Narrowband – Internet of Things (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.

New physical layer signals and channels are designed to meet the demanding requirement of extended coverage – rural and deep indoors – and ultra-low device complexity. Initial cost of the NB-IoT modules is expected to be comparable to GSM/GPRS. The underlying technology is however much simpler than today’s GSM/GPRS and its cost is expected to decrease rapidly as demand increases.

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 identification. The first NB-IoT commercial launches have been completed and global roll out is expected for 2017/18.

What is the GSMA NB-IoT Forum?

The GSMA NB-IoT Forum aims to provide all industry and wider ecosystem stakeholders with market representation to accelerate the wide-spread adoption of 3GPP-based NB-IoT technology. NB-IoT is addressing the low power wide area IoT market opportunity using licensed spectrum with the intent to scale global deployment in 2018/19. The Forum Chair is Luke Ibbetson, Vodafone Group and Vice- Chairs are Madame Huang Yuhong of China Mobile, Daniel Herb of T-Mobile US and Jens Olejak of Deutsche Telekom.


What are the objectives of the Forum?

  • Facilitate commercial launches of NB-IoT solutions globally
  • Lead industry partners and the ecosystem to build a strong end-to-end industry chain for future growth and development of NB-IoT
  • Drive and proliferate NB-IoT applications in vertical markets for new business opportunities
  • Promote collaboration between all NB-IoT industry partners to ensure interoperability of solutions.


How to join the GSMA NB-IoT Forum

The GSMA NB-IoT Forum is open to GSMA Members and Associate Members, however all members must positively contribute to the Forum’s high-level objectives, including promoting and deploying NB-IoT technology and encouraging new service and application development.
