The French division of mobile operator Orange has begun testing IPWireless' UMTS TDD (12Mbps) technology, which is being touted as a possible rival to WiMAX and HSDPA (Super 3G):
The trial one of the first in Europe will involve companies based in the Lille business area. Orange hopes to test the real-time performance of TDD, including the coverage area and the number of simultaneous users that can be supported. TDD runs within the 3G, or UMTS, specification.
In Britain, as in many other countries, the operators who won 3G licences were allocated two portions of 'paired bandwidth' called FDD, to be used for voice calls and data services (such as Vodafone's 3G Mobile Connect offering). Most of them also received an extra piece of spectrum, the TDD, which could be used to provide extra network capacity once operators had filled up their FDD allocation.
IPWireless says that TDD can be more than a simple buffer. The company's service uses it as the backbone of a separate high-speed data service that it claims will be faster than is currently possible using FDD.Regular readers will no doubt recall a similar technology being developed and tested in Germany, although lots of competing standards isnt a helpful prospect for consumers.
