- Joint solution developed to assess the transmitter / receiver
performance of devices supporting narrowband non-terrestrial
networks under over-the-air conditions
- Provides a key enabler to accelerate the mobile ecosystem’s
rapid deployment ambitions for non-terrestrial networks
Keysight Technologies, Inc. (NYSE: KEYS) and ETS-Lindgren
announce an industry-first over-the-air (OTA) test solution for
devices supporting the narrowband non-terrestrial networks (NB-NTN)
technology.
Non-terrestrial networks (NTN), a feature of 3GPP Release 17
(Rel-17), enables cellular communications to be delivered by
satellite, providing secure, reliable, and high bandwidth coverage
to isolated locations globally. The initial technology enabled by
NTN is narrowband internet of things (NB-IoT), which enables many
new use cases, including asset tracking, remote monitoring, and
emergency services. This enables mobile network operators to
provide coverage to a wider geographical area and a larger number
of subscribers.
Working in close partnership, Keysight and ETS-Lindgren
developed a joint OTA test solution for measuring and validating
the transmitter / receiver performance of devices supporting
NB-NTN. These tests allow device manufacturers to assess real-life
performance to ensure they meet consumer expectations and the
requirements of network operators and regulators. The solution will
also support the forthcoming CTIA OTA test requirements for NTN
devices.
The combined solution comprises Keysight’s UXM E7515B NTN
software and ETS-Lindgren’s OTA test chambers and EMQuest Antenna
Measurement Software. The Keysight NTN software runs on the
Keysight E7515x family of UXM 5G Wireless Test Platforms and
emulates both terrestrial and satellite networks, including
satellites in low, mid, or geo-stationary/synchronous orbits to
test the effects of Doppler shifts. The built-in channel emulation
capabilities of the UXM 5G also allow the performance of devices to
be assessed under real-world channel fading conditions in a lab
environment. Along with ETS-Lindgren’s OTA test chambers and
EMQuest Antenna Measurement Software, the fully integrated solution
allows the transmitter and receiver performance of NTN devices to
be assessed, including measurements such as Total Radiated Power
(TRP) and Total Isotropic Sensitivity (TIS).
Keysight’s portfolio of NTN test solutions also supports testing
of 5G New Radio and unmodified LTE devices over NTN connections,
which are anticipated to be supported by NTN.
James Young, Director of Wireless Solutions, ETS-Lindgren,
said: “NTN and direct-to-device satellite technologies are
generating significant interest as designers consider the use cases
and applications that could be built around this new link method.
The buzz around NTN, and the need to answer questions about device
performance and capabilities, pushed ETS-Lindgren to prioritize
building this test capability for our OTA system users. The
cooperative approach with the Keysight UXM 5G Emulation Solution
team helped accelerate the development of this important OTA test
and allowed quick integration within EMQuest.”
Chih Kai Wu, Wireless Solution Director, Keysight Wireless
Test Group, said: “Keysight is delighted to partner with
ETS-Lindgren to deliver the industry’s first NB-NTN OTA test
solution. This partnership demonstrates the technology leadership
of both companies and enables the mobile ecosystem to accelerate
the deployment of NTN networks, devices, and services.”
