Japanese mobile phone operator NTT DoCoMo has enlisted global wireless machine tech company Telit to help bring low-cost IoT to the Fujisawa Sustainable smart town. The ambitious smart town is a joint public-private venture aiming to hold 1,000 households in an unprecedentedly "advanced technology-based infrastructure".
Telit has produced a SIM card alternative, first of its kind, the ME910C1-J1. It replaces the traditional SIM card and tray with module embedded SIM technology. Featuring Telit's simWISE technology, It can support a maximum data downlink and uplink of 250-375 kbps, depending on whether it is M1 or NB1 mode. It also has power saving mode (PSM) and extended discontinuous reception (eDRX) features which work to significantly extend battery life, further driving down costs associated with frequent battery replacement.

The ME910C1-J1 also has better coverage when compared to other cellular companies of +15dB/+20dB in maximum coupling loss (MCL), ideal for IoT applications underground or deep in buildings. It is also both cheaper to manufacture and deploy than regular SIMs, a key benefit in the highly cost sensitive IoT market.
Of the move, Derick Tsang, Telit APAC region president commented, "The Fujisawa Sustainable Smart Town will show the world not only what the future of smart cities looks like, but also the fundamental role that low-power wide-area (LPWA) wireless technologies will play in enabling that future."
