Samsung Electronics has announced its new narrowband (NB) Internet of Things (IoT) solution, Exynos i S111.
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 vendor said.
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, Samsung said.
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 127kbps 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. Exynos i S111 also supports observed time difference of arrival (OTDOA), a positioning technique using cellular towers, for highly accurate and seamless real-time tracking.
