Vodafone Spain and Huawei Technologies claim to have completed the world’s first commercial implementation of dual-band HSDPA (DB-HSDPA) technology. In a press release confirming the development, the Chinese vendor noted that this solution delivers approximately double the amount of UMTS throughput compared to single carrier on UMTS 900MHz. With DB-HSDPA – which is a 3GPP Release 9-defined technology – said to improve the experience for subscribers on UMTS networks utilising the 900MHz band, the release also noted that chipsets supporting the technology have been incorporated into a number of commercial devices since the second half of 2015. In addition, Huawei’s patented UX2 interface solution will reportedly ensure the application of DB-HSDPA not only at intra-NodeB level, but also among different NodeBs.
Commenting on the technology deployment, Peng Honghua, president of Huawei’s UMTS Product Line, said: ‘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.’
