Internet of Things has a huge role in the current technological development. In today’s time, one cannot imagine any task without the usage of internet. It helps us by making our each task easier. In this article, we will be focusing on Narrowband IoT or NB-IoT, which is known as a wireless communication standard for the IoT. This unique technology relates to the low-power wide-area networks (LPWAN). NB-IoT helps in connecting devices that need small amounts of data, low bandwidth, and long battery life.  NB-IoT focuses on indoor coverage, low cost, long battery life, and high connection density. NB-IoT uses a subset of the LTE standard but limits the bandwidth to a single narrow-band of 200kHz. It uses OFDM modulation for downlink communication and SC-FDMA for uplink communications. IoT applications which require more frequent communications will be better served by NB-IoT, which has no duty cycle limitations operating on the licensed spectrum.

NarrowbandWhat is Massive IoT?

Massive IoT always comes in mind whenever we talk about NB-IoT.  Massive IoT’s name is enough to understand the meaning, it’s about the amount. It deploys immense amount of low-complexity devices that do not need to communicate with great frequency. The main used cases include low-cost sensors, meters, wearables and trackers. Many of these can be deployed in challenging radio environments, such as a basement of a building or on a moving piece of machinery, and will be relied upon to send occasional signals for up to 10 years, without a change of battery. This makes power consumption and conservation critical aspects.
