Tre Sverige AB and Comsel System Ltd among the first to use LTE NarrowBand-Internet of Things (NB-IoT) for energy metering.

Tre Sverige AB and Comsel System Ltd co-operate in a project with LTE NarrowBand-Internet of Things (NB-IoT) regarding energy data measurements and -collection in Skåne, Sweden. Tre Sverige delivers communication via NB-IoT and Comsel System delivers metering devices and management of metering data to the project. The NB-IoT smart metering units which are installed for metering data collection and management make this project unique.

NB-IoT is a new technology developed to transfer small streams of data in a highly efficient way, which is exactly what is needed for Internet of Things. Improved coverage and longer standby periods, both with lower power consumption, are some of the technical advantages with NarrowBand. The technology is well suited to be used for energy metering, which is the case in this specific project. Tre Sverige, who delivered the communication, is one of the pioneers in Sweden within NB-IoT.

Comsel System has delivered Zodiac smart metering terminals with support for NB-IoT/M1 to the project. In addition to the NB-IoT/M1-terminals, Comsel also delivered Zodiac 3G-/4G-terminals for smart energy metering. The solution gives the customer a SLA (Service Level Agreement) of up to 100% on average, has a high degree of security and communicates easily through many different communication methods.

“NB-IoT will make a real difference for Internet of Things. Historically, we’ve been in the forefront with new services, and once again we are the first with an important innovation. This is just the beginning of the avalanche of connections and services that this new technology will enable”, says Johan Johansson, CEO at Tre Sverige.

“We have performed field tests together with Comsel System for a couple of months in this smart metering project in Skåne. The tests show that network coverage increases dramatically for locations where it is normally weak, for example in basements and inaccessible locations in sparsely populated areas. It is very interesting to see how the NB-IoT-technology can be used in this context”, says Göran Brandt, Head of IoT/M2M, Tre Sverige AB.

““We are pleased that Tre Sverige has chosen to cooperate with Comsel. It is very delightful that a strong operator such as Tre identifies the advantages of using NB-IoT within our area of knowledge, and we are proud to be among the first to install NB-IoT for smart metering of energy information. We strongly believe in the advantages of NB-IoT for smart metering of energy data. Furthermore, it feels good that our customer recognizes the economical benefit of choosing our solution. Our cooperation with Tre has been very smooth, and we look forward to our future collaboration”, says Kristian Heimonen, CEO at Comsel System Ltd.
