Vodafone Spain has completed the world’s first commercial implementation of dual-band High-Speed Downlink Packet Access (DB-HSDPA) technology using technology from Huawei. The solution delivers approximately double the amount of UMTS throughput compared to single carrier on UMTS 900MHz.
DB-HSDPA is a 3GPP release 9-defined technology. From the second half of 2015, chipsets that support DB-HSDPA technology have been incorporated into commercial devices. DB-HSDPA capable terminals are able to receive and monitor two bands simultaneously, delivering a better user experience.
On the Vodafone Spain network, there is a single carrier on UMTS 900MHz. The companies noted that UMTS 900MHz can absorb a larger number of subscribers than UMTS 2100MHz. strategy.
“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,” said Peng Honghua, president of Huawei’s UMTS Product Line.
The successful commercial deployment of DB-HSDPA demonstrates Huawei’s ongoing commitment for the supply of innovative techniques in wireless networks to help build the best experience-oriented MBB networks. In addition, Huawei’s patented UX2 interface solution will ensure the application of DB-HSDPA not only at intra-NodeB level, but also among different NodeBs.
