1. Smart Education

    China has attached great importance to education informatization and Internet technologies since the 1990s. Key initiatives in the early days included Education informatization 1.0 and "Three Links and Two Platforms", which were aimed at providing broadband access for each school, quality resources for each class, and online learning spaces for each student, as we ll as building an education resource platform and an education management platform.

    In 2018, China stepped forward, proposing "Education Informatization 2.0". According to this initiative, by 2022, China will deliver teaching applications to all teachers, extend learning applications to every student, ensure digital campus extend learning applications to every student, ensure digital campus construction for any school, improve the level of informatization and the construction for any school, improve the level of informatization and the information literacy of teachers and students, and put in place an "Internet + information literacy of teachers and students, and put in place an "Internet + education" platform.education" platform.

    Networks have fortunately made great strides during this process, as they are fortunately made great strides during this process, as they are the primary infrastructure required to press ahead with informatization in the primary infrastructure required to press ahead with informatization in education.education.


Wi-Fi 6 and All-Optical Ethernet Maximize Outcomes Under COVID-19

    The outbreak and resurgence of COVID19 adversely affected education all over the world since 2020. Educators have realized the urgent need for education that persists everywhere we go. In other words, education must go beyond current expectations and allow students to learn anytime and anywhere. For example, while some students can take online courses and Massive Open Online Courses (MOOCs), and download teaching resources remotely from their dormitories, we have not gone far enough. Immersive teaching powered by state of the art network and VR/AR technologies should be available, providing a highly interactive and engaging experience to students and teachers alike.


    These expectations, however, are hard to meet given the outdated construction and lack of informatization that still persists i n some schools. One of the key reasons is that wired networks are still predominant, and wireless networks are at most used as a supplementary network. Problems such as connection failures, video buffering, and artifacts occur frequently, and the IT depart ment receives one complaint after another. In short, legacy networks cannot meet the demands required to suspend class attendance while still providing equal learning opportunities for students.


    Facing this challenge, many schools have decided to introduce cutting edge network technologies that can stably and reliably support teaching, research, and administration. Doing so helps comprehensively improve network experience and accelerate the construction of smart education campuses.


    To keep up, CloudCampus offers a "Wi Fi 6 + all optical Ethernet" solution for the education industry to upgrade and reconstruct school wireless networks. Figure-1 illustrates the n etwork architecture enabled by this solution.

Smart campus network architecture

Figure-1 Smart campus network architecture


    Innovative full 10GE hybrid optical electrical switches can be used together with hybrid cables at the access layer, supplying both PoE over 300 m and 10 Gbit/s access bandwidth for APs. This combination of optical and electrical not only overcomes the ina bility of a Passive Optical LAN (POL) solution to supply power to APs, but also the inability of an Ethernet cable access solution to upgrade bandwidth. Therefore, it proves ideal for constructing a WiFi 6 transport network in this instance. For student a ccommodation, Huawei's flagship campus core switch CloudEngine S12700E can be deployed at the core of dormitory networks. The switch can manage up to 10,000 WiFi 6 APs, implementing wired and wireless convergence and eliminating the need for standalon e WLAN ACs.


    It should also be noted that the access and core switches support network virtualization with Virtual Extensible Local Area Network (VXLAN). With VXLAN, multiple isolated data services can be deployed on the current transport network on demand, creating one multi purpose converged network while reducing network construction and management costs.



Cloud Management and Intelligent O&M Make Managing Numerous Devices Easy



When it comes to achieving high quality networks, 30% lies in the construction and 70% in O&M. Effective O&M is of the utmost importance for education campus networks. For example, at a top ranked university in China, nearly 10,000 APs and 1000 switches are deployed in a single dormitory area. Tens of thousands of students need to ac cess the network, and so do hundreds of thousands of IoT endpoints, including video surveillance, energy saving

management, asset management, and environment monitoring endpoints. 

