Nokia conducted a trial using NB-IoT (Narrowband Internet of Things) technology on Finnish operator Sonera's commercial 4G network. The trial used Nokia base stations operating in the 800 Mhz band to maximize coverage.
The NB-IoT technology was used to communicate information on temperature, humidity and air pressure over Sonera's 4G network in 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.
NB-IoT is a 3GPP Rel. 13 radio access technology designed especially for enabling cellular connectivity to Internet of Things devices. Nokia said NB-IoT will co-exist with operators' existing networks to benefit from mobile security and privacy features.
