Nordic Semiconductor, a world chief in low energy wi-fi connectivity options, has introduced the supply of nuSIM for its nRF91 Sequence of mobile IoT modules. This software program SIM answer eliminates the necessity for a bodily SIM card and socket, permitting product builders to scale back machine measurement, simplify manufacturing, and improve the robustness of their mobile IoT designs.
Open customary and future-proofed
nuSIM is an open customary strategy to built-in SIM (iSIM) the place SIM credentials are encrypted and managed inside a safe, protected space of the machine. By working as a devoted software program element contained in the safe Arm TrustZone of the nRF91 Sequence’ software processor, nuSIM removes all exterior SIM {hardware}, immediately lowering the invoice of supplies (BOM) and saving invaluable board area. That is excellent for mobile IoT units deployed in harsh environments—for instance in water metering or good farming irrigation functions—as eradicating the SIM socket eliminates a typical level of mechanical failure and protects in opposition to corrosion and vibration. The totally digital provisioning course of streamlines the availability chain, permitting SIM profiles to be securely delivered to units throughout manufacturing, simplifying logistics and lowering operational prices.
“Making mobile IoT as easy and accessible as doable is a core mission at Nordic,” says Oyvind Birkenes, EVP Lengthy-Vary at Nordic Semiconductor. “By integrating the nuSIM customary into our nRF9151 and nRF9160 modules, we’re eradicating the bodily barrier to creating ultra-compact, strong, and cost-effective mobile IoT merchandise. Builders can now handle connectivity fully within the digital area, from manufacturing to deployment. This can be a vital step ahead for the business.”
Seamless integration and safe provisioning
Integrating nuSIM on an nRF91 Sequence module is a one-time software program integration course of utilizing Nordic’s highly effective nRF Join SDK (Software program Improvement Equipment) along with the Redtea Cellular nuSIM integration library, the code to combine the nuSIM working system in accordance with the open nuSIM specification. As soon as the nuSIM integration library is included within the machine firmware, the manufacturing unit provisioning workflow is easy.
After the appliance firmware containing the nuSIM is loaded onto an nRF91 Sequence module, a specialised software program instrument made by Redtea prepares the machine to securely obtain its SIM profile, then the instrument connects to a specific community operator to securely obtain and set up a novel SIM profile onto every machine. The nuSIM implementation on the nRF91 Sequence has been security-evaluated and authorized by the impartial testing institute TÜV Nord in Germany, making certain it meets the very best requirements for safety and reliability.
“nuSIM not solely reduces SIM overhead prices, it additionally consumes much less energy than a standard SIM,” continues Birkenes. “Whereas Nordic’s nRF91 Sequence is already probably the most power-optimised and extremely built-in mobile IoT module collection in the marketplace, nuSIM is one other means we will improve the sphere lifetime of our clients’ finish merchandise that could be anticipated to final years with out battery substitute.”
Accessible now
The nuSIM answer for the nRF91 Sequence is accessible now. The primary cell community operator (MNO) offering business profiles for nuSIM is Deutsche Telekom, one of many world’s main telecommunications corporations. Additional MNOs and companions will likely be introduced later. To entry detailed documentation, software program and the required instruments for growth, Nordic clients and builders can see right here.
