LTE TDD (Long Term Evolution Time Division Duplex) or also known as TD-LTE is part of the 3GPP specifications for the next generation cellular technology. In China, TD-LTE will be an evolution from TD-SCDMA and will provide for asymmetric needs of mobile data usage and allow use of unpaired spectrum.
Agilent provides powerful and scalable design and test platforms that support the TD-LTE Radio Access Network (RAN) eNode B stations, and User Equipment (UE) development lifecycle. So, as you take TD-LTE forward, Agilent clears the way.
