LTE test services and products at 7 layers
At last ultramodern LTE devices are beginning to enter the
market, finally making the long promised mobile web
a reality! Faster, more bandwidth-intensive services are
in the process of being launched. Now a major effort is
necessary to make network infrastructures
and mobile devices fit for these new challenges. Long Term Evolution (LTE) in combination with System
Architecture Evolution (SAE) is the next significant step
in moving
mobile communications towards the all-IP environment.
Such fundamental changes need to be accompanied by careful
technology development and thorough testing. Essential
prerequisites to ensure new LTE services and LTE products
work together perfectly in order to guarantee user satisfaction.
LTE test capabilities at 7 layers
▪
RF testing for LTE
▪ Protocol testing for LTE
▪ LTE-USIM testing ( also on offer as
InterLab Test Solution LTE USIM ! )
▪ OTA test services for LTE
The LTE test services are provided by the 7 layers laboratories
in North
America, Europe and Asia.
LTE experience of 7 layers
7 layers already has gained broad experience
of the complexities and necessities of LTE testing:
We are the first
company to have succeeded in
validating LTE test cases.
We have integrated various
LTE radio communications testers for network
simulation into
the InterLab System ( e.g.
Rohde & Schwarz CMW500 and AWT800 from Innowireless).
We have developed the highly automated, user friendly
InterLab
Test Solution LTE-USIM.
LTE Test Case Validation
7 layers is the first company world-wide that has succeeded in
validating LTE test cases. 7 layers has already verified and validated
LTE protocol test cases against a radio communications tester for network
simulation. These test cases have been approved by GCF
and PTCRB. Thanks to these activities certification of
leading-edge LTE devices
has reached a further important milestone!
InterLab Software System – now fit for LTE!
InterLab Software System
▪ organizes test and verification processes
▪ provides an information data base
▪ generates test plans automatically
▪ automates test execution and reporting.
▪ supports version control processes
▪ facilitates result analysis
To make the InterLab
Software System fit for LTE,
the InterLab information
system has been extended to include the LTE scope.
It features elements such as LTE test cases, LTE specification, test
specifications, certification requirements etc.
This means complex LTE test plans can be generated in minutes!
The InterLab test
engines enhance the capabilities of LTE test equipment with
several automation functionalities: The testers as well as the device under test can be
fully automated. InterLab test engines have been developed
for both the Rohde & Schwarz CMW500 and the AWT800 from Innowireless.
The InterLab report generator helps provide LTE test reports for R&D requirements
and for the upcoming LTE certification requirements.
LTE - USIM Test Solution based on InterLab -
now available!
7 layers has developed a one box test solution for LTE-USIM tests.
The InterLab
Test Solution LTE-USIM verifies
the correct interworking between
the LTE device and the USIM application as well as the interaction with
the E-UTRA/ EPC network. It features a communication interface between the
LTE device and the USIM application, using the Rohde & Schwarz CMW500
for network simulation. It can also be easily adapted
to other
customer-chosen protocol test systems, available on the market today.
Comprising all test sequences according to 3GPP TS
31.121 Rel-8, it is an ideal platform throughout all phases of LTE
device development and certification. It eases the test processes and
speeds up the product launch of LTE User Equipment. Users benefit from
its ease of use and its outstanding automation capabilities for combined
LTE-USIM tests, network-independent SIM interface tests or for the
automated operation of an LTE network simulator.
