Vodafone announced on Wednesday rollout plans for its NarrowBand Internet of Things (NB IoT) network, which will start in four European countries next year. The dedicated IoT network will go live in Germany, Ireland, the Netherlands, and Spain in the first quarter of 2017.

NarrowBand is a low-power, wide-area network (LPWAN) technology that uses licensed spectrum to provide communications over long distance. This type of networking is useful for enterprise IoT projects, like agriculture and factories, where normal wireless service is either unavailable or expensive. Vodafone has been one of the largest backers on NarrowBand, an evolution of Huawei’s NB-CIoT effort.
