1.1 Overview of Wireless Retail Development
In recent years, the impact of e-commerce on traditional retail has become larger and larger. Emerging technologies such as the Internet, mobile Internet, cloud computing, and big data will profoundly reshape the business rules of the retail industry. From 2010 to 2012, China ’s online shopping transaction volume increased at an average annual rate of 73.2%; during the same period, the average annual growth rate of total retail sales of domestic consumer goods was 16.6%, and the growth rate was declining. In 2012, the number of online shopping in China has reached 250 million, and mobile The number of users of e-commerce is growing rapidly; data shows that the growth rate of e-commerce is much larger than the growth of traditional retail, and the driving force for growth is due to the surge in online shopping, and more and more people are shopping on the mobile. How to make full use of the advantages of physical retail in terms of environmental experience and services, and integrate the advantages of e-commerce in product categories, customer behavior analysis, and accurate recommendation are issues that the traditional retail industry needs to solve urgently.
When customers walk into a mall, the merchant neither knows who is shopping or what they buy, so the mall cannot dig out valuable data like Amazon. When you do n’t know your customers, Can only wait until the end of life. The people who once knew the customer's needs best were traditional retailers. If they want to get out of the quagmire, the most important thing they should try is to return to the origin.
The new wireless-based technology brings new opportunities to traditional retail. Using Wi-Fi wireless networks to complete offline data collection, this gradually builds a huge customer database and transplants the advantages of e-commerce to traditional retail. It will be a revolution in the traditional retail industry.
The biggest problem offline is not digital. Both user behavior and goods must be digital before they can be calculated. Wi-Fi identification at this stage is the first step in establishing an offline database and realizing digitization. Once the offline database is established, the online algorithm can be moved over to analyze the consumer's offline shopping behavior and recommend products that consumers like, like Amazon.
We hope to use the online database to depict the appearance of new users, especially consumers who use Wi-Fi in the mall for the first time. We know almost nothing about them, and once we use a mobile phone number to connect to the database, we can get the consumer ’s past shopping behaviors in online stores, so we can use the database to recommend their favorite products.
Wi-Fi's location feature personalizes shopping. When a consumer walks into the mall, his walking path will be recorded one by one, including the length of time he stays in a store. After the data is analyzed and processed in the background, the mall can push a dedicated mall line for consumers. For shopping malls, they can also lock down the most popular shops and make more reasonable brand combinations.
The mall's wireless network coverage project is to ensure that employees and customers in the mall can use mobile terminals (mobile phones, tablets, etc.) to access the network anytime and anywhere after simple and quick authentication, and to achieve wireless positioning of customers in the mall, and For the collection and unified management of customer information, further fine-grained marketing information is pushed for different customers; at the same time, in order to expand the possible wireless office system of the mall in the future, the wireless network must have certain security, manageability, and scalability Sex.
This wireless construction includes the following requirements:
1. Achieve public area coverage
This wireless network provides wireless network access services for employees and customers in the shopping mall. The coverage area includes all public areas in the shopping mall to ensure that users can have a better wireless experience in all areas of the shopping mall.
2. Network security
In order to keep customers in the mall more, the mall hopes to provide customers with wireless Internet access services, while collecting customer identity information, so that the mall can carry out further targeted marketing. Since wireless networks can be accessed anytime and anywhere, if employees and customers in the mall use internal wireless networks, they must have corresponding encryption and authentication mechanisms to ensure network security. On the premise of meeting Order 82 of the Ministry of Public Security, a fast and convenient short message authentication system is provided to facilitate customers to access the Internet. At the same time, unified behavior audit and management are performed for authenticated customers to ensure network security.
3. Wireless positioning requirements
Based on wireless network, third-party positioning software can be used to wirelessly locate customers in the mall. At the same time, based on advanced wireless positioning technology, the mall can expand a variety of wifi applications, including wireless passenger flow statistics, mall vector digital maps and real-time navigation of mobile phones. New wireless marketing methods in the era of big data, such as information push platforms in geographic areas and car parking applications.
H3C's wireless retail solution provides industry-leading wireless network applications for shopping malls by combining H3C's WLAN product line, iMC business software products, and customized shopping mall business component products. Including, shopping mall customers wireless Internet access, wireless positioning, wireless WLAN-based marketing information presentation, location-based marketing SMS push and so on. Provide customized solutions for department stores, shopping malls, and mall customers that are close to marketing.
Now more and more shopping malls begin to provide customers with wireless Internet access services. Wireless networks provide customers with business environment and leisure Internet access services, which reflects the importance the mall attaches to the customer experience, and it is easier to reflect the grade and attract high-value customers. Customers stay longer in the mall, increasing stickiness. However, the openness of wireless networks to customers has also brought a series of management difficulties to the reliability and security of the mall's own network.
82 号令规定，为加强和规范互联网安全技术防范工作，保障互联网网络安全和信息安全，促进互联网健康、有序发展，维护国家安全、社会秩序和公共利益，在公共场所提供上网服务，必须记录并留存用户登录和退出时间、主叫号码、账号、互联网地址或域名、系统维护日志的技术措施。 Order 82 of the Ministry of Public Security stipulates that in order to strengthen and regulate Internet security technology prevention work, guarantee Internet network security and information security, promote the healthy and orderly development of the Internet, maintain national security, social order, and public interests, it is necessary to provide Internet access services in public places. Record and retain user login and logout times, calling numbers, account numbers, Internet addresses or domain names, and technical measures for system maintenance logs. This also puts new requirements on the network of our shopping mall. Today, mobile terminals are widely used, and it is very convenient to send account numbers and passwords to users through mobile phone text messages. E-mail 通知相比，短信通知更快捷，也能以此方式获知用户的手机号，确定初步身份信息。 Compared with E-mail notifications, SMS notifications are faster, and users' mobile phone numbers can be obtained in this way to determine preliminary identity information.
