Samsung today announced its new narrowband (NB) Internet-of-Things (IoT) solution, Exynos i S111.
The solution offers 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. It 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.
To cover long distances with high reliability, as a standard, NB-IoT adopts a data retransmission mechanism that continuously transmits data until a successful transfer, or up to a set number of retransmits. With a high number of these retransmit sessions, the S111 is able to cover the distance of 10-kilometers (km) or more.
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.
Following the launch of the company's first IoT solution, Exynos i T200, in 2017, Samsung plans to continue expanding the 'Exynos i' lineup with offerings specially tailored for narrowband networks.
