The new NB-IoT solution offers extremely wide coverage, low-power operation, accurate location feedback and strong security, optimized for today’s real-time tracking applications such as safety wearables or smart meters. The solution includes a modem, processor, memory and Global Navigation Satellite System (GNSS) into a single chip design to enhance efficiency and flexibility for connected device manufacturers.
“IoT will be able to evolve to offer new features beyond the conventional household space with IoT-dedicated solutions that present a broad range of opportunities,” said Ben Hur, vice president of System LSI marketing at Samsung Electronics. “Exynos i S111’s highly secure and efficient communication capabilities will bring more exciting NB-IoT applications to life.”
Exynos i S111 incorporates a modem capable of LTE Rel. 14 support that can transmit data at 127-kilobits-per-second (kbps) for downlink and 158kbps uplink, and can operate in standalone, in-band and guard-band deployments.
For long standby periods, the S111 utilizes power saving mode (PSM) and expanded discontinuous reception (eDRX), which keeps the device dormant for long periods of time of 10 years and more, depending on application and use-cases. Exynos i S111 also has an integrated Global Navigation Satellite System (GNSS) and supports Observed Time Difference of Arrival (OTDOA), a positioning technique using cellular towers, for highly accurate and seamless real-time tracking.
Transmitted data are kept secure and private with the S111, as the solution utilizes a separate Security Sub-System (SSS) hardware block along with a Physical Unclonable Function (PUF) that creates a unique identity for each chipset.
