Huawei announced the launch of a TV White Space (TVWS) LTE TDD system
trial. The 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
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 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 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,” Zhu added.
