The LGD Guangzhou project can be described as twists and turns. As early as 2009, LGD reached a principled agreement with the Guangzhou government. In March 2010, LGD, Guangzhou Kaide and Guangzhou Skyworth under the Guangzhou Economic and Technological Development Zone signed a joint venture to set up a joint venture with a total investment of 4 billion US dollars. It mainly produces 8.5-generation LCD panels, and plans to produce 60,000 units after the first phase of production. The film/month will then be expanded to 120,000 pieces/month. The project received approval from the National Development and Reform Commission at the end of 2010.
However, due to changes in the LCD panel industry environment, panel prices and demand have been in a downturn for a long period of one and a half years. Faced with relatively large difficulties, coupled with the emergence of new technologies and new products, LGD has repeatedly postponed the project. The date of commencement, but Li Bangyu, senior vice president of LGD Business Support Center, repeatedly stressed in an interview that “the principle of LGD has not changed, and the project should be launched and ultimately successfulâ€.
The timetable for repeated revisions finally has a certain content. According to Skyworth Digital's announcement, LGD and Skyworth Digital will establish a joint venture company, Lejin Display (China), which mainly produces and sells TFT-LCD materials and other electronic components, and conducts import and export and after-sales services for such products. The parties are expected to determine the details of the relevant investment and update schedule at the end of June.
The reporter learned from LGD that the Guangzhou project, which was laid on May 22, will still be the 8.5 generation line. As for other specific information such as the amount of investment, the person of LGD said that it is communicating with the Korean headquarters, and there is no publicly available. Accurate information. According to the previous plan, the registered capital of the project is 1.334 billion US dollars, and the investment ratios of LGD, Guangzhou Kaide and Skyworth Digital are 70%, 20% and 10% respectively.
The industry believes that this time the LGD Guangzhou project has entered a stage of substantial advancement, in addition to the impact of panel tariff increases, it is also related to the rebound trend of the LCD panel industry. In addition, this year's major global sports events such as the London Olympics will drive color TV sales, color TV manufacturers will increase inventory before the start of the event, and the purchase volume of LCD panels will also increase.
The data showed that panel prices rose slightly in April, and the price of 32-42-inch panels rose by $1-3. The industry believes that this has promoted the process of restarting the construction of factories in China by foreign panel companies. It is reported that not only the LGD Guangzhou project, but also the high-generation line of Samsung in Suzhou will be restarted.
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.
