Reporter: What is the current situation in the lighting industry? What are the characteristics of competition?
Wu Changjiang: In the lighting industry, the technical content is not high at the start, and the threshold is low. Strictly speaking, the industry is still in a disorderly state. In recent years, according to authoritative statistics, it is growing at more than 20%, with tens of thousands of companies. Regardless of the market law or the current changes in the competitive landscape, I believe that the next step of integration is inevitable.
Reporter: Now the price of raw materials has risen, which has an impact on many industries, especially processing enterprises. Does it have a big impact on the lighting industry?
Wu Changjiang: I admire one point of view: mediocrity people encounter difficulties and detours, smart people encounter difficulties and find ways to overcome them. A few years ago, the gross profit of our industry was above 40%, which is a profitable industry. The impact you mentioned is actually a return to value for a large-scale, branded company. The choice of the market is to lead our leading companies to lead the industry to maturity in advance.
Reporter: NVC should be a leading company in the industry. What kind of mentality is this integration or opportunity? What are the measures? In which direction will this industry develop?
Wu Changjiang: Enterprises are facing the world, and the industry is facing differentiation. It is the trend. For example, we have to take the road of internationalization now. We hope to have a model in China. After the model is refined, it will be piloted overseas. We have started in Southeast Asia and are playing our own brand.
There is also a large foreign enterprise to do the processing, you have to know where your cost performance, there is core competitiveness to produce cost-effective. Now NVC has set up its own R&D center in Shanghai, investing tens of millions of yuan every year. R&D allows us to know where we are, and this is a shift. In this way, we have an international perspective, and we can truly connect with the international community. We are now helping GE to process. In addition, we acquired a sales company in the UK and tried to find a breakthrough in the international market using a foreign ready-made network. I feel that internationalization is not for the label, but it should be real.
Now, the domestic market is growing, and the differentiation of the industry will also emerge. The more the scale effect is not done, the harder it is to do it. In such a differentiation, the industry will become healthier and the industry is actually such a trend.
Reporter: As a leading company in the industry, will there be pressure? You are the vice chairman of the Guangdong Lighting Association and the president of the Huizhou Lighting Association. What kind of work will you do for the development of the industry?
Wu Changjiang: When you are big, you have to take responsibility and lead the industry to do things. This is also a contribution to society and a contribution to the industry. It is necessary to standardize, develop and grow with this industry, and we hope that our efforts can play a good role.
What is a wireless AC controller? What does it do?
Wireless AC controller is a kind of network device, such as the AC100/150 of Fengrunda, which can be used to centrally control and manage wireless aps. It is the core of a wireless network and is responsible for managing all wireless aps in the wireless network. AP management includes: delivering configuration, modifying related configuration parameters, RF intelligent management, and access security control.
Why use a wireless controller, and what exactly does it do?
In fact, the role of the wireless controller is to play a gateway function between the WLAN and the Internet (on the router), and the data from different access points are aggregated and accessed to the Internet. The role of an access point (AP) is to complete wireless access, and it can control user access through network flags.
The role of wireless controllers
1, Flexible networking mode and excellent scalability
The AP does not need to be directly connected to the AC, so that the AP can be deployed in any place that needs to be covered through the network, such as you deploy an AP in each employee's home, and then connect to the wireless controller inside the enterprise through the VPN, you can expand the wireless network of the enterprise to the family of each enterprise member.
2, intelligent RF management functions, automatic deployment and fault recovery
Through the dedicated RF management module, we can initially estimate the AP deployment according to the user's architectural design drawing, and can calculate the average bandwidth of the wireless terminal, the coverage between AP and AP in the actual debugging process.
3. Centralized network management
All the configuration of the wireless network can be completed by configuring the wireless controller. For example, enable, manage, and maintain all AP devices and mobile terminals, including all functions such as radio wave spectrum, wireless security, access authentication, mobile roaming, and access users.
4, powerful roaming function support
The wireless controller uses AP as the boundary combined with fast RF management system, which greatly reduces the connection time between wireless client and AP, and thus realizes the function of fast roaming.
5. Load balancing
AP and wireless controller systems can distribute wireless users or terminals to nearby aps within the coverage area of an AP, ensuring the number of each wireless terminal or the sum of AP bandwidth transmission or the upper limit of each wireless terminal bandwidth.
6, wireless terminal positioning, rapid fault location and intrusion detection
Wireless controllers can track and locate the location of wireless terminals, such as wirelessly connected computers, PDAs and Wi-Fi mobile phones.
7, powerful access and security policy control
At present, the wireless system supports authentication of 802.1, WEB authentication, MAC, SSID, VPN, etc., and supports various encryption modes such as WEP, WPA, WPA-PSK, WPA2, etc., and all configurations can be configured globally through the wireless controller.
8, Qos support
AP and wireless switching systems can limit the maximum bandwidth of a user's wireless connection within each user's privileges. For different IP services, the system can also define different QoS queues through the wireless switch module. For example, for wireless voice applications, SIP and RTP protocols can be set in the high queue, while common applications such as http and ftp can be set in the low queue.
The wireless controller AC is more advanced than the AP, plays the role of manager in the wireless network, and the wireless controller AC also acts as a client to complete a series of functions in the wired network (such as authentication, authentication, etc.). However, wireless controller AC is not a WLAN device specified in the 802.11 protocol family, but as a supplement to the protocol in specific applications, and its price far exceeds that of ordinary access point (AP) devices.
In small-scale wireless networks that use only a few aps, it is not economical to use expensive wireless controller AC equipment. However, if the number of wireless aps is large, more than 20 can be used AC controller.
