Huawei Announces Large-Scale Commercial Deployment of UMTS Flexible Carrier Bandwidth Solution that Improves Spectrum Efficiency up to 24%

Huawei, a leading global information and communications technology (ICT) solutions provider, announced the industry’s first successful large-scale commercial deployment of a UMTS Flexible Carrier Bandwidth solution on five networks in Hong Kong, Spain, Australia, Canada, and Poland. The solution improves spectrum efficiency up to 24% to help operators cut back on costly spectrum fees and enable great business successes.

The next decade is expected to see mobile broadband traffic grow 500 times. UMTS remains a mainstream mobile broadband standard due to its inherent advantages in providing capacity, coverage, and user experience. A standard UMTS network requires at least 5MHz of spectrum resources to deploy, but with Huawei’s UMTS Flexible Carrier Bandwidth solution, a UMTS networks can be deployed with only 4.6MHz, 4.2MHz and 3.8MHz of spectrum resources. This improves spectrum efficiency up to 24% to help operators solve spectrum challenges related to refarming for GSM/UMTS 900MHz and GSM/UMTS 850MHz. Such highly efficient spectrum re-usage enables operators to maximize returns on their investments.

The Huawei UMTS Flexible Carrier Bandwidth solution also allows for high quality network performance for deployment scenarios below 5MHz of bandwidth. This is made possible by innovative technologies developed for spectrum planning, interference cancellation, interference control, and traffic migration. The UMTS Flexible Carrier Bandwidth solution does not depend on devices, so operators can quickly deploy large-scale commercial networks.

Ying Weimin, President of Huawei GSM&UMTS&LTE Wireless Networks, said: "Huawei is the only vendor to successfully deploy a UMTS Flexible Carrier Bandwidth solution for a large-scale commercial network. Huawei will continue to focus on its customers’ needs and will continue to deploy solutions that support smaller bandwidths. Huawei is leading UMTS technological innovation by providing the best user experience and promoting the development of the whole mobile broadband industry."

Huawei’s industry-leading solutions and extensive expertise in commercial network deployment has led the company to deployed more than 150 commercial SingleRAN networks and more than 250 commercial UMTS networks worldwide.
