Keysight Combines 5G and
Global Navigation Satellite System Technology to
Accelerate Implementation of Location Based Services
(LBS)
October 31, 2022
Keysight Technologies, Inc.
announced that it is first to gain Global
Certification Forum (GCF) validation of a 5G
location based services (LBS) Assisted Galileo
(A-Galileo) test case by combining 5G new radio (NR)
and global navigation satellite system (GNSS)
technology.
This industry achievement will
accelerate the implementation of LBS in smartphones
by enabling mobile phone vendors to verify that
designs comply to the latest 3GPP specifications
that support accurate location positioning in a wide
range of sectors, including healthcare, road and
aerial transportation, emergency and rescue
services, public safety, and homeland security.
Highly precise positioning services also enable
mobile operators to deliver personalized services
supporting entertainment, hospitality, and retail
applications.
“The GCF validation of the
first 5G LBS test case demonstrates Keysight’s
commitment to supporting rapid development of
technologies that enhance 5G NR deployment,
benefiting consumers, enterprises, and government
organizations,” said Muthu Kumaran, General Manager
at Keysight Technologies. “Keysight brings holistic
test capabilities to a connected ecosystem of
chipset and device vendors that relies on device
test platforms with continuous and comprehensive
test case support, meeting the evolving requirements
of GCF and other reference certification bodies.”
LBS leverages different
technologies, including global positioning system
(GPS), GNSS, BeiDou, Galileo, beamforming, and
round-trip time (RTT) to geographically locate a
user. LBS test cases allow users to verify
sensitivity, accuracy, and dynamic range in mobile
phones that leverage satellite constellations such
as GPS, Galileo, GLONASS, and BeiDou to identify
precise geographic location.
The GCF conformance agreement
group (CAG) meeting #72, held on October 21,
confirmed the validation of the first 5G LBS
A-Galileo test case, which was supported by
Keysight’s S8705A RF/RRM DVT and Conformance
Toolset. The toolset provides access to a wide range
of radio frequency, radio resource management (RRM),
and development validation test (DVT) test cases
used to verify 5G NR designs in both non-standalone
(NSA) and standalone (SA) deployment modes.
The S8705A toolset used the
E7515B UXM 5G Wireless Test Platform, a compact
signaling test platform with multiformat stack
support, rich processing power, and abundant RF
resources for emulating various mobility scenarios
in a 5G network as well as a recommended GNSS
emulator to deliver the LBS test case. At the CAG
#72 meeting, it was also confirmed that Keysight
continues to support a leading number of GCF
validated conformance test cases for 5G RF, RRM, and
protocol testing.
