Vodafone Spain has partnered with Huawei to complete world's first commercial implementation of dual-band High Speed Downlink Packet Access (DB-HSDPA) technology. The solution is touted to deliver approximately double the amount of UMTS throughput compared to single carrier on UMTS 900MHz.
Throughout Europe, UMTS 900MHz is the primary UMTS band to be deployed in the future. Due to the coverage advantages provided by low frequency bands, UMTS 900MHz can absorb a larger number of subscribers than UMTS 2100MHz. The combination of UMTS 900MHz and UMTS 2100MHz will be an important part of European UMTS strategy.
According to Huawei, DB-HSDPA which is a 3GPP Release 9-defined technology improves the experience for subscribers on UMTS networks in the 900MHz band. From the second half of 2015, chipsets that support DB-HSDPA technology have been incorporated into commercial devices that are capable to receive and monitor two bands simultaneously, delivering a better user experience.
Huawei has patented UX2 interface solution will ensure the application of DB-HSDPA not only at intra-NodeB level, but also among different NodeBs.

Huawei and Vodafone have cooperated closely to ensure the successful commercial deployment of DB-HSDPA. We will endeavor to assure the provision of innovative solutions, and accelerate the pace and scale of DB-HSDPA's commercial application to benefit more subscribers.
