Bluetest and Spirent Deliver Fast, Accurate and Reliable MIMO Over-The-Air (OTA) Test Solution
SUNNYVALE, Calif. --(Business Wire)--
Communications, the leader in testing wireless networks, services
and devices, announced its collaboration with Bluetest
to deliver an integrated test solution that provides unprecedented
accuracy and reliability for MIMO Over-The-Air (OTA) throughput testing.
Leading North American operators have developed their own MIMO OTA test
plans and are requiring immediate support for evaluating the performance
of this critical technology in next-generation LTE (News - Alert) devices.
Multiple Input and Multiple Output (MIMO), is the use of multiple
antennas (at both the transmitting and receiving end) and is vital to
fully realizing the improved communications promised by LTE and LTE
Advanced. Mobile operators worldwide are upgrading their networks with
MIMO technology to deliver on the demand for higher data rates, greater
coverage areas and lower operational costs. Although standards bodies
are still defining MIMO OTA test standards for the industry, leading
operators are moving ahead and requiring conformance to their MIMO OTA
test plans now.
"Our close partnership with Spirent (News - Alert) was a deliberate move to produce the
most dependable and comprehensive MIMO OTA test system in response to
leading operators' MIMO OTA test requirements," said Kjell Olovsson,
Bluetest CEO. "Spirent's VR5 Channel Emulator integrated with our
Reverberation Test System allows us to create a wider range of reference
environments in the lab and accurately validate LTE data throughput
under challenging MIO conditions."
The performance of MIMO is especially sensitive to the system design in
a wireless device. The many interactions between antennas, case design,
RF modules, chipsets and firmware make a dramatic difference in a
highly-efficient product capable of high data throughput rates. OTA
testing is where these interactions first become apparent and where
designers really start to see the full system performance. The
reverberation chamber provides a dynamic free-space reference
environment upon which wireless channel emulators apply real-world
spatial channel models. This enables the user to precisely characterize
how well a mobile device with MIMO receives signals and operates in an
environment with these real-world spatial properties.
"Being first to apply the reverb chamber to wireless testing, Bluetest
is well recognized as an industry leader in OTA testing methodology,"
said Dave Garrison, Spirent's Senior Director of Wireless Product
Development. "Bluetest's years of experience deliver a higher degree of
accuracy and reliability, and their selection of Spirent's VR5 Channel
Emulator confirms our shared commitment to support the industry's urgent
need to validate MIMO performance on next generation devices."
This MIMO OTA solution integrates Bluetest's RTS60 Reverberation Test
System with Spirent's VR5 Spatial Channel Emulator. The RTS60 provides a
rich environment for fast, easy and realistic performance measurements
on MIMO devices and is backed by Bluetest's years of experience in OTA
reverberation measurement technology. Spirent's
VR5 is an industry leading spatial channel emulator that delivers
unprecedented ease of use for testing MIMO devices and base-stations in
the complex RF environments used in LTE and LTE-Advanced.
