What is NB-IoT?
NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage. Battery life of more than 10 years can be supported for a
wide range of use cases.
Supported by all major mobile equipment, chipset and module manufacturers, NB-IoT can co-exist with 2G, 3G, and 4G mobile networks. It also benefits from all the security and privacy features of mobile networks, such as support for user identity confidentiality, entity authentication, confidentiality, data integrity, and mobile equipment
Existing cellular networks already offer very good area coverage in mature markets. However, many potential “connected objects” are located in vast remote areas, far away from the next cellular base station. If there is coverage, it is often weak which requires the device transmitter to operate at high power, draining the battery. In addition, cellular networks are not optimized for applications that occasionally transmit small amounts of data. A battery life of several years combined with an inexpensive device cannot be realized on existing cellular standards, as they do not support the required power saving mechanisms.
Mobile devices working on GSM, 3G and LTE are designed for a variety of services, including mobile voice, messaging and high-speed data transmission. However, NB-IoT
applications do not utilize any of this; they just require low-speed but reliable data transfer, and an appropriate level of reliability. Therefore, using cellular devices for low data
rate applications means using devices that are too expensive for the application.
