Situation: Following the 2011 Great East Japan Earthquake, the Japanese government mandated that 100 million buildings and households be fitted with smart meters by 2020.

Challenges: To develop a solution that enables continuous network availability and remote access, while allowing smart gas meters to maintain over 10 years of battery life in the field.

Solution: Meter design based on Sony’s Altair highly integrated LTE-M/NB-IoT ALT1250 chipset.

Results: The Sony Altair chipsets now provide continuous LTE-M connectivity for all cellular-connected gas meters in Japan.
