Tester is ready for LTE basestations

The Sorbas LTE Test-UE (user equipment) enables basestation developers to test their designs at an early design stage in which the 3GPP-LTE standard is not finalised yet

Signalion has acquired processor technology and knowhow from Dresden Silicon to enable its Test-UE solution for 3GPP LTE (Long Term Evolution) wireless infrastructure testing. Signalion's Sorbas platform is billed as the first test solution for LTE basestations. The Sorbas LTE Test-UE (user equipment) enables basestation developers to test their designs at an early design stage in which the 3GPP-LTE standard is not finalised yet.

One key feature of this test solution is the ability to simulate the behaviour of multiple independent users with a single test system.

Such multiple-UE functionality is needed for very important load and stress tests of wireless infrastructure for 3GPP-LTE.

By enabling scalable, efficient, and flexible signal processing solutions, Dresden Silicon's technology will further strengthen Signalion's ability to support highly complex multiple-UE test scenarios with the Sorbas test-UE solution.

'LTE test systems with multi-UE functionality pose new challenges on scalability and reliability'.

'Our flexible multiprocessor technology, along with the team's solid know-how, gives Signalion exclusive access to a unique methodology for the design of compute-intense software and systems', says Patrick Herhold, CEO of Dresden Silicon.

'Beside traditional functional tests, load and stress tests are very important for the basestation development'.

'The requirements set by the 3GPP-LTE standard on the respective test solutions call for new approaches to the flexible partitioning and sharing of the processing load between multiple processors'.

'The acquisition of Dresden Silicon's multiprocessor technology by Signalion enables a uniquely flexible and cost efficient multi-UE functionality for our basestation test products', says Tim Hentschel, CEO of Signalion.

Both Signalion and Dresden Silicon are located in Dresden, a city that uniquely combines an 800-year historic, baroque background with the pulsing high-tech multi-billion-Euro semiconductor businesses that have turned the region into Europe's number one silicon site.
