Automotive on-glass
antenna R&D framwork
By completing its anechoic chambers
in Europe, AGC has established a
framework for accelerating the research
and development of antennas to meet
demand for “connected” cars in the
age of IoT and supporting automobile
development by its customers on a global
scale. On March 15, 2019, AGC inaugurated
anechoic chambers constructed in
Gosselies (Belgium) for the development
of automotive on-glass antennas. With the
completion of this R&D facility, AGC has
established a tri-polar R&D framework for
automotive on-glass antennas in Japan,
the United States and Europe for the first*
time in the glass industry.
In a future mobility society, cars will be
equipped with devices such as cameras,
LiDARs and sensors. Cars will need to be
both connected to each other and have
communicative functionality that delivers
V2X, connecting cars to all other things.
In these circumstances, automotive glass
is playing an increasingly important role
as an antenna/gateway for RF.

Commercial deployment
of 5G NR
Xilinx, Inc., and Samsung Electronics
Co., Ltd., have expanded their collaborative
efforts resulting in the first 5G New
Radio (NR) commercial deployment in
South Korea, which will be followed by
additional countries globally in 2019 and
beyond.
Xilinx and Samsung have been
working together to develop and deploy
multiple 5G Massive Multiple-input,
Multiple-output (mMIMO) and millimeter
wave (mmWave) systems using the
Xilinx® UltraScale+™ platform. Additionally,
Samsung is collaborating with Xilinx
on its forthcoming Versal® adaptable
compute acceleration platform (ACAP)
products to deliver state-of-the-art 5G
systems. The goal is to address a multi
fold increase in compute density requirements
in next-generation 5G mMIMO
systems while enabling the use of
machine learning algorithms to maximize
the benefits of beamforming gains to
further boost capacity and performance.

Optical frequency comb claims
to be smallest
Although chip-scale versions of optical
frequency combs using microresonators
were first demonstrated
in 2007, a fully integrated
form has been hindered
by high material losses
and complex excitation
mechanisms, until now.
Research teams led
by Tobias J. Kippenberg
at EPFL and Michael
L. Gorodetsky at the
Russian Quantum Center
have now built an integrated soliton
microcomb operating at a repetition rate
of 88 GHz using a chip-scale indium
phosphide laser diode and the silicon
nitride (Si3N4) microresonator. At only
1 cm3 in size, the device is the smallest
of its kind to-date. The microresonator
is fabricated using a patented photonic
Damascene reflow process that delivers
very low losses in integrated photonics.
These ultra-low loss waveguides bridge
the gap between the chip-based laser
diode and the power levels required to
excite the dissipative Kerr soliton states,
which underly the generation
of optical frequency
combs.
The method uses
commercially available
chip-based indium phosphide
lasers as opposed
to conventional bulk laser
modules. The rported
work cites that a small
portion of the laser light is

reflected back to the laser due to intrinsic
scattering from the microresonator.
This direct feedback helps to both stabilize
the laser and generate the soliton
comb – showing that both resonator and
laser can be integrated on a single chip
and offering a marked improvement over
past technology. The whole system can
fit in a volume of less than 1 cm3 and
can be controlled electrically.

Telit shortens path to IoT
monetization
An innovative software suite that
enables solutions for a new generation
of the company’s cellular LPWA IoT
modules, OneEdge features integrated,
secure, easy-to-use tools – dramatically
simplifying design, deployment
and management of IoT products and
systems.
A big step towards a 5G world,
OneEdge solves long-standing challenges
related to integration, scalability,
management and costs that architects
and their enterprise customers face as
they implement IoT to transform their
businesses. The offering is designed
to accelerate systems to market in an
industry that is expected to scale to
three million-plus new cellular connections
per day by 20231.
OneEdge provides faster implementation
and shortens time to value by
providing:
• Zero touch on-boarding – making
products operate automatically «out
of the box,» lowering costs of initial
deployment, making it simpler, and
more secure.
• Device management – managing
data and cellular systems needed to
connect devices to the Cloud or Enterprise
ensuring each device has the
most up to date firmware and application
software.
• Security built-in at point of manufacture
– hardening products to attacks,
leveraging layers of security from the
module through cellular transport to
the delivery of information.
• SIM-less cellular subscription management
– integrating directly into the
LPWA module, simWISE is a subscriber
identification solution that provides
an unparalleled reduction in cost and
complexity for IoT deployments.
• Edge programmability – providing tools
to normalize data and define the logic
and behavior of devices.
• Simplified enterprise integration