    

    In face of this, smart campus construction must consider how to efficiently deploy and manage such a vast number of network devices, how to secure access for numerous users and IoT endpoints, and how to guarantee network quality for multiple services, such as remote education, video conferencing, and pandemic prevention and detect ion.


    In response, Huawei has developed a "cloud management + intelligent O&M solution. This solution is purpose built to manage numerous network devices and endpoints and ensure the network access experience for massive numbers of users in real time. The d ashboard at the information control center presents device statuses and service experience across the campus network in an intuitive manner, as shown in Figure-2


    To maximize the operational and management efficiency of campus networks, Huawei also offers iMaster NCE Campus, an intelligent network management and control system. This system integrates network management, control, and analysis functions and facil itates centralized management and control of devices, users, and services. Conventional solutions require devices to be manually configured and commissioned one by one onsite. iMaster NCE Campus offers automated underlay network deployment, allowing switch es and Wi Fi 6 APs to automatically initiate registration requests and synchronize service configurations from iMaster NCE Campus once powered on. This provides true plug and play for devices and networks, slashing device deployment costs and

shortening de vice provisioning time.

    Huawei's AI powered platform iMaster NCE CampusInsight has completely transformed the way we do network analysis. It collects and analyzes Wi Fi network data and user data in real time, evaluating network health from multiple dimensions and then presenting IT personnel with insights into network status and quality. It allows teachers and students to enjoy seamless access to the network whenever they are connected. Howe ver, if a user does fail to access the network, the platform can trace the protocol to rapidly locate the fault as well as its root cause, providing IT personnel with suggestions to rectify it. More importantly, iMaster NCE CampusInsight constantly learns network models and can predict service trends using big data and AI technologies. Based on these predictions, it intelligently calibrates the radio for Wi Fi networks, creating better WiFi services for teachers and students alike and transforming an admin istration oriented education campus network into a service oriented one.



2. Smart Bank

    With the growing popularity of mobile payments, digital currency will replace cash as the long term means for performing transactions. Digital currency is just one example of the direction the finance industry is taking, and digitization is no doubt a megatrend for the industry.

    

    For financial institutions worldwide, digital transformation is a must given today's policies and fierce market competition. Especially with the ris e of Internet finance, people's access to financial services has changed greatly, resulting in fewer touchpoints between traditional brick and mortar financial institutions and customers. Indeed, banks, specifically their local branches, are hit the hardest by this change.


5G + SD-WAN: Building a "Bridge" for Smart Connectivity in Bank Branches

    Smart bank applications are constantly emerging; for example, Smart Teller Machines (STMs), home banking, live streaming, interactive customer engagement, and even humanoid robots. These new use cases make financial

services more convenient, and reshape service processes across the entire customer e xperience.

    

    Smart banks integrate online and offline banking services, such as mobile banking, social banking, and traditional banking at branches, and offer multiple fun interactive games. Financial services are more engaging than ever, and smart banks are becoming a front line for engaging and productive customer marketing services. The end result is significantly improved transaction handling efficiency, minimized queuing time, and more engaging financial services and transactions.



    But none of this is possible without the WAN infrastructure. While smart banks continuously optimize the financial services experience, they also drive exponential growth in traffic. As such, bank branches have more urgent demands for real time data transmission performance and high bandwidth.


    MSTP private lines are the conventional solution for branches, and are seemingly mature and stable, but offer bandwidths of only 2 to 4 Mbit/s. This falls far short of the ultra large bandwidth required by the wide range of smart applications emerging in finance.


    Compounding this problem, branches have more stringent requirements on mobility and provisioning speed to cope with ever changing business environments. With more than 10,000 branches across the globe, banks need to

find a new way t o improve O&M and management efficiency on such large, complex WANs.


    As shown in Figure-3 , Huawei's CloudCampus Solution uses "5G + SD WAN" technologies to provide high speed interconnections between branches and headquarters and to deliver the ultra high bandwidth required by smart

applications.


