[Shenzhen, China, July 4, 2012]: Huawei, a leading global information and communications technology (ICT) solutions provider, today announced that a demonstration it conducted broke the HSUPA (High Speed Uplink Packet Access) record for peak single-user uplink data rates with 20Mb/s using DC (Dual Carrier) and 16QAM (Quadrature Amplitude Modulation) technologies.
The mobile broadband era of is gradually changing the habits of end users in ways that put higher uplink rate demands on wireless networks. Uplink rates, however, are far lower than downlink rates, which leads to the bottlenecking of user experience of data services like video or image uploading. Huawei set to work on an uplink breakthrough to bring a vastly improved experience to mobile users.
The record-setting 20Mb/s uplink achievement for the 16QAM higher-order modulation technology and the DC convergence technology was based on Huawei’s unique UMTS algorithms. This breakthrough data rate can ensure that mobile users can upload and share video clips very quickly, greatly improving user experience. The uplink rate can also help popularize more and more multimedia services to further promote the robust development of the mobile broadband industry.
