Huawei has sketched out plans for what it's calling 5.5G, calling for new standards to support high-speed uplinks, drones and hundreds of billions of connections.
 

Huawei's executive director, David Wang, said there was so far no sign of "5G changing the world," as the popular Chinese saying has it, although it had outperformed 4G in mobile broadband.
 

But its weaknesses include the lack of high-bandwidth uplink and its ability to handle large-scale and diverse connection scenarios.
 

"We want to see hundreds of billions of connections on the cellular network, but there's still a big gap. What can we do to change its capabilities?" Wang asked.

During annual Mobile Broadband Forum Huawei recognizes a golden decade of 5G outlining priorities across industries while previewing vision for a 5.5G eraDuring annual Mobile Broadband Forum, Huawei recognizes a “golden decade” of 5G, outlining priorities across industries, while previewing vision for a 5.5G era

Speaking at the Huawei-GSMA Mobile Broadband Forum on Friday, he offered three new potential categories for standards.
 

The first, Uplink Centric Broadband Communication (UCBC), would deliver a 10x increase in uplink bandwidth.
 

It would enable massive IoT and industrial control and would accelerate enterprise digital transformation.
 

Real-Time Broadband Communication (RTBC) would provision for large-bandwidth and low-latency scenarios, making immersive experiences possible, Wang said.

5.5It would aim to deliver 1ms latency to support AR, VR, XR and holographic apps.
 

The third category was Harmonized Communication and Sensing (HCR), aimed at connecting autonomous cars and civilian drones.
 

"In the connected car scenario, we need not only high reliability but also precision positioning," Wang said.
 

Today GPS provides location capability but loses coverage if, for example, a car drives into an underground car park.
 

In the next decade drones would become a major 5G use case – for example, in food and package delivery.
 

华为提出5.5G概念

华为常务董事长汪涛在2020全球移动宽带论坛上提出了5.5G这样一个概念,在这次得演讲中,他提出了定义5.5G,构建美好智能世界。4G从2013年年底开始到现在已经布局了接近7年,这7年里4G应用技术已经发展的相当成熟。而5G距离现在已经有一年多了,目前来说除了网速快了以外,并没有很大的改变。
 

说了这么多,其实5.5G就是5G的加强版。据汪涛介绍,目前的5G已经没有办法满足多样性的物联场景新需求。目前的5G三大应用场景为增强移动宽带、低时延高可靠以及海量大连接,这次5.5G概念的推出,目的就是进一步推动5G的发展。让原本的三大应用场景拓展成六大场景。三个新场景分别是上行能力的构建、宽带实时交互能力的构建以及通信和感知融合能力的构建。
