Keysight Technologies
LTE and LTE-Advanced Solutions
Accelerate Wireless Design and Test
With lexible, high-performance platforms

Today LTE or Long Term Evolution is well on its way to becoming the first single global
standard for cellular communications. Providing the delivery of the next generation of
mobile broadband, LTE and now LTE-Advanced continues to provide many challenges
to the engineers developing and delivering products that work to the standards.

Keysight Technologies, Inc. is a leader in wireless test, focused on the highest-
performance design and test of wireless devices and networks, with application-
focused platforms optimized for existing and emerging standards. Integrated
platforms feature the industry's broadest range of both hardware (benchtop and
modular instruments) and software building blocks, and span the entire development
cycle--from early design simulation to manufacturing. Leveraging Keysight
unparalleled wireless measurement and application expertise, these building blocks
help you anticipate and respond to emerging RF challenges in wireless devices
and networks with the high performance and flexibility needed to provide the right
solution for any situation.

Keysight is a member of 3GPP and an active contributor to the development of next-
generation specifications. Keysight product plans are based on the knowledge and
insight gained from this participation to ensure our suite of design and test solutions
keep pace with evolving technology. Our robust knowledge library of application
notes, webcasts, videos, CDs and now with our 2nd Edition of the LTE book is
designed to help you interpret, clarify and test to an evolving LTE and LTE-Advanced
standard. Accelerate wireless design and test.
Keeping Pace with Technology

LTE-Advanced
Moving Forward to Increase Capacity
LTE-Advanced is the evolved version of LTE that is being developed by 3GPP
to meet or exceed the requirements of the International Telecommunication
Union (ITU) for a true fourth generation radio-communication standard known
as IMT-Advanced. LTE-Advanced is defined in Release 10 and all the follow on
releases including Release 12. LTE-Advanced is focused on higher capacity with
increased peak data, higher spectral efficiency, increased number of simultaneously
active subscribers and improved performance at cell edges.

TD-LTE
Evolving LTE Speciications -- from FDD-LTE to TD-LTE
Following the integration of the Chinese TD-SCDMA standard, based on Time
Division Duplex (TDD), into the 3GPP specifications for LTE, chipset and device
designers are now working to include TDD capability. Now known as TD-LTE, the
standard caters to the asymmetric needs of mobile data usage, and allows carriers
to make use of the unpaired spectrum that many of them already own. Keysight was
the first to provide solutions for testing this new technology and currently offers
TD-LTE solutions from design simulation to signal generation and analysis.

MIMO
New Multiple Input Multiple Output Transmission Scenarios
The specified RF environment for LTE includes not only basic signal transmission
and reception, but also multiple input multiple output (MIMO) scenarios with up to
four separate transmitters and receivers. For module and component test, complex
frame-based test signals are passed through the device under test and measured
using vector signal analysis to determine EVM and CCDF. Keysight offers a complete
set of design and test solutions for MIMO technology--from design simulation to
signal generation and analysis through manufacturing and deployment.

Heterogeneous Networks
Adding to the LTE Architecture with Small Cells
Another way to expand capacity is with small cells. Small cells offer flexibility, bring
down the costs of installation and lower power usage but they also bring along
test challenges such as interference design and test and the need for lower cost
manufacturing. Building on our demonstrated history of leadership and proven track
record delivering base-station test equipment, Keysight offers small cell design and
test solutions to help you meet your design and production-cost goals.
