Samsung Exynos i S111 is all-in-one chip with modem, processor, memory and GNSS functions

Aug 23, 2018, 5:45 am

Samsung Exynos i S111, Samsung Electronics’ new NB-IoT (narrowband Internet of Things) solution, has been unveiled today in a press release in South Korea, with the plans of expanding the ‘Exynos i’ series that was first launched successfully in 2017.

This new solution combines a modem, processor, memory and Global Navigation Satellite System (GNSS) into a single chip design to provide enhanced efficiency and productivity. It offers quite a wide coverage, low-power operation, strong security and precise location. The new NB-IoT solution can work well with recent tracking applications that use real-time including safety wearables or smart meters.

IoT solutions present a broad range of opportunities and that through these solutions IoT will be able to evolve to offer new features beyond the conventional household space. – Ben Hur, vice president of System LSI marketing at Samsung Electronics

He assures that Samsung Exynos i S111 is highly capable of providing security and efficient communication and can enhance even more exciting NB-IoT applications.

While radio connectivity systems like Bluetooth and ZigBee offers only short-range coverage, NB-IoT is suited for applications requiring low-power communication and wide-range coverage for small-sized data. NB-IoT works with a data retransmission mechanism that transmits data continuously until one or more successful transfer(s). The Exynos i S111 accommodates a modem with support capability of LTE Rel. 14 which helps data transmission at the speed of 127-kilobits-per-second (kbps) for downlink and 158kbps uplink. It can successfully cover more than 10km distance for even a large number of retransmitting sessions. It has the ability to operate in standalone, in-band and guard-band deployments.

The Samsung Exynos i S111 utilizes power saving mode (PSM) and expanded discontinuous reception (eDRX) that can keep the device dormant for long standby periods up to 10 years and more. The Global Navigation Satellite System (GNSS) and Observed Time Difference of Arrival (OTDOA) techniques can provide highly accurate and fluid real-time tracking. Moreover, the S111 utilizes a separate Security Sub-System (SSS) hardware block along with a Physical Unclonable Function (PUF) which designs an exclusive identity for each chipset and thus, keeps transmitted data secure and private.