As a shopping mall access layer network, wireless network maintenance workload is large, coupled with the flexibility and invisibility of the wireless network, the management requirements for the wireless network are also stronger than the wired network. The wireless network directly faces the end user, and has high requirements for the stability, real-time and effectiveness of the management system, and puts forward higher requirements for the network of the shopping mall.
The wireless network project of the mall has strict requirements on security. It must be able to authenticate the identity of outsiders. On the one hand, it protects the network security of the mall to a certain extent. On the other hand, it ensures the normal use of the network and improves the efficiency of the network and the user ’s Use experience. According to the characteristics of the shopping mall, this scheme recommends the use of a portal SMS authentication scheme. Customers can obtain the login password through SMS. The login account is the user's mobile phone number. This authentication method can reduce the workload of the mall's network management personnel, and record the login information of the wireless access users, which is convenient for future review.
Aiming at the characteristics of mall customers with high fluidity and numerous and unstable customers, a single server of the H3C wireless guest access management module (UAM) can support up to 10,000 people, and the number of registered guest accounts can reach 100,000. After the mobile phone is connected, the background server will quickly open an account for the new customer, and send the login password to the customer's mobile phone. After the visitor is successfully authenticated, the access range is controlled by ACL and VLAN according to the visitor policy. Automatically delete invalid guest accounts on a regular basis to ensure smooth access for subsequent customers. If it is detected that the access user's mobile phone is in a “no traffic” state for a long time, the UAM server can process the user offline. When the user accesses again, there is no need to enter the mobile phone number and password again, and the “fast and non-sensing” access can continue. Go online.
After the certification is completed, the page will go to the marketing page of the mall (H3C supports customizing the interface according to the template and can provide ready-made templates to independently design the marketing interface of the mall). At the same time, H3CUAM components will also provide external interfaces to support interfacing with third parties for convenience The mall or a third-party manufacturer reads UAM's daily new registered user information and imports it into the mall database. At the same time, it supports importing mall general members or VIP customer information from the mall database into UAM.

用户行为审计组件日志审计界面如下图： UBA user behavior audit component log audit interface is as follows:
Due to the large number of APs involved in the mall, it is recommended to use the Fit AP solution to manage APs in a unified manner using wireless controllers. The FIT AP networking solution can be used for intelligent radio frequency management. When one AP fails, other APs around it will automatically adjust the power and re-cover the signal in this area to ensure good signal coverage. When an illegal AP enters the wireless network and causes signal interference, the H3C intelligent radio frequency management system can locate the AP's location so that it can be eliminated in time.
When using WLC + FIT AP, the AP will automatically obtain an IP address through DHCP after it is started and automatically search for an associated WLC. After the CAPWAP tunnel is established with the WLC, it will automatically download a configuration file from the WLC. And update software versions.
The biggest advantage of FIT AP networking is that the AP itself has zero configuration. After the AP is powered on, it automatically downloads software versions and configuration files from the wireless controller. At the same time, the wireless controller automatically adjusts the working channel and transmit power of the AP. In addition, the RF scan of the wireless controller to detect Rouge APs in hotspots can eliminate interference from other APs in time to ensure the stable operation of the APs. In terms of network management, the network manager can achieve the effect of controlling the AP by only managing the wireless controller device, which greatly reduces the workload of the wireless network's later maintenance and management.
In order to facilitate unified management and improve the security of the equipment, the wireless power supply design of the shopping mall is recommended to use POE power to remotely power wireless APs. The POE method is used to supply power to the AP through a network cable. The POE power supply method has the following advantages: First, the security is higher. The power supply through the network cable can avoid the use of local power, effectively reduce the deployment of strong power, and improve the safety of power consumption in the building. In addition, the power supply management of the AP can be achieved through POE power supply, and the H3CWSM wireless operation and maintenance management software can be configured to realize the AP's timing switch, on the one hand, to improve the security of the wireless network (the wireless network can be turned off when not needed), , Can also save the daily expenses of the mall (when not necessary, turn off the AP to save electricity).
3. Wireless positioning solution
Personalize shopping with wifi-based wireless positioning. When consumers enter the mall and connect to the mall's wifi, the mall can quickly learn the user's movements in the mall, so as to collect all the information of the users in the mall. After the data is analyzed and processed in the background, the mall will be able to provide consumers with customized shopping information tailored to the mall. For shopping malls, they can also lock down the most popular shops and make more reasonable brand combinations.
According to the business needs of the mall, the positioning business can be divided into three categories:
(1) Statistical analysis of location data to obtain consumer behavior habits. This service is a non-real-time service. The requirement for positioning accuracy is to be able to determine whether to arrive at the store. The size of the store is different. The higher the positioning accuracy, the more determined the store is. The better the accuracy.
(2) Geographical area of location data, which pushes consumers based on location-based advertising. This service has certain real-time requirements, and the real-time requirements are not high.
(3) Location-based positioning and navigation services provide consumers with real-time navigation services. This service requires high real-time performance and positioning accuracy.
The Wi-Fi positioning platform solution based on the network side can meet the needs of the first and second types of services above, and can basically meet the third type of services. The best solution for the third type of services is the mobile phone real-time navigation engine solution.
Wi-Fi 定位平台跟 AP/AC 设备对接，网络侧位产品常用于用户群体性行为进行分析统计和 Wi-Fi 终端设备的定位。 Based on the connection of the Wi-Fi positioning platform on the network side to AP / AC devices, network side products are often used for user group behavior analysis and statistics and Wi-Fi terminal device positioning.
