BT has launched a multi-million-pound NB-IoT network which covers 97% of the UK population. The new network aims to pave the way for more UK smart cities and industries, and is underpinned by BT’s EE mobile network.

BT’s new NB-IoT network will enable low-data-demand assets, such as street lighting or underground water sensors, to be connected over a smart network. BT says this will not only deliver long battery life, but can enhance efficiency and reduce costs, for example by automatically detecting leaks in water infrastructure.

The rollout of the network will allow BT to help fast-track ‘smart cities’ of the future through use cases that include monitoring and optimising energy use, storage, and distribution.

Agriculture will also stand to benefit from IoT connectivity, with BT having previously trialled sensors to monitor haystack temperature and prevent fire risks, as well as safekeeping of livestock through gate sensors.

Chris Keone, MD, Division X at BT, said: “Growing numbers of businesses are beginning to realise the benefits of IoT applications, and our UK-wide NB-IoT network opens up a wide range of connectivity solutions for monitors, sensors, and other smart devices. Whether it’s building the smart cities of the future or reducing carbon emissions, our network will provide customers with the reliability and efficiency they need.”

The network will add to BT’s existing IoT portfolio, which includes eSIMs and IoT national roaming SIMs for UK businesses, offering greater connectivity to customers on the move or in remote locations.
