Huawei's Power Digitalization 2025 Summit


Back in October, Huawei held Better World Summit 2020 (a.k.a. "Win-Win Future" Global Online Summit). The theme of this online summit was "Power Digitalization 2025”. Experts and operators shared their ideas, vision and challenges. The following summary was shared by Huawei:

Today, how should global operators respond to opportunities and challenges brought by changes in the digital world, under the rapid development of digital technology and digital economy.

“Energy, as the foundation of the digital world, has become a key part and an important point of competitiveness in the digital economy.” Zhou Taoyuan, President of Digital Power Product Line, Huawei, pointed out that “The entire industry needs to attach greater importance to energy”

With the rapid development of emerging technologies such as 5G, cloud, AI, big data, and the IoT, a digital transformation has kicked off, opening the digital age where things are sensing, connected, and intelligent, "ubiquitous Connected, omnipresent intelligence" is becoming a reality. This has thrown the development of 5G and big data centers into the spotlight. But at the same time, the large-scale and rapid construction of 5G and data centers have brought huge challenges to energy infrastructure, such as increasing energy consumption, long construction periods, and high operation and maintenance costs.

“Pay-as-you-go model is becoming more popular in many countries, as data center owners are looking to a decrease their investment and turn their Capex into Opex. And that goes also for a number of other services as part of running and maintaining data center.” Lilia Severina,Global Major Accounts Director of Uptime Institute,talked about the insights into data center trends at the meeting. “Existing site energy facility cannot meet the power demands of 5G sites. There is a pressing need for reform and innovation in this area.Digitization,intelligent and integrated 5G power system enable faster, more affordable, and simpler 5G network deployment.” Liu Baochang, Deputy Director of Information Energy Department, China Mobile Group Design Institute Co., Ltd, expressed his opinion on the development trend and insights of site power in the 5G era.

Violaine Petit, Sales and Marketing VP of CRT Informatique, shared an interesting case about building data centers of CRT in a castle.“CRT did not just want to build something regular. We wanted to be different. We also wanted to invest in a meaningful project. Based on our business development and rejuvenating the castle, CRT successfully deployed two data centers in the castle to meet the dynamic digital development requirements of government and enterprise users. It can be said that the castle data center not only expands CRT's business boundary, but also can protects the country's cultural heritage, can be said to be two birds with one stone.”

Today, people lead a convenient life because of development of science and technology, while they also worry about the environment. How do we transit towards a net-zero carbon economy? Alberto Carrillo Pineda, Director of Science Based Targets, CDP, has his own view. “This includes changes in policies, technologies, economic structures and patterns of production and consumption, but the most important thing is that we change the way we live today. One of the changes is energy transition. Transitioning from fossil-based to clean and renewable energy and phasing out CO2 emissions in other parts of our economy.”

Zhou Taoyuan said, “Huawei integrates traditional power technologies and digital technologies to achieve power digitalization. In this way, we can use ‘Bit to manage Watt’, and provide simple, green, smart, and reliable digital power solutions to solve challenges faced by traditional power industry. ”

Fang Liangzhou, the Chief Marketing Officer of Huawei Digital Power Product Line, Huawei, said“Huawei uses a target network architecture to guide the planning, construction, O&M, and operation of digital power infrastructure, driving the rapid development of the digital economy. Concerning site power, Huawei proposes implementing 5G without increasing site power-related OPEX, and aims to reduce costs from three aspects as well as tapping into new sources. As for data centers, Huawei proposes a simple, green, smart, and reliable next-generation data center facility that uses the "four reconstructions" initiative to tackle issues such as long data center construction period, high energy consumption, and challenging O&M.”

In the future, Huawei will keep cooperating with global operators to face the challenges and seize the opportunities brought by the digital world. Huawei aims to inject green power into operators and help them grow business sustainably in the future.

Radio Design Webinar: Optimising Your 700 MHz Deployments

 


Radio Design, the award-winning market leader in the provision of wireless infrastructure sharing solutions and RF filter systems, hosted a webinar last week focused on the deployment of the 700 MHz frequency band. This new 700 MHz spectrum is in great demand across the world, mainly due to its long anticipated use as low band 5G spectrum. The webinar explores the potential of this band, as well as how to prepare for potential challenges when deploying.

For people who are familiar with our trainings, we divide the spectrum into three layers, the coverage layer, the capacity layer and the high-throughput layer. 700 MHz is the most popular coverage layer spectrum worldwide.

The slide above from the webinar talks of the recent Austrian 5G Spectrum auction that we blogged about. See tweet below for details

In the webinar, slides and video embedded below, Radio Design’s founder – Eric Hawthorn – kicks things off by analysing the benefits of deploying the 700 MHz band in the real world, before passing over to Global Engineering Director – Steve Shaw – who explores some of the technical problems which can arise, as well as some of the solutions. Last but not least, COO and co-owner of Keima – Iris Barcia – provides her insight into the benefits of deploying the 700 MHz band.

Mobile Network Infrastructure Sharing in Japan over Electric Power Infrastructure

On the 3G4G Small Cells Blog, I have written about the Autralian operator Telstra trialing small cells on Tasmania’s power poles to fix mobile black spots. This looks like a similar initiative in Japan but at a much larger scale.

KDDI have an announcement in Japanese here but Rakuten has one in English:

TEPCO (Tokyo Electric Power COmpany) Power Grid, Incorporated, KDDI CORPORATION, SoftBank Corp. and Rakuten Mobile Network, Inc. announced that the four companies have reached an agreement to collaborate on trials of base station site and equipment sharing utilizing TEPCO PG’s utility poles and other electric power infrastructure, ahead of the introduction of 5th generation mobile communications systems (5G) in Japan. The trials are due to be begin in the first half of FY2019.

5G utilizes high frequency bands in order to enable higher speeds and greater capacity. As a result, the number of base stations required for 5G is expected to be larger than for 4G. The growing number of base stations not only creates difficulties in securing installation locations, but also calls for consideration on the impact too many antennas and other equipment might have on the landscape.

TEPCO PG has been working together with KDDI to explore the shared utilization of utility poles and other electric power infrastructure and base station equipment between mobile network operators, and as preparations are now complete, the companies are set to begin the trials using actual equipment.

The trials, which SoftBank and Rakuten Mobile Network are also set to join, aim to verify the feasibility of location and equipment sharing between mobile network operators. Specifically, the trials will evaluate the equipment, layout, workability, serviceability and the level of radio interference resulting from sharing the antenna for base station installations on utility poles. There are also plans to expand the number of companies participating in the trials to include other organizations planning to utilize 5G in the future.

Sharing utility poles among a number of mobile network operators makes it possible to flexibly build out base stations in urban areas and rapidly launch services in rural areas. It is also expected to address the issue of securing locations for base stations and lowers the impact of base station equipment on the landscape.

Through the trials, TEPCO PG, KDDI, SoftBank and Rakuten Mobile Network aim to reduce the infrastructure construction costs and contribute to the smooth nationwide introduction of 5G.
