5.5G networks: what are they and how is it different from 5G – Technology News – Technology

The Chinese technology company Huawei proposed an evolution of the fifth generation networks (5G) named ‘5.5G’, which it would focus on improving connections to enable industrial use and in areas such as autonomous driving.

At a telecommunications forum held by the company in the eastern Chinese city of Shanghai, Huawei’s investment review board chairman David Wang said that 5G will be the mobile standard in the world before 2030 and that this technology could continue to be used until 2040.

“During the 5G life cycle, we need to continually improve their capabilities”He urged the forum attendees, including senior executives from major Chinese telephone companies and industry associations.

Wang pointed out that the objective that his company, which is among the world leaders in the development of 5G technology, has set is that in the coming years the so-called “internet of things” skyrocket your number of connections to 100,000 million, a figure much higher than that allowed by cellular networks, which currently support about 1,300 million.

But nevertheless, that goal is still elusive for 5G networks due to “shortcomings” in areas such as positioning or upload speed: “We cannot meet the requirements of various assumptions,” acknowledged the Huawei executive.

Therefore, the technology company proposes to replace the current “triangle” of specifications that make up 5G networks – made up of eMBB (improved mobile bandwidth), URLLC (ultra-reliable low latency communications) and mMTC (massive machine communications) – by a “hexagon” in which three more would be added.

Massive connections, low latency and positioning

The new rankings for 5G services that Huawei is looking for Supported by the mobile industry are UCBC (Upload Centered Broadband Communication), RTBC (Real Time Broadband Communication) and HCS (Combined Communication and Senses).

The first two would be focused on 5G industrial applications, which need reliable networks that support a high number of simultaneous connections and that allow, for example, real-time control of machinery.

In figures, UCBC would multiply the bandwidth for uploads by 10 while RTBC could reduce the latency to just one millisecond. On the other hand, HCS would aim to complement the positioning systems for autonomous vehicles or dronesSince, Wang recalled, current systems such as GPS are not effective for situations such as driving in tunnels.

The executive also revealed plans to increase the spectrum currently used in 5G networks over the next 15 years and to “decouple” download and upload connections, as well as to integrate these next-generation networks with developing technologies such as artificial intelligence.

Since 5G has only been in operation for over a year, Wang wanted to calm companies in the industry: “The 5.5G is just a name, we could have called it 5G Plus or 5G Evo. (…) It will be a smooth transition between the (different) generations of standards, which will evolve in a way that also protects investments ”.
