Aeroflex And 7Layers Collaborate On LTE Device Verification

untitled

Aeroflex Incorporated, a wholly owned subsidiary of Aeroflex Holding Corp., and 7Layers, an international group of engineering & test centers, have joined forces to provide the LTE testing market with a cost-effective test system that assesses the interworking of LTE-capable terminals or chipsets with LTE networks and the Universal Integrated Circuit Card (UICC).

Based on 7Layers' InterLab Test Solution LTE-USIM/USAT in combination with the Aeroflex 7100 Digital Radio Test Set, the new system is a cost-effective and reliable test set-up that is ideally suited for both conformance and R&D test purposes.

The Aeroflex 7100 Digital Radio Test Set is an LTE network emulator that provides all the tools required during the design, development and test stages of UE chipsets and LTE-capable terminals meeting 3GPP Rel-8 & 9 standards.

The InterLab Test Solution LTE-USIM/ USAT from 7Layers verifies the interworking of LTE-capable devices with LTE networks for TDD and FDD and the respective USIM and USAT applications on the UICC. It covers 3GPP TS 31.121 and TS 31.124 Rel-8/9 test specifications and is a listed test platform at GCF and PTCRB.

In cooperation with Aeroflex, 7Layers has successfully integrated the Aeroflex 7100 with its InterLab Test Solution LTE-USIM/USAT for LTE-only test cases, with further extensions of the test case packages in progress. This will enable the user to migrate UICC conformance testing from expensive test systems to a cost-effective solution that allows UICC testing to be performed during R&D. Thanks to a straightforward graphical user interface, all the test equipment involved is simple to control. The high level of automation provides highly reproducible results that are aligned to meet 3GPP standards, which is essential in order to achieve GCF and PTCRB certification.

"These test cases require the joint operation of several test systems and, due to their complexity, are prone to error when handled manually", explains Magdy Ahmed, product manager at 7Layers. "However, development and conformance test procedures have to be efficient and must provide accurate and exactly reproducible results, which can only be achieved by using dependable, straightforward test set-ups."

"7Layers has had years of experience with USIM and USAT testing in their own laboratories, before developing their new InterLab Test Solution LTE-USIM/ USAT", explains Michael Thorpe, Product Line Manager at Aeroflex. "Based on this experience, 7Layers has developed an extremely easy to handle, reliable solution. It is very well suited for network independent tests as well as for test cases that require the joint operation with our Aeroflex 7100 LTE network emulator. We feel certain that this solution will not only catch the interest of conformance test laboratories but also of R&D labs all over the world."
