In the first half of this year, the "butterfly effect" of a series of global economic weaknesses such as the European debt crisis has pushed the already dangerous LED industry to the forefront. The packaging industry in the middle of the industrial chain is also difficult to escape.
Since the beginning of August, LED listed companies have released their first-half financial results for 2012. The growth rate of revenue and gross margin performance are not optimistic. For many domestic small and medium-sized LED packaging companies, they are also caught in tight orders and negative growth in profits.
At the same time, according to the report of the High-tech LED Industry Research Institute (GLII), the price of domestic white LED lamp beads has dropped by 20% in the first half of this year. The rapid decline in the price of packaged devices means re-integration and cost reduction for medium and large package companies; for small businesses, it means meager profit and life.
“Since last year, the profit of packaging devices for display screens has fallen to the bottom.†Xiao Wenyu, general manager of Amp Optoelectronics, has deep feelings about the current state of the industry chain. Display companies cannot reduce costs from packaging, and packaging companies cannot Cost savings in common raw materials, processes, and management.
In such an industry filled with the taste of life and death, how to quickly get rid of the predicament, survive this period and survive, become the biggest trouble for the current packaging companies. On August 17, at the 9th Industrial Theme Summit held by Gaogong LED, Wang Peng, the sales director of Baishi Optoelectronics, said frankly: "Whoever has deep pockets and strong financial strength, whoever can safely pass the reshuffle period. â€
In fact, for a long time to come, it is not only funds that determine the “life and death†of LED packaging companies, but also factors such as cost control and industrial chain integration efficiency.
Increment does not increase profits
As of press time, the LED packaging listed company has announced the financial report for the first half of 2012. The financial report shows that these companies have experienced different levels of performance decline.
Among them, Hongli Optoelectronics (300219) realized operating income of 257 million yuan, down 5.69% over the same period of last year; net profit was 33.22 million yuan, down 11.65% over the same period of the previous year; Guoxing Optoelectronics (002449) realized operating income of 446 million yuan Compared with the same period of the previous year, the net profit was 18.25%, and the net profit was 42.09 million, which was 27.52% lower than the same period of the previous year. While Ruifeng Optoelectronics (300241) achieved 21.97% growth in revenue, the net profit still dropped by 3.02%.
The sharp decline in the price of LED packaging is the main reason for the loss of many packaging companies.
According to the GLII report, in the first half of this year, the price of display devices has fallen to a low level in the three major packaging markets. The products have no profit at all; the price of backlight devices has dropped by 15%, but the market has entered the supply chain due to the relatively closed market. The packaging companies can still guarantee a certain level of profitability; while the price of lighting devices has dropped by 10%-20%. 
Outdoor CPE is commonly used to provide broadband access services, especially in remote areas or places without traditional wired network coverage. It can transmit an Internet connection via wireless signals to the building or area where the user is located. Outdoor CPE is typically a highly protected and durable device designed to handle harsh weather conditions in an outdoor environment.
Outdoor Cpes typically include the following main components:
1. Antenna: Outdoor CPE is usually equipped with a high-gain antenna for receiving and sending wireless signals. These antennas can be designed for different frequency bands and wireless standards.
2. Wireless module: Outdoor CPE usually includes a wireless module to handle the transmission and reception of wireless signals. This module usually supports different wireless standards such as Wi-Fi, LTE, 4G, etc.
3. Router function: Outdoor CPE usually has the function of a router, which can distribute the Internet connection to the device where the user is. It can provide IP address allocation, port forwarding, network security and other functions in the local area network.
4. Power supply and battery: Since Outdoor CPE is usually used in outdoor environments, it usually requires a reliable power supply. Some Outdoor Cpes are also equipped with batteries to provide continuous Internet connectivity in the event of a power outage.
The main features and advantages of Outdoor CPE are as follows:
1. High-speed broadband access: Outdoor CPE can provide high-speed broadband access services through wireless signals, so that users can enjoy high-speed Internet connections in places without traditional wired network coverage.
2. Flexibility: Since Outdoor CPE is a wireless connection, it can be used in different locations and environments. Users can place the Outdoor CPE in the best position as needed for optimal signal coverage and performance.
3. Simple installation: Outdoor CPE usually has a simple installation process, and users only need to place the device outdoors and make some basic Settings to start using the Internet connection.
4. Strong anti-interference ability: Outdoor CPE usually has strong anti-interference ability and can provide stable Internet connection under harsh environmental conditions. It can cope with various sources of interference, such as electromagnetic interference, weather conditions and so on.
5. High reliability: Outdoor CPE usually has a high degree of reliability and durability, and can be operated for a long time in a variety of outdoor environments. It usually has waterproof, dustproof, lightning-proof and other functions to cope with different weather conditions.
Outdoor CPE is widely used in a variety of scenarios, especially in rural areas, mountains, islands and other places without traditional cable network coverage. It can provide high-speed broadband access services to residents and enterprises in these areas, helping them to enjoy the convenience of the Internet.
In summary, the Outdoor CPE is a client device for outdoor environments to provide high-speed broadband access services via wireless signals. It is highly reliable, flexible and anti-jamming, and can provide a stable Internet connection in a variety of outdoor environments. It plays an important role in providing broadband access services, especially in places without traditional wired network coverage.
