Huawei Releases Sub-3GHz Evolution White Paper

During the Sub-3GHz Network Evolution Summit held during the Global Mobile Broadband Forum 2022 (MBBF2022), Huawei presented a comprehensive white paper on the evolution of new multi-antenna systems.

Thus, Yang Chaobin, president of Huawei ICT Products & Solutions and Huawei Wireless Solution, launches the One 5G concept and a set of solutions designed to facilitate the evolution of all bands to 5G. “5G is in the fast lane.” For the same reason, the CEO decided to explain everything related to the operation of these new technologies by means of a white paper. So let’s take a look at the content in order to deduce what we can expect from it.

But first, what is the Global Mobile Broadband Forum?

The Global Mobile Broadband Forum 2022 is organized by Huawei, together with its industry partners GSMA and GTI. This annual forum brings together mobile network operators, vertical industry leaders, and ecosystem partners from around the world to discuss how to make 5G a commercial success, as well as other high-priority industry topics such as green development, intelligence, and 5G evolution.

Book’s main content

To begin with, it should be highlighted that this white paper proposes the technological directions of the industry, from sub-3GHz evolution to ultra-wideband and multiple antennas. “FDD across all bands of 5G will provide the user with a better experience, with wider and deeper coverage, as well as improved uplink capabilities.”

On the other hand, this trend will also help operators to simplify the construction of green and smart networks that achieve optimal 5G performance and power consumption overall. 

Therefore, in this regard, the Asian company’s book provides a valuable reference for wireless regulators, mobile operators, consulting analysts, and equipment manufacturers.

Sub-3GHz evolution

In addition, this book describes the directions of Sub-3GHz evolution technology from the perspective of ultra-wideband technology, multiple antenna MIMO technology and multiple RAT (Radio Access Technologies) coexistence technology.

All of which can help users simplify multi-band deployment and maximize network performance with improved energy efficiency. It has proven to be an important technology direction to migrate all bands to 5G. 

Thus, ultra-wideband technology enables multiband deployments within a single box as well as supports pooling of power and spectrum resources, so that cross-band and different RAT coordination is possible with simplified network construction, less interference, and less power consumption and experience.

Other technologies included

Experience with GSM, UMTS, LTE technologies can also be provided. As multiple antenna uses a variety of antenna arrays and spatial diversity to create diverse transmission channels and BF (BeamForming) technology can help operators maximize the benefits of NR networks and overcome the challenge associated with using Sub-3GHz spectrum, address low spectrum efficiency, traffic congestion and various legacy RATs in implementation.

As such, multiple antenna and ultra-wideband technology enables Sub-3GHz to evolve to 5G with better user experience, higher energy efficiency and simpler sites.

What did the company say?

According to the company: “Huawei FDD ultra-wideband and multi-antenna technologies will simplify Sub-3GHz deployment for operators seeking to build mobile networks based on various bands and RATs as well as discrete small-bandwidth spectrum. It supports multiple bands and leverages MIMO spatial multiplexing to greatly improve spectral efficiency, making 5G deployment simple, green and efficient. This way, it will play a critical role in providing the world with intelligent, ubiquitous 5G connections.”
