Singaporean operator M1 and Nokia have conducted a ‘live’ Narrowband Internet of Things (NB-IoT) demo. Carried out at M1’s advanced networks lab, the demo simulated an environmental monitoring telemetry service. It featured a remote room temperature and humidity sensor application, whereby data from the sensor is collected and shared via NB-IoT connectivity. This showcased how NB-IoT could be used to connect the millions of sensors expected to be installed nationwide as part of Singapore’s journey to become a Smart Nation, M1 said.