    Huawei NetEngine AR enterprise routers are deployed to build dual service channels at the network egress, namely, a 5G link and MSTP private line. This improves the bandwidth of smart branches by 100 times. The 5G link functions as the underlay network, providing the network infrastructure with ultra high bandwidth and ultra low latency for smart banks. SD WAN is use d on top of this 5G link and the legacy MSTP private line to build an overlay network. In this way, high speed channels can be quickly set up to interconnect branches at all levels with the financial cloud. The cloud based iMaster NCE Campus efficiently manages and schedules a variety of applications and automates complex configuration for branches.


    The 5G link can be deployed fast and has high mobility. This means that smart banks can be quickly rolled out and demonstrative services that require mobility can be provisioned. For example, community banks and call centers can be connected through 5G/LTE and the Internet, and temporary financial service branches can be deployed at large event venues to provide onsite financial service assurance.

Application-based Intelligent Traffic Steering for Preferential VIP Assurance



    SD-WAN builds an end to end overlay network to logically eliminate intermediate network nodes. 5G implements one hop access to the cloud for smart banks. Together, these technologies greatly simplify the network topology.


    By fully leveraging the 5G link and MSTP private line, SD WAN provides reliable access to the cloud. SD WAN accurately identifies key applications and detects application quality in real time. Doing so facilitates intelligent multi factor optimization of network paths and ultimately ensur es that key applications always run on the optimal links. As shown in Figure-4 , smart banks often have dozens of financial applications. SD WAN can quickly identify key financial applications, monitor their path statuses in real time, and dynamically schedule their traffic over optimal paths.

Intelligent O&M and Unified Cloud Management

    SD-WAN orchestrates and schedules link an d bandwidth resources for applications network wide. SD WAN can accurately and intelligently identify abroad range of applications such as key financial applications, IoT applications,

and Internet applications in real time; it also presents real time key indicators including the status and bandwidth usage of applications, links, sites, and devices. This facilitates capacity expansion, link optimization, and branch

adjustment, thereby optimizing network investment and planning.


    What's more, iMaster NCE Cam pus centrally manages LANs and WANs. It automates the entire process from network provisioning, service deployment, and fault locating, all the way down to routine inspection. iMaster NCE Campus also provides insight into the network topology using Geograp hic Information System (GIS), and delivers multi dimensional visualized reports (on the basis of links, applications, users, sites, and devices). As such, it helps quickly locate network faults while optimizing network policies. These benefits mean financial services can be carried on one simple and reliable network.




3.Smart Retail

    Driven by new technologies, such as AI, IoT, and big data, the retail industry represented by shopping malls, supermarkets, and retail chains is undergoing profound transformat ion to adapt to diversified and personalized requirements of consumers. A viable way to improve retail efficiency is to digitalize it by integrating technologies with the Internet. To this end, two areas need digitization: operations and consumer experience.


Plug-and-Play for Fast Provisioning 

    As competition in the market heats up, retailers are finding it increasingly difficult to succeed while basing their entire business on only one store. For this reason, many retailers prefer to operate multiple stores . Since its emergence in the last century, retail chains have quickly grown with a strong momentum. This new business pattern has a profound impact on the consumption habits and life style of modern society. The key to success for retail chains lies in the irunmatched replication. They can quickly replicate into multiple stores and expand reach into global markets. For example, a famous milk tea brand in China saw a 4 fold increase in the number of stores in two years. Undoubtedly, the key strategy and top priority for retail chain development is to quickly open new stores.

    

    In response, Huawei launched its Cloud Managed Network Solution tailored to retail chains, as illustrated in Figure-5. This solution slashes network deployment time and the error rate. With it, retail chains are able to quickly open new stores and implement digital operations. Once devices arrive at stores, engineers simply need to scan device barcodes to record the device information in iMaster NCE Campus. Devices can be onboarded in minutes, and once onboarded, they do not require manual configuration. Instead, preset configurations are delivered directly from iMaster NCE Campus. This im plements Zero Touch Provisioning (ZTP) for onsite devices and shortens store provisioning time from weeks to just days. Faster rollout and operations in the new store translate into accelerated Return on Investment ROI.


