Nokia and Beijing TA Trial Dual Band in Live Network

DCS 1800 is a derivative of the GSM technology, operating in the 1800 MHz frequency band. As 900 MHz GSM bands begin to fill, the DCS band can be deployed to extend capacity. The GSM/DCS dual band technology is an ideal solution for operators to increase capacity in urban areas and traffic hot spots. The GSM bandwidth can be used to build the basic coverage, while DCS 1800 extends capacity to meet local high subscriber numbers and traffic in the network. The wider frequency band and smaller cell size of DCS 1800 allows more capacity, higher traffic density and more flexibility in frequency planning.

Using Nokia’s common GSM/DCS network elements, a DCS base station can be integrated to an existing GSM network without any new hardware investments into network management, switching subsystems or base station controllers. The common DX-200 switching platform also ensures that Nokia's value-added features and services are available for both GSM and DCS subscribers.

Mr. Folke Ahlbäck, Vice President, People’s Republic of China, Nokia Telecommunications says, that the GSM/DCS dual band trial, shows Nokia’s commitment to take the GSM/DCS technology further into the next century. “Innovative solutions are called for when the number of mobile subscribers increase and their service requirements grow. This trial is also an important milestone for Nokia. We are keenly participating in the further development of telecommunication systems in China.”

Nokia PrimeSite base station was launched in 1995, and both GSM and DCS versions have been commercially available since Autumn 1996. Nokia PrimeSite revolutionizes the traditional base station concept by offering one compact model with integrated antennae and sufficient output power for a large variety of indoor and outdoor applications. It is an ideal solution for areas where high capacity service is most needed.
