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.

5G IoT Forum

The 5G IoT Forum is to provide all industry and wider ecosystem stakeholders with market representation to accelerate the wide-spread adoption of 3GPP-standard 5G technologies including Mobile IoT (LPWA)LTE-M and NB-IoT technologies and evolve to Massive IoT. In the Forum we will discuss issues facing the IoT Industry and make proposals to the 5G IoT Strategy Group. Members are encouraged to participate in the Action Groups. The work of the Action groups will be disseminated to the Forum and members encouraged to adopt the work. Members can also agree to work on Concepts together for the GSMA Foundry.

The objectives of the 5G IoT Forum
  • Encourage information sharing that will lead to growth of cellular based IoT
  • Promote 5G IoT technologies through a pool of centralised industry resources
  • Enable new contributors the ability to join the 5G IoT Action groups
  • Adopt the work of the 5G IoT Action groups in your organisation
  • Create a PoC in GSMA Foundry
How to join the 5G IoT Forum

All GSMA members are welcome to join the Forum. Contact for details.