Cloud managed network

Figure-5 Cloud managed network



Unified Management of Global Stores Retail chains

    Retail chains often have to face a range of management and O&M issues. One reason for this is that IT and IP devices are not centrally managed. The internal network of a store and the headquarters network belong to different

depa rtments, resulting in decentralized management. Heavy on site O&M requires high skills and leads to high costs. If a network fault occurs, IT engineers need to locate and rectify the fault on site. However, faults are difficult to locate and the network ta kes a long time to recover. 

    

    Huawei iMaster NCE Campus is a good fit to help address these issues. It centrally manages stores all around the world through the Internet and cloud. It also offers comprehensive automatic management from end to end.


The iMaster NCE Campus interface gives users a clear view of information such as the online statuses of devices and users, as well as user traffic usage status and device faults. Users can also search for devices by tenant, device, or device group to view their stat us in real time. GIS and the CloudCampus APP help O&M engineers quickly pinpoint network devices. A graphical dashboard is also provided.


Application Integration for Precision Marketing


    In recent years, e-commerce has grown to an enormous scale, and it has taken a toll on offline retail. Brick and mortar retailers need to innovate and transform, and they need to start now. While they realize the need to move into online marketing, they lack effective online operation and business models.


    To this end, most retailers implement wireless networks in the hopes of improving customer experience. Specifically, they seek to provide coupons with alow level of entry; that is, supporting multiple authentication modes such as social media, SMS, and a mobile app to attra ct customers and increase sales.


    Once a customer has bought in to this experience, personalized advertisements can be pushed to customers depending on their region and assigned category, along with discounts and promotions. 


    With network statistics, activity planning and shop layout can also be adjusted on the fly to take advantage of where consumers tend to walk and dwell. This facilitates effective marketing and decision making.


    Figure-6 illustrates open Application Programming Interfaces (APIs) supported by iMaster NCE Campus for easy integration into retail applications. iMaster NCE Campus offers more than 680 open APIs across more than 50 industry solutions and 30 application scenarios. APIs include value added service APIs, location based service (LBS) APIs, authentication and authorization APIs, network automation APIs, and network O&M APIs. With this range of open APIs, enterprises have the freedom t o integrate partner applications and precision marketing however they choose.


Figure-6 Open APIs

Figure-6 Open APIs



    To explain how this may apply to the real world, we can look at value added service APIs. These APIs provide third party partners with terminal related data, with wh ich they could profile customers, assign tags to customers, and personalize services accordingly. This could include pushing targeted information or marketing to the customer. As another example, LBS APIs aggregate terminal location data collected by APs, and periodically send such data to the partner's LBS analysis platform. This platform parses and analyzes LBS data with a series of algorithms, ultimately offering value added services such as heat maps, path tracing, and customer flow analysis for end cus tomers.



4.Smart Factory

    In 2018, the Ministry of Industry and Information Technology (MIIT) in China released a first of its kind Industrial Internet Development Action Plan (2018-2020). Over the past three years, industrial Internet has been frequently discussed in the industry and even featured in four of the government's work reports in a row, highlighting its significance at the national level. Networks are foundational to the development of industrial Internet. The first step towards industrial Internet is to achieve fully wireless inside factories and transform factory terminals into IP based ones. CloudCampus keeps up with this change by leveraging industry leading Wi Fi 6 technology to reconstruct wireless networks and unify the many different prot ocols used by industrial terminals into IP.

