Aeroflex says its E500 LTE test system is the first capacity tester to successfully hand over data services between TDD and FDD networks.
According to the test firm, network operators around the world are already commissioning dual standard networks as part of the rapid expansion in TD-LTE (LTE TDD) networks.
As a result a handover capability is becoming important for both operators and network suppliers testing TDD/FDD networks.
The capacity test system is used to load a network with hundreds to tens of thousands of UEs (user equipment), each capable of emulating different radio fading profiles with varying data service mixes in a multi-cell environment.
"Verifying end-user performance when calls are handed over between FDD and TDD networks is crucial for operators to deliver a good customer experience," said Nick Carter, Senior Product Manager at Aeroflex.
Converged TDD/FDD networks will allow mobile operators make more efficient use of spectrum.
Although the TD-LTE market is being driven by China, significant LTE TDD network launches have already taken place in Brazil, Japan, and Saudi Arabia, while operators in Poland, Sweden, and the USA are launching dual-standard FDD and TDD LTE networks.
