What is TD-SCDMA and is it compatible with 3GSM/W-CDMA?

There were two variants of 3GSMs air interface defined by the ITU from the outset based on FDD (Frequency Division Duplex) and TDD (Time Division Duplex). TD-SCDMA, developed in China , is an example of the latter TDD interface. The FDD and TDD variants are naturally compatible – they were designed that way – and its compatibility is recognised by the decision to standardise TD-SCDMA through the 3GPP. When deployed together TD-SCDMA and 3GSM, minimise the duplication of network elements.
