IoT

Exynos i S111
NB-IoT solution to make connection go further.
More connections make more changes. The Samsung Exynos i S111 is an LTE modem integrated NB-IoT solution that delivers a reliable wide range communication with ultimate power efficiency for lower data rate IoT applications. The Exynos i S111 also features Samsung’s advanced algorithms for wider coverage and GNSS for accurate real-time tracking. To satisfy the industry’s needs for security and small footprint, the Exynos i S111 integrates an on-chip security sub-system and a PUF security solution along with diverse components such as CPU, RF IC and SRAM in a single chip.

NB-IoT

Connect to IoT
The Exynos i S111 with an integrated modem supports NB-IoT specifications defined by 3GPP’s Release 14. It offers efficient cellular connectivity with downlink speed of up to 127kbps and uplink speed of up to 158kbps.1) The Exynos i S111 utilizes narrowband or signals over a narrow range of frequencies for massive yet efficient machine-type communication.

Coverage

Goes further.
The Exynos i S111 is designed to connect things that are located in remote areas. To connect in these areas that are located far from the wireless communication base station, the Exynos i S111 utilizes low frequency bands which have excellent performance in terms of coverage. This allows small-sized data to be sent or received reliably over a long range with greater power efficiency. Furthermore, the Exynos i S111 with advanced algorithm offers higher link budget which means higher expected received signal to noise ratio resulting in wider coverage.

Power efficiency

Forget battery life.
With NB-IoT, a battery life of more than 10 years can be supported for a wide range of use cases.2) The Exynos i S111 is also designed to operate with extremely low power consumption. With dynamic frequency scaling for CPU and interface, the Exynos i S111 features PSM (Power Saving Mode) that allows user equipment notify its indefinite dormant state to the network and eDRX (extended Discontinuous Reception) that enables user equipment to sleep without
regular network check-in for up to 40 minutes.

Location

Tracking just
got accurate
The Exynos i S111 utilizes two different positioning technologies for accurate user equipment tracking in real-time. The Exynos i S111 integrates Global Navigation Satellite System (GNSS) that supports GPS, Galileo, GLONASS, and BeiDou. The Exynos i S111 also supports Observed Time Difference of Arrival (OTDOA) that utilizes positioning reference signals transmitted in the downlink to enhance positioning information. This enables diverse tracking applications for connected things such as bike sharing, kids tracker​ and livestock monitoring services.

All-in-one solution

Packed with versatility
Samsung’s advanced design technology packs diverse components for the all-in-one NB-IoT solution in a single chip. It features Cortex®-M7 core as a main CPU with a static RAM, a modem and an RF IC for connectivity, and a GNSS for location services. With coin-sized small footprint, the Exynos i S111 enables tiny IoT module design for user equipment.

Security

Secure things for reliable IoT
As IoT devices provide convenient services based on private information, it is becoming highly potential target for cyber-attacks or security threats. The Exynos i S111 features on-chip security sub-system and PUF (Physically Unclonable Functions) to support Isolated Execution Environment (IEE) powered by dedicated processing unit. PUF security feature generates and utilizes a unique key, or silicon fingerprint, for safer certification when an IoT module communicates with a server.
