Vodacom and Huawei Jointly Fulfill DC-HSUPA Whole-Network Deployment to Deliver Superb 3G Experience

[Shenzhen, China, October 27, 2016] Vodacom, a leading African telecom operator, and Huawei jointly achieved whole-network deployment of a Dual-Carrier High-Speed Uplink Packet Access (DC-HSUPA) solution in South Africa. DC-HSUPA offers an uplink peak rate twice as fast as single-carrier uplink peak rates on UMTS networks. A doubled peak rate puts Vodacom in a better position to deliver a superb mobile internet experience by combining advanced 4G networks with the fastest 3G networks.

Mobile internet is advancing with each passing day. With the dramatic increase in sharing pictures and videos on social networks, uplink data rates are crucial to ensuring the speed and quality of sharing activities. There are two ways commonly used to increase the UMTS uplink data rate: improve spectral efficiency and increase uplink spectral bandwidth. DC-HSUPA overcomes the one-carrier limitation and enables data to be transmitted over two 5 MHz carriers, allowing higher uplink data rate.

As an HSPA+ feature introduced in 3GPP Release 9, DC-HSUPA aggregates two continuous carriers to give doubled uplink data rates. Therefore, the uplink peak data can be increased from 5.76 Mbit/s to 11.5 Mbit/s on UMTS networks with this technology. At the present, this technology is supported by the world’s major chip vendors, and the terminals supporting DC-HSUPA are also available on the market.

Vodacom is always committed to providing high-quality user experience. It has already completed the commercial deployment of Dual-Carrier High Speed Downlink Packet Access (DC-HSDPA) in South Africa to improve downlink user experience. An overall DC-HSUPA deployment not only offers higher uplink data rate services with shorter delays, but also helps balance traffic loads between carriers to improve the uplink capacity of HSPA+ networks.

Yu Xiao, President of Wireless Network UMTS Product Line of Huawei, said, “Huawei and Vodacom have a close cooperation. We have jointly completed the DC-HSDPA deployment. Recently, we jointly achieved the overall deployment of DC-HSUPA. With these deployments, we are able to help Vodacom offer high-speed service experience in both the uplink and downlink. In the future, we will continue our cooperation with Vodacom in our endeavor to maximize network efficiency and build networks that deliver better user experience.”

In addition, Huawei has helped a number of global telecom operators achieve Dual-Band High-Speed Downlink Packet Access (DB-HSDPA) commercial deployment. DB-HSDPA enables 3G networks to support coordination across frequency bands to thereby increase the benefits of multi-carrier solutions. With scaled commercial deployment of DC-HSUPA and DB-HSDPA, UMTS networks are ushering in the era of multi-carrier, multiband coordination. Huawei will continue to work together with global operators to pursue constant innovations that can deliver the best service experience to the world’s 3G subscribers.
