Aeroflex TM500 LTE test mobile with Cat5 support

Thursday, 02 February, 2012 | Supplied by: Cobham AvComm

Aeroflex has announced that their TM500 LTE test mobile can emulate LTE Category 5 (Cat5) user equipment, allowing operators to verify the operation of their networks and equipment vendors to prove the performance of their eNodeB (LTE base stations) at the higher data rates that are enabled by Cat5 handsets and terminals.

The test mobile provides demodulation and decoding of downlink signals transmitted in 4x4 MIMO and transmission of uplink signals modulated using 64QAM, in support of these higher LTE data rates. The addition of Cat5 support allows engineers to verify the signal processing function when testing systems at the higher data rates provided by LTE and its hybrid automatic repeat request (HARQ) mode permits validation of the Cat5 feature prior to integration into the eNodeB.

The test mobile's ′per antenna′ measurement capability allows engineers to validate eNodeB RF functionality with direct cabling, while its ′per RF path′ measurements provide a tool for use over the air during field trials, for studying the use cases that maximise the benefits of the four transmitter topology of 4x4 MIMO. A constellation plot is also available, which provides a rapid scan of the signal quality.

The test mobile can also be used in stress test cases at an early stage in the development of Cat5, where one or two of the units are used in an attempt to use all the eNodeB resources while other handsets or UE also require to be served.
