Narrowband IoT (NB-IoT) could be a standards-based low power wide area (LPWA) technology developed to creat diverse new IoT devices and services. NB-IoT considerably improves the power consumption of user devices, system capability and spectrum potency, particularly in deep coverage. Battery lifetime of beyond ten years are often supported for many kinds of use cases.
Supported by all major mobile equipment, chipset and module vendors, NB-IoT will co-exist with 2G, 3G, and 4G mobile networks. It also benefits from all the security and privacy characteristics of mobile networks, like supporting for user identity confidentiality, entity authentication, confidentiality, data integrity, and mobile equipment identification. the first NB-IoT commercial launches are completed and world roll out is predicted for 2017/18.