Wi-Fi 6 and Lossless Roaming Get AGVs Free from Interruptions

    Annual shopping events like Black Friday and Double Eleven are really challenging for logistics, warehousing, and e commerce. To improve goods sorting and transportation efficiency, many industry players are turning to automated guided vehicles (AGVs) for help. Although AGVs can transport things with a higher efficiency, they often get "stuck" due to network packet loss and delay. Once stuck, collisions , accidents, and even chaos can 

    

    Network delay or packet loss is the main issue causing AGV interruptions, especially during roaming. AGVs need to obtain key instructions from the network when moving at high speeds. This includes questions such as:

  • Where I am

  • Where I will go

  • How will I go there

    Even a small rate of packet loss (probably over 1%) may sometimes cause AGVs to become disconnected or stop responding. To change this, Huawei proposes the "Wi-Fi 6 and lossless roaming" solution, as illustrated in Figure-7


Figure-7 Wi Fi 6 and lossless roaming solution

Figure-7 Wi Fi 6 and lossless roaming solution



    With conventional wireless networks, the packet loss rate of AGVs is usually greater than 1%, a nd roaming only works about 90% of the time. Huawei's "WiFi 6 and lossless roaming" solution outperforms this by integrating key

technologies such as lossless scanning, lossless roaming, and reliability guarantee mechanisms. It reduces the packet loss of AGVs to zero during roaming, ensuring that the production network can run stably 24/7.


    Figure-8 illustrates the AGV workflow at a typical automated warehouse. Customers place an order online, and the generated order information is immediately reported to the warehouse IT system. Then, goods are automatically picked up and packaged under the control of the AGV scheduling system. The automatic sorting system then instructs AGVs to deliver the packages according to their labels to a specified logistics box and then to vehicles for delivery.

Figure-8 AGV workflow at an automatic warehouse


Figure-8 AGV workflow at an automatic warehouse


    Huawei's "WiFi 6 and lossless roaming" solution improves terminal roaming reliability, reduces network latency and packet loss rate, and greatly enhances network service capacity. The resulting benefits include dramatically reducing AGV interruptions caused by poor network quality, scheduling AGVs in an orderly fashion, and significantly increasing network loads. 

    For example, this solution has proven highly productive at a warehousing enterprise. Specifically, the number of AGVs that the Wi Fi network can accommodate increased from 550 to 750, the number of work orders generated per day g rew from 30,000 to 40,000, and overall efficiency was improved by 30%. More importantly, the entire network is basically O&M free.


Wi-Fi 6 Industrial CPE Makes Equipment Wireless for Flexible Manufacturing


    The manufacturing industry is facing many challenges, including more complex production environments, fiercer competition, stricter supervision, and more demand for comprehensive security risk management.


    To address these challenges, manufacturers have begun to transform towards intelligent produc tion. They are looking for an all in one solution that integrates planning, operation, and monitoring to achieve secure production and protect its people, environments, assets, and intellectual property rights.

    However, a key challenge lies ahead ensurin g that legacy factory equipment can be operated smoothly in the next generation system.

Figure-9 Wi Fi 6 industrial CPE

Figure-9 Wi Fi 6 industrial CPE


    The WiFi 6 industrial CPE illustrated in Figure-9 is the ideal solution for this challenge. Built on broadband capabilities offered by the intelligent edge computing system, the Wi Fi 6 industrial CPE offers the most comprehensive assurance for E2E production traffic. This means production is eas ier to manage and enterprises can quickly respond to internal, external, and market changes. In particular, Wi Fi 6 technology assists the manufacturing industry with interoperability to interconnect devices across systems, production zones, and regions. This translates into higher efficiency and drives the arrival of more intelligent manufacturing and service systems.


    In factories, the WiFi 6 industrial CPE helps transform production lines and their equipment into intelligent and fully wireless equipment. With the Wi Fi 6 i ndustrial CPE, production line deployment is more convenient than ever. Its wireless access features comprehensively cover user requirements for wireless access and help enterprises flexibly and conveniently embrace intelligent devices and new industry use cases.
