Aeroflex TM500 TD-LTE multi-UE

Aeroflex has announced the TM500 TD-LTE multi-UE, adding multiple handset (multi-UE) testing capabilities to its test mobile range supporting TD-LTE infrastructure development.

The device enables TD-LTE infrastructure equipment vendors to test the performance of their TD-LTE base stations (e-NodeBs) under loaded conditions.

The test mobile replicates multiple TD-LTE handsets in a single test mobile, simplifying complex tasks such as functional network testing with multi-UEs and performance measurement of resource scheduling algorithms. The device can be used to repeatedly generate controlled test scenarios involving a user-defined number of UEs.

The unit replicates programmable and fully configurable UEs that are representative of TD-LTE handsets enabling them to measure loaded eNode-B performance before real handsets become available. It provides a controlled, repeatable and deterministic test environment to operate multiple UEs on the same test platform with a single point of control.

In addition to functional multi-UE testing, the use of the same test platform enables specific tests that require UE coordination and for which it is not practicable to use independent handsets.

Such tests include contention between UEs attempting to access the network simultaneously and the ability to check a network’s response if multiple UEs behave unexpectedly or abnormally together.
