Product features:

1.Spread spectrum and modulation scheme: Support multiple spread spectrum factors, adopt QPSK modulation scheme. It has the features of Code resource easy generation, high anti-interference ability and sufficient code resources.

2.WCDMA system has high receiving sensitivity since WCDMA uses higher spread spectrum code rate, which makes base station to cover longer distance and save network construction cost.

3.WCDMA adopt higher RF bandwidth and spread spectrum code rate. Under the condition of same channel capacity, WCDMA uses less RF devices in the base station which means saves integration cost in every channel.

4.Transmission division assembly: Support multiple transmission division methods such as TSTDSTDSSDT that could effectively improve wireless link performance. It is an important new technology helps to improve downlink coverage and capacity.

5.Compress mode technology: In some slots of one or a few continuous wireless frames, by using compress mode technology they are not to be used for sending messages in these slots. They are to do the inter-frequency measurement and inter-system switch that could better realize inter-system switch between WCDMA and GSM to improve operator service quality. It also owns features like easy site construction, easy maintenance, wider frequency range, better multiplexing, better voice quality, high security, .etc.
