[Shenzhen, China, 20 October, 2011:]: Huawei, a leading global information and communications technology (ICT) solutions provider, today announced the successful launch of a TV White Space (TVWS) LTE TDD system trial. This innovative TVWS LTE TDD solution provided by Huawei will enable more widespread usage of TVWS spectrum and will improve spectrum efficiency.
As a result of the proliferation of smart devices, which has led to a much higher utilization of spectrum resources, mobile operators worldwide are now confronted with the urgent problem of limited spectrum resources. The search for new spectra has put a spotlight on TVWS – the spaces left between channels to limit interference. This spectrum, abundant in every country and vastly underused, offers many benefits for mobile broadband use, including large bandwidth, excellent penetration and propagation, and extensive coverage.
In 2008, the U.S. Federal Communications Commission (FCC) approved the unlicensed use of TVWS. This decision opened the door for new devices and applications with support for TVWS to hit the U.S. market. As other regions and countries move toward finalizing regulations and standards for TVWS, the spectrum will eventually fulfill mobile broadband requirements and more applications will be created.
Huawei began this TVWS LTE TDD system development and verification test in 2009. After two years, the first phase of the laboratory trial was successfully completed in August 2011. The next phase—the system performance and interference coordination test and field trial—will be finalized in mid-2012.
“The LTE TDD system can take full advantage of TVWS bandwidth and enhance spectrum efficiency,”said Mr. Tan Zhu, director of wireless strategy department, Huawei. “We have seen that our TVWS LTE TDD system offers broader coverage and fewer sites, reducing both capital and operational expenditures. This LTE TDD system will benefit network and service providers by offering a combination of strong operation and management capability, a mature industry chain, and variety of deployment scenarios. We are excited to undertake the second phase of the trial next year.”
