Samsung Electronics announced a new chip for NB-IoT devices, the Exynos i S111. The company said the chip supports wide coverage, low-power operation, accurate location feedback and strong security, making it suitable for real-time tracking applications such as safety wearables or smart meters. The platform includes a modem, processor, memory and Global Navigation Satellite System (GNSS), all in a single-chip design.
The i S111 is able to cover distances of 10km or more and can transmit data at 127 Kbps for downlink and 158 Kbps uplink. It can operate in standalone, in-band and guard-band deployments. For long standby periods, the S111 utilizes power saving mode and expanded discontinuous reception, which keeps the device dormant for periods up to 10 years, depending on application and use-cases. In addition to GNSS, it supports Observed Time Difference of Arrival, a positioning technique using cellular towers.
The launch follows Samsung's first IoT chip, the Exynos i T200, in 2017. Samsung said it plans to continue expanding the ‘Exynos i‘ lineup with offerings especially tailored for narrowband networks.
