Cobham Wireless industry-standard validation
system adds LTE-LAA support for 3GPP Release 13
Cobham Wireless, a global leader in the provision of advanced
wireless coverage and mobile communication systems, has announced
that the industry-standard TM500 network test family can now
validate all the main features of LTE-Advanced (LTE-A) up to and
including Release 12 of the Third Generation Partnership Project
(3GPP) specification. The system has also added support for carrier
aggregation with unlicensed frequency bands as used for LTE Licence
Assisted Access (LAA), a major feature of 3GPP Release 13.
Network operators and infrastructure vendors rely on the timely
availability of support for new 3GPP features to allow them to
validate this functionality on their networks ahead of its
availability on real mobile devices. The addition of these new
features reaffirms the TM500 network test family's reputation for
staying ahead of the LTE-A roadmap, providing advanced network
validation capability as soon as it is needed.
The Release 12 feature line-up includes LTE TDD-FDD carrier
aggregation and 256 QAM, which were both announced last year. The
TM500 also now supports carrier aggregation with unlicensed
spectrum in the 5 GHz WLAN band, as used by LTE Unlicensed (LTE-U)
and LTE-LAA. This increases the available bandwidth and gives the
user the benefit of higher 4G LTE data rates.
"The TM500 network test family maintains its leading position in
LTE-A network validation by continuing to add new features ahead of
market need," said Nicola Logli, senior product manager at Cobham
Wireless. "Network operators are keen for their subscribers to
experience the better 4G service promised by features such as LAA
as soon as possible, and we are providing the validation tools that
will accelerate that process."
More about LTE-U and LTE-LAA
LTE-LAA is a technology for carrier aggregation of LTE with a
secondary cell in the unlicensed band, normally the 5 GHz band that
is already used by WLAN. In order to be able to coexist with WLAN
devices in the same band without causing contention issues, LTE-LAA
uses a protocol known as listen-before-talk (LBT), which is
mandatory in Europe. LTE-U is a similar technology that is already
being used in SE Asia, without the use of LBT.
