Huawei Announces Breakthrough on HSUPA As the Single-User Uplink Peak Data Rate Exceeds 20Mbs
Published on:
Huawei has announced that a demonstration it conducted broke the HSUPA (High Speed Uplink Packet Access) record for peak single-user uplink data rates with 20Mbs 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.
The record-setting 20Mb/s uplink achievement for the 16QAM higher-order modulation technology and the DC convergence technology was based on Huawei's UMTS algorithms.
