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 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.

"IoT will be able to evolve to offer new features beyond the
conventional household space with IoT-dedicated solutions that present a
broad range of opportunities," said Ben Hur, vice president of System
LSI marketing at Samsung Electronics. "Exynos i S111's highly secure and
efficient communication capabilities will bring more exciting NB-IoT
applications to life."

As IoT grows to be a part of our everyday lives, some connected devices
share useful information instantly in high volumes, but some transmit
data in small nuggets over a long period of time. Popular radio
connectivity systems such as Bluetooth and ZigBee are suitable for
short-range scenarios within confined spaces such as in the home or a
building, and broadband communications are commonly used for mobile
devices that demand high data rates. On the other hand, NB-IoT supports
applications that require reliable low-power communication and
wide-range coverage for small-sized data.

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

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 successful 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.
