5G: Huawei and Vodafone Test High and Low Frequency Bands for Dense Urban City Scenarios

Huawei announces that working with Vodafone it has successfully tested 5G mobile connectivity using high and low frequency bands. The companies have demonstrated 1.5 kilometers cell coverage in the lower C-Band and 5Gbps peak throughput for a single user in the high band. It is the world’s first 5G large scale mobility field test of macro coverage in dense urban city scenarios.

The support of mobility capability plays a key role in the adoption of 5G applications such as augmented reality (AR) and virtual reality (VR). It is believed that these applications could require more than 100Mbps average data rates and gigabit speeds for multiusers in hotspot areas. The performance achieved in this realistic environment study is an important reference for next generation mobile network (NGMN) and European trial initiatives to develop and verify solutions for a future 5G commercial launch plan.

Yang Chaobin, President of Huawei 5G Product Line, said: “Huawei and Vodafone are strategic partners and we are now expanding our collaboration. As a leading operator in Europe and many other regions of the world, Vodafone has played a leading role in driving innovation. I am confident that the breakthrough we achieved today is just the beginning, and we expect more exciting results in the future.”

Luke Ibbetson, Head of Vodafone Group Research and Development, said, “The results of these tests are an important development and help further our understanding of how 5G mobile connectivity performs in high and low frequency bands. We look forward to continuing our collaboration with Huawei to test and evaluate emerging 5G technologies.”

In the joint research of 5G New Radio (NR) candidate technologies, it is demonstrated that Filtered-OFDM, Sparse Coding Multiple Access (SCMA) and Polar Code works stably with the massive Multi-User MIMO (MU-MIMO) technology, and the spectrum efficiency is improved approximately three times when compared with LTE. According to the field test, the peak cell throughput of 18Gbps under 200MHz bandwidth in the Sub6GHz band, and air interface latency of 0.5ms in the 5G New Radio user plane were achieved.

5G will be the next generation of mobile technology set to be available by 2020. Huawei and Vodafone signed a 5G strategic memorandum of understanding (MoU) in 2015 and a 5G Technologies Acceleration MoU in 2016.

Industry body defines ‘carrier Wi-Fi’; seeks closer alignment with operators

WBA

 

The Wireless Broadband Alliance (WBA) unveiled what it called a “comprehensive definition” of carrier Wi-Fi, with the aim of “closer alignment” with mobile operators.

Wi-Fi, increasingly used for cellular offload and delivering new services, is an important part of the “mobile experience”, says the alliance.

With that in mind, WBA has identified what it sees as “carrier Wi-Fi” requirements to provide a consistent user experience with “fully integrated end-to-end network capabilities” and “advanced network management”.

The alliance said it brought together nearly 20 of the world’s largest operators and vendors to participate in defining the carrier Wi-Fi vision.

Among those giving input were Accuris Networks, AT&T, BSG Wireless, BSkyB, BT, CableLabs, China Mobile, Cisco, Comcast, Ericsson, Huawei, Intel Corporation, NTT Docomo, Orange, Qualcomm, Ruckus Wireless, SK Telecom, Time Warner Cable and Towerstream.

WBA has also started initial consultations with numerous industry bodies, including the 3GPP, Broadband Forum, GSMA, NGMN and the Wi-Fi Alliance.

“By defining Carrier Wi-Fi, the industry can now work together to put the building blocks in place to deliver advanced Wi-Fi networks,” said Shrikant Shenwai, CEO of the WBA. “This work will help ensure that consumers connecting to a carrier Wi-Fi network will be exposed to the best user experience possible, regardless of time or location.”

“Achieving a common vision for the future of Carrier Wi-Fi and what needs to be put in place to make it a reality is imperative, and we are delighted to be involved in such an important initiative,” added Philippe Lucas, Orange SVP (standardisation & ecosystems development), who led this initiative together with Ruckus Wireless.

“These guidelines encompass input from across the Wi-Fi ecosystem and we are confident that we have addressed the key issues and laid the groundwork for the deployment of these networks. This will secure Wi-Fi’s reputation as one of the most convenient and accessible connectivity options for the end user.”
