JANUARY 30, 2011 -- Conemtech AB and Datang Telecom Technology Co. Ltd. (DTT) won an order from China Mobile, an operator the Chinese market, for 1588 packet network synchronization equipment. The first deliveries are to be completed next month.
IEEE 1588-2008 packet-based network synchronization technology will be used in the new generation of mobile networks, says a Conemtech spokesperson. The technology accurately distributes information about time and frequency from master clocks being synchronized to a reference time sources; e.g., Global Navigation Satellite Systems, such as GPS or Beidou.
“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.”
"The Chinese telecom market is increasing at even higher rates," says Zhong Dingsi, chief product manager for timing products in Datang Telecom Technology Co. Ltd.
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. A highly synchronized mobile network delivers increased capacity and quality of service, as it allows for greater call capacity and data bandwidth.
IEEE 1588 technology provides for lower latencies for individual subscribers and fewer call drops when moving between cells in the system, the spokesperson continues. The final system fulfills the requirements of the operator, adapting the standard to the conditions and special requirements of the Chinese market. A version of the system will be targeted for synchronizing in the Chinese power grid.
