Following the 2011 Great East Japan Earthquake, the Japanese government has mandated that 100 million buildings and households be fitted with smart meters by 2020. The key requirements from gas meters were (a) shut down the gas supply remotely in case of an earthquake, (b) operate on batteries for more than 10 years, and (c) use cellular connectivity due to coverage and schedule constraints. The challenge was to develop a solution that could listen to the cellular network continuously to get ‘shut down’ commands in real time, however with power consumption low enough to enable more than 10 years of battery powered operation in the field.

By solving this huge technical challenge while no one else could, and complying with the quality and reliability required, Altair’s Cat-M and NB-IoT chipsets are now deployed in all of Japan’s cellular-connected gas meters.
