LiFi market hides opportunities LED lights do network effort without effort

LiFi (LightFidelity), a branch of visible light communication technology, is regarded by the LED manufacturer Qinshang Optoelectronics as "Bai Fumei" combined with LED "Gao Fu Shuai". By implanting the chip in the LED light, the LED light turns into a wireless hotspot, an alternative "WiFi" - it also features ultra-high speed, secure communication, and precise positioning that WiFi does not have.

However, WiFi vendors don't have to be too nervous, and everything is just beginning.

Indoor information network fusion agent?

Optical communication is not new. People have become accustomed to transmitting optical signals on fixed-line optical fibers to achieve high-speed Internet access. In the field of mobile communications, it has also experienced multiple iterations of 2G, 3G, and 4G. Visible light communication (VLC) is not fundamentally different from it. The essence of light is wave. VLC uses a wider frequency of visible light to transmit signals. However, the communications industry is increasingly plagued by limited spectrum resources, and every upgrade iteration does not circumvent the discussion of how to allocate new spectrum. The visible light spectrum is at least 10,000 times wider than the radio spectrum and has not been exploited.

LiFi technology was originally created to solve the problem of visible spectrum utilization. By combining high-frequency switch LED lights and communication technology, scientists created LED-LiFi lamps similar to the Morse code, and formed a viable VLC communication loop by mounting corresponding receiving and transmitting devices on the terminal equipment.

"By implanting chips in LED lights, turning LED lights into a wireless hotspot, using fast optical pulses, wireless transmission, binary coding to achieve communication purposes, this new technology to replace electromagnetic waves with LED visible light, It is called LiFi." The introduction of Qinshang Optoelectronics shows.

Bell, the founder of communication technology and inventor of the telegraph, had envisioned using visible light as a medium to communicate. However, the technology at the time could neither produce a useful optical carrier nor transmit light from one place to another. The LED lamp has a high modulation rate, the human eye does not feel the flicker of light, and with the new technology, the LED lamp can already transmit data to 5 meters away, and LiFi is feasible.

Compared with WiFi, LiFi lamps can now reach 10Gbps data transmission rate (100 times of 4G rate), and visible light can not cross walls, and home Internet access will become more secure. In the field of precise positioning, LiFi also shows advantages. Supporters believe that LiFi technology has the basis to replace WiFi. However, some people think that although the substitution effect of LiFi exists, there are certain limitations in using visible light as a communication carrier. In the future, LiFi may coexist with WiFi and be used in smart cities.

"I believe that visible light communication will become a fusion agent for future indoor information networks. It will not only provide valuable spectrum resources for triple play or even N-network convergence, but also make this technology convenient, broadband, green, energy-saving, and safe. To the extreme,” said Jiang Jiangxing, a proponent of the three-network integration program and academician of the Chinese Academy of Engineering.

Yan Jiangxing believes that VLC will play a powerful role in upgrading traditional industries, stimulating emerging industries, transforming business models and prospering service industries. “It will be a strategic emerging industry with trillions of output value.”

As a mobile advertising display, Vehicle LED Display has precise advertising positioning and is widely used in public transport, taxis, case trains and family cars. It is widely used in outdoor image advertisement, information publication, activity advertisement, mobile background stage, information media and live broadcast of events, etc. its products are effective and flexible and widely used.

Features of Vehicle Led Display:

1. There is a unified operation background. Through GPS, you can know the specific location of each on-board screen. GPRS wireless replacement product content can play all the specified content partially. The above operations can be realized by computer and mobile phone

2. Mobile advertising has stronger communication and better effect. For vehicle mounted display screen, it has been in a state of motion, and advertising information has been more widely spread, with stronger communication ability and larger coverage area than fixed platform.

3. Vehicle Led Display adopts high brightness LED lamp beads, which can be seen clearly in the sun. The product has UV resistance in the sun, and the protection level reaches IP65, which is suitable for all-weather playback.

4. Ultra thin design of the product, allowing disassembly and assembly, reducing the space occupied in the car

5. Product module design, reliable and stable performance, power supply, system card, separate device, more stable product, more convenient maintenance

6. Led vehicle screen with GPS function can accurately know the screen position and operation status, including vehicle speed, driving direction, alarm status, etc.

7. Vehicle LED Display add brick and tile to the bright urban environment and become a beautiful scenic spot.

Original title of structure:

1. The screen adopts wide voltage, which can be applied to any vehicle in any occasion.

2. Single box design, according to customer requirements, can be iron box, can be aluminum box.

3. The system adopts group network function, which can control all vehicle screens individually. Even if the screen body is not in the same city, it can send specified and information through GPRS.

4. The screen body has an understanding of the lifting device, and the height can be adjusted according to the customer's requirements.
