ZTE Corporation has announced the launch of a dual-mode software defined radio product which use HSUPA-based uplink interference cancellation technology to deliver uplink capacity.

The new SDR product is designed to meet a variety of scenario requirements, including indoor macro, outdoor macro, distributed outdoor micro base stations, radio controllers and unified-management systems.

The primary benefit of the solution is that it allows operators to deploy high-capacity base stations and increase capacity without hardware platform changes or device upgrades. In addition, the SDR products offers GSM/UMTS dual-mode networking to provide an evolution path to HSPA+ networking, making the solution a future-proof one.

This technology also provides a significant increase of both the number of voice users and average cell throughput, with users benefiting across various radio conditions. The SDR product solution is expected to be commercially available later in 2011.

“Consumers are increasingly using mobile data services to upload content such as photos and videos to the cloud. This can create challenges for operators in maintaining uplink capacity and a good user experience for their subscribers,” said Zhang Jianguo, general manager of ZTE’s UMTS products.

“By using uplink interference cancellation, the SDR product can mitigate signal interference and increase operators’ cell uplink capacity by up to 50 per cent, which enables them to use their spectrum resources much more efficiently.”
