Nokia conducts Finland's first commercial NB-IoT trial with Sonera

Trial on Sonera's commercial network in the 800 MHz frequency band demonstrates potential of 4G using NB-IoT technology to support billions of IoT-connected devices

Nokia conducts Finland's first commercial NB-IoT trial with Sonera

Nokia and Finnish mobile operator Sonera are the latest to trial the newly standardised NB-IoT (Narrowband Internet of Things) low power, wide area network (LPWAN) technology on the carrier’s commercial 4G network. 3GPP completed the specifications for NB-IoT (LTE Cat-NB1) based on an adaptation of LTE technology in June this year.

Today's 4G LTE networks are optimised for Internet connectivity and video streaming to smartphones, tablets and other portable devices. In the IoT world, networks will need to support billions of remote machines requiring instant connectivity to record and share data for industries such as healthcare, energy, manufacturing, agriculture and transportation.

Unlike conventional LTE, NB-IoT uses much less power and bandwidth making it suitable for many IoT applications that only need to send small amounts of data at infrequent intervals. It also enables deep indoor coverage and the low power consumption prolongs device battery life to up to 10 years meaning devices can remain in the field with minimal or no maintenance costs.

3GPP has designed LTE to meet these demands, enabling low power, wide area IoT applications to run on licensed spectrum. Proponents of using licensed spectrum, as opposed to unlicensed spectrum as used by other LPWAN solutions such as LoRa, Ingenu and Sigfox, argue that it provides the capacity, network reliability and security enabled by commercial mobile networks.

During the trial, Nokia implemented NB-IoT technology to communicate information on temperature, humidity and air pressure over Sonera's commercial 4G network in the Finnish capital, Helsinki. The companies also connected a roaming device over the commercial network using NB-IoT technology.

This world's first demonstration shows how NB-IoT technology will allow companies to track their mobile assets - for example large maintenance firms such as electricians or plumbers with fleets of vehicles or healthcare providers tracking the status of patients outside of a hospital.

The network used Nokia base station technology operating in the 800 MHz frequency band to maximize coverage and connect to devices in harder to reach locations. The trial saw speeds of up to 200 kbps, showing how the technology can meet the demands of a growing number of devices requiring short burst of network connectivity to transmit small amounts of data and enable the growth of the programmable world.

Sonera CTO Jari Collin said: "In Finland, we have a long tradition of developing and applying new technologies. The trial shows how the use of today's mobile technology will fuel the continued growth of the IoT ecosystem to transform every aspect of our customers' business and personal lives."

Adolfo Masini, head of IoT connectivity at Nokia, said: "Support for the programmable world, in which billions of people, devices and things are connected via high-capacity networks, is the cornerstone of Nokia's strategy. Our strengths in networks, cloud, applications, analytics and security, and our 5G leadership, make Nokia the most qualified to deliver the full potential of IoT.

“Nokia is constantly developing innovative technologies that allow our customers to evolve their offerings. This trial will lay the foundation for an IoT ecosystem in Finland, and allow Sonera to exploit the massive opportunities that it brings."
