Create LED finished products professional store
Although the ancient town has a large number of LED enterprises, and the supporting industrial chain is also very perfect, but the entire ancient town has not really called the professional store of LED products, Times Light Plaza, Yusheng Lighting Plaza, Yinquan Lighting Plaza, etc. are traditional lighting lighting There are very few LED stores, and there are one or two LED stores in the ancient town, but they do not have the scale and grade, and they are not located in the professional finished product trading market. Since the Lei's LED International Purchasing Center is positioned in the finished product specialty store, companies or businesses that do accessories are not considered for absorption.
From the development process of the circulation pattern of the ancient town store, more and more professional stores will be born in the future, such as commercial lighting and home lighting, which will form a classification in the future, and a professional store will be created. The street shop will suffer. The greater the pressure of survival, the bleak business, the future of the ancient town market will be fully upgraded to a professional store, to the direction and development of professional stores. If some hypermarkets are greedy, they may not meet the requirements of customers, and it is more convenient and convenient to go to professional stores.
Ray's LED Purchasing Center to create LED finished products professional store hopes to provide a development idea for the ancient town store format, which can promote the development of the ancient town lighting industry.
LED industry upgrades on the road
From the current point of view, the entire industrial chain of Guzhen is undergoing transformation and upgrading. Although the LED industry itself is shuffling, after the end of this process, the industry will move towards a healthy growth stage, and then the market will show a spurt of growth.
From the perspective of enterprises, more and more lighting companies are beginning to change their development direction and enter the LED industry. In the future, there will be more lighting fixtures using LED light sources. This is the law of the development of the lighting industry, but also the trend. The earliest domestic use of incandescent lamps, and later began to use energy-saving lamps, now incandescent lamps have been eliminated, and the energy-saving lamps market has been squeezed by LEDs smaller and smaller. This also shows that LED lighting fixtures have a lot of room for market growth.
At present, one of the problems of LED is that the degree of recognition is not enough, and the consumer groups are generally still unacceptable. The reasons are: First, the government's promotion is not big enough, although the state has introduced some promotion policies and given certain financial subsidies, But this is still a drop in the LED industry; Second, consumers believe that the price of LED lighting products is high, third, the technical bottleneck is large, although the gap between domestic technology and foreign countries is shrinking, but there are still many problems in the application of LED technology. Many domestic enterprises rely mainly on foreign companies for their core technologies. Fourth, the channel is single, LED walking engineering channel is only a process, because at present the government is promoting, the government requires energy-saving emission reduction and environmental protection, and develops a low-carbon economy, so it is necessary to replace the metal halide lamp. If LED lighting fixtures enter the common households through retail channels or other channel modes, and drive the entire third-tier market to be active, then its market capacity is difficult to estimate. Because the third-tier market is the largest market.
LED shuffle will not be like the home appliance industry, and finally there are a few giants, because the current LED technology content is very low, the industry may set a benchmark in the industry after shuffling, in addition, the LED threshold is also very low, unlike home appliances There are many technical bottlenecks in the industry. In short, there will be a market if there is demand.
Domestic communication, 4 g module in addition to support two kinds of LTE FDD LTE/TD - LTE standard, also compatible with 2 g / 3 g down, support td-scdma/WCDMA/EDGE/GP/GSM/CDMA1X/EVDO mode. The data service downstream rate can reach up to 100Mbps, the uplink rate can reach up to 50Mbps, providing customers with high-speed Internet access and wireless data connection and other functions. In addition to providing high-speed data access, it also provides voice, SMS, communication book and other functions, which can be widely used in notebook, tablet, touch screen communication devices, smart phones, video surveillance, multimedia mobile phones and vehicle equipment and other terminal products and vertical applications. Today, I will introduce you to what is 4G module and how to use 4G module.
What is 4G module
4G module said TD-LTE and FDD-LTE and other LTE network standards are collectively referred to. It has the characteristics of fast communication speed, wide network spectrum and flexible communication. 4G module refers to a product whose hardware is loaded to the specified frequency band, software supports the standard LTE protocol, and software and hardware are highly integrated and modular. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Second, how to use 4G module
The 4G module is usually inserted into the circuit board or the patch module is welded to the circuit board, and the corresponding SIM card is inserted, and the network is connected through the 4G cellular network. In the common transparent transmission mode, data can be directly sent to the target server through the 4G module, and the 4G module can receive data from the server at the same time, and send the data to the serial port, which is received by the serial port device connected to the 4G module. Users do not need to pay special attention to the data conversion process between serial port data and network data packets, only need to insert the module to the target position, simple connection and parameter setting, you can achieve transparent transmission between the serial port and the network end.
What is the 4G module How does the 4G module work
4G module, also known as 4G transmission module, 4G communication module, 4G LTE module. It is a kind of hardware loaded to the specified frequency band, the software supports the standard LTE protocol, and the software and hardware are highly integrated modular products, with good compatibility, fast communication speed, large amount of communication data, wide network spectrum, communication flexibility and other characteristics, widely used in electric power, environmental protection, finance, industrial automation and other fields.
The working principle of 4G module
It has the characteristics of fast communication speed, wide network spectrum and flexible communication. The hardware integrates radio frequency and baseband on a small PCB board to complete wireless receiving, transmitting and baseband signal processing functions. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
Through high-speed networking, the 4G module transmits all terminal business data and equipment operating status to the business center in real time. Through the management monitoring platform, the terminal equipment operating status can be monitored in real time and equipment faults can be timely checked. The efficiency has been greatly improved in many aspects such as operating cost, operation scale and service timeliness. Suitable for shared massage chair, public charging pile, vending machine, vehicle system, environmental monitoring, power remote monitoring and other industries.

Good compatibility
4G module supports FDD LTE/TD-LTE two LTE standards, can also be backward compatible with 2G/3G, support LTE-FDD, LET-TDD, WCDMA, TD-SCDMA, CDMA, GSM and other bands.
Large amount of communication data
4G module downstream rate can reach up to 150Mbps, uplink rate can reach up to 50Mbps, to provide customers with high-speed Internet access and wireless data connection and other functions, suitable for large data transmission applications, such as: remote video surveillance.
High communication speed
The 4G module has a lower ping value than the 2G/3G module, and it takes less time for the module to send data packets to receive the response from the server, which is suitable for applications requiring high response speed, such as remote alarm.
