Verify the Actual Performance of a Mobile Device with
Keysight’s Future-Proof Integrated Test Solution
LTE delivers an improved end-user experience with faster data rates compared to
WCDMA HSPA+. Faster data rates lead to more complex mobile devices that require
more extensive testing prior to market introduction. As a result many mobile operators
and device manufacturers conduct performance testing based on channel emulators
to develop and launch products that meet end-users’ increasing expectations.
Propsim radio channel emulators from Keysight Technologies accurately simulate the
characteristics of real-world radio channel conditions within a laboratory environment.

MIMO (Multiple Input, Multiple Output) – a key feature in LTE and LTE Advanced – de-
livers higher bandwidth and data rate services to end users. Mobile devices with MIMO
technology - where both the base station and the device are equipped with multiple
transmit and receive antennas - are highly complex and difficult to test. Over-the-Air
(OTA) testing effectively overcomes this complexity by incorporating the device antenna
performance. Perform tests under similar conditions to how the device operates in the
real world – in other words – without any cables connected to it.
Use MIMO OTA performance testing to evaluate the end user’s experience accessing
data services on a mobile device. All critical parts of the mobile device design – including
the antennas, RF front end, baseband processing – are thoroughly and simultaneously
tested in real-life conditions. Poorly designed devices significantly increase network load
and optimization issues, so major mobile operators mandate specific test requirements
to ensure correct device performance.
Complex devices require efficient, precise and non-intrusive testing that emulates real-
world field conditions across a large sample of devices and over various manufacturing
runs. MIMO OTA device testing accurately emulates the end-user’s experience when
accessing applications, downloading video in ‘landscape mode’ or browsing in ‘portrait
mode’.
