Datang Telecom Technology Co. Ltd. (DTT) has won an order to manufacture and ship 1588v2-compliant packet synchronization equipment to China Mobile. The first deliveries are to be completed within next month. Conemtech AB, Stockholm based semiconductor company, is a lead technology partner with DTT.
IEEE 1588-2008 is a packet-based network synchronization technology that distributes information about time and frequency from master clocks being synchronized to a reference time sources, e.g. Global Navigation Satellite Systems like GPS or Beidou. In large deployments slave clocks will use a combination of network and satellite based technologies, or local high accuracy oscillators, to complement and act as backup in the event of signal drops. IEEE 1588 technology delivers this synchronization to the lowest cost. A highly synchronized mobile network delivers increased capacity and quality of service, as it allows for greater call capacity and data bandwidth. The IEEE 1588 technology also provides for lower latencies for the individual subscribers and fewer call drops when moving between cells in the system.
Conemtech and DTT said their success with China Mobile comes after a series of development iterations and extensive testing in the operator’s networks. The final system fulfills the requirements of the operator, adapting this world-wide standard to the conditions and special requirements of the Chinese market. A version of the system will also be targeted for synchronizing in the Chinese power grid.
“This order is our most important accomplishment recently and is the result of two main developments. On the one hand it is proof of that our microprocessor and miniaturized systems are world-class and on the other hand that the market for the IEEE 1588 technology has reached a critical stage of maturity,” says Conemtech CEO Ola Andersson , “I expect other customers to follow now as large operators show the way. We now see an emerging trend that the traditional SDH type of synchronization is being phased out as the new packet network’s capacity is installed to cope with the increasing traffic from smartphones and other mobile broadband devices.”http://www.conemtech.com http://www.datang.com
