New HSPA+ solution promises fifty percent increase in uplink capacity

ZTE, a global provider of telecommunications equipment and network solutions, has announced the launch of a new generation of dual-mode SDR (software defined radio) products which use HSUPA-based (high speed uplink packet access) interference cancellation technology to deliver ‘unsurpassed’ 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 solution allows operators to deploy high-capacity base stations and increase capacity without hardware platform changes or device upgrades. Its SDR products offer GSM/UMTS dual-mode networking to provide seamless evolution to HSPA+, making the solution future-proof.

The technology is also said to provide a significant increase of both the number of voice users and average cell throughput, with users benefiting across various radio conditions. ZTE expects its SDR solution 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 percent, which enables them to use their spectrum resources much more efficiently.”

In recent years, ZTE has achieved breakthroughs in the wireless communications market across the world by leveraging the capabilities of the SDR platform. In Europe, ZTE has ensured the mass delivery of SDR base stations for KPN, Telenor, Telefonica, Optimus and H3G. In China, ZTE is ranked No.1 in terms of the newly added market share of UMTS and second in terms of total market share.
