Private Economy News--New Business Opportunities Hidden in 3D Live Map, an "Egg" Laid by LED Lighting發布時間:
       When more and more shopping centre cover over 100000 square meters, they are faced with the situation of insufficient monitoring, hence people are looking for indoor LBS tech that more rational and more closing to the trend of future development.

       Faced with the situation of frequently bias of WIFI, Bluetooth etc indoor positioning system, rapid popularization let LED visible light communication tech be a new and expected Indoor LBS tech, solve the problem of accuracy below 5 meter, first limit the positioning accuracy below 1 meter.

       Up till now, tech pioneer of domestic or international tech pioneers all focus on LED-LBS tech, but a Zhuhai company first turned LED-LBS tech from lab into commercialization. On 28th day of June, “E-Guang” APP Product based on LED VISIBLE LIGHT COMMUNICATION U-beacon system which developed by Great Aim Optical Communication Technology Company (“GAOC”) with dozens of domestic and international patents is going on trial operation and enter internal test in Changzhou. With no doubt, “E-Guang” becomes the first LBS tech that implements business application and indoor 3D visible map in the world.


       Begin from a LED lamp


       Whatever GPS or WIFI, or Bluetooth, it is obvious of the defeats on accuracy. The accuracy of positioning is 10-100 meter, affected by environment, accomplish by more matched data and relatively slow reaction.


       Currently, the WIFI and Bluetooth tech is relatively mature. Rely on the principle of signal attenuation in the air of phones and WIFI, through testing the tense of wireless signal, calculate the attenuation distance to determine the indoor location. But, due to wireless attenuation in the air easy affected by internal building environment, the signal is not accurate. It’s hard to locate below 5 meter, and also hard to ensure the signal stability and transmission confidentiality.


      Although many international universities、 institutions、 Google、 Nokia、 Motorola and Microsoft engaged in such research, but still in theory. When faced with “last 1 kilo indoor GPS , Traditional outdoor GPS cannot reach the accuracy.

       But early 21 century, many technical exports have other possibility- a new environmental, energy-saving lighting material-LED. Experts use the high speed light flashing signal by fluorescent light or light emitting diode to transmit information and locate, the accuracy reach 1meter.

       This totally overwhelm the realization of lighting, then, global experts focus on how to use lights from LED to make cycle of information transmission to information receive. Eventually, people find solution from smart phone.

      Tang, Haijun, vice manger of GAOC Company introduce that the camera of smart phone can be work as the terminal of information receiving. This tech is not only the revolution of digital lighting but also a solution of Indoor location.

       The theory of tech is that the emitted information is compiled into a modulated signal, and attached to the LED driving power supply with the method of broadband modulation. Using indoor light as subject of transmission, when shoppers enter into lighting area, receive light signal by smart phone and decode specific ID code. Using ID information, we can match such information on database to locate.

      From the view of exports, this tech almost resolves the defeats of indoor location: accuracy positioning below 1 meter, stability of signal, confidentiality of information, not easy affected by environment.  

      Chinese Companies first try to commercial application

       Whatever Japan, Korean, USA or China, all engaged in the research of LED Visible Light Communication. One company named “Bytelight” founded in 2011 was attracted more and more attention in such field. From the beginning development to financing, Bytelight have right now cooperated with lighting company, and prompt into product producing. Relatively, Chinese companies begin much later.

       As a cooperation project with State Key Laboratory of Solid State Lighting, LED-LBS U-beacon system developed by GAOC make up for the interference of surrounding light in the aspect of visible light reception. U-beacon system use CMOS camera instead of LED to receive light signal. And in the middle of this year, commercial application “E-Guang” App with 3D visible map was on line, and already been into trial operation in Changzhou.


       Miss Wu, the secretary general of China Solid State of Lighting Alliance (“CSA”) indicated that LBS has a promising future. On her view, U-beacon system indicated the way of LED future development not only from its technology but business operation as well. Meanwhile, she also suggests that LED industry no doubt will be showed a leap development in future ten year whatever on Policy or Market perspective. Companies owed technical should build an opening platform to all LED suppliers with the stand of opening-up attitude. 

      Mr Tang, vice manager of GAOC introduced that we developed U-beacon system and “E-Guang” is one of APP products applied in business field. It implicated in many events such as shopping mall, supermarkets. It has some functions as navigation, shopping guide, searching, game, social chat etc and helps whole shopping mall to be an O2O platform.

       We said, when people get shopping, they can inquire local life info at any time by phone and PAD, easy to change floor plan, get services like LBS, visible map, navigation, emergency assess , restaurants, cinemas, Toilets, and discount of brands etc. Furthermore, based on this App, it derives more other applications like group-buying, internet comments and social chat.

       In fact, on 23th day of May, “E-Guang” was going on trial operation in shopping centre in Changzhou. Afterwards, our technical team updated the version of product to apply in such big business projects. Until now it can modify 3D indoor map and 360 view of panorama. At same time, in the day of testing, we put some games like “Harvester“ on line, shoppers can enjoy the game when they are wandering in the shopping centre.

       Explore the blueprint of Visible Light Communication

       On the view of Tang Haijun, tech application is now under primary level. Compared with WIFI and Bluetooth, VLC Tech has advantage of low cost of equipment and maintenance, accuracy of location, does not need to scan signal like WIFI and Bluetooth. VLC Tech has a promising future.

       According to the report, up till to Jan of 2014, mobile internet user amount for 8.38 million, 67.8% among which are mobile phone user. Mobile internet user amount for 5 billion, occupy 80% of total internet user, keep the first internet user position for long. Now our mobile internet is used by all people in country.

      At meanwhile, in China, LED has become the development trend of future lighting. According to survey, many executives of company and industry experts consider that 2013-2015 is the rapid growth period of LED lighting. And in 2015 the popularization of LED will be over 50%.

      “Currently the project of exchanging the power of LED is undergoing in many shopping mall. U-beacon Tech only added a low cost spare part on power, and promote with the overwhelming trend of LED exchanging.” Tang Haijun, vice manger of GAOC consider that in business field, the function of Visible Light Communication is outstanding, additional combine with smart phone and internet, through 3D visible map, VLC tech will promote the construction of O2O platform in business field. Hence, they are looking for business cooperation in big city of China. 

       LED light and smart phone are two necessary hardware of Visible Light Communication, and which to some extent provide more possibilities of development of LED-LBS. On the view of technical experts and operation experts, this tech has a glorious promising not only in business field but also in other industries in near future. 

       Now the mature type of VLC Tech is underground positioning tech and specific industry positioning tech. Both of them could through accuracy, stability and convenience of light positioning to confirm the location information, to control security and predict disaster. At same time, one point to one point transmission of VLC tech also applied in such specific industry.

       Of course, more imagination: Maybe one day, Visible Light Communication Tech is applied not only indoor, but outdoor as well by the popularization of LED.

       Perhaps not only WIFI we now use commonly but also various screens outdoor all could highly digital applied .
