It is understood that most of PureLiFi's research is still in the experiment, and a small number of commercial products that have been launched are still basically in the door test phase. Before this, a medical service provider in the United States became one of its coordination customers. In 2014, Li-lsi came out and can realize two-way data transmission, but only open to cooperative customers.
In Li-Fi, in addition to PureLi, similar technologies were implemented in the ACEMND project operated by another European team. Shanghai Fudan University has also been developing related technologies. Researchers say that the study of Li‐Fi has multiple advantages;
The first is fast transmission. One-way transmission of the fastest 150Mbps, two-way 110Mbps, but in the end there is a great potential to upgrade, up to lGbps, IOGbps above the level.
Followed by security. According to reports, the characteristics of light determine that it cannot transmit signals through the wall. At the same time, the uplink and downlink channels of Li‐Fi operate independently. Hackers must be in the same room and invade the two channels to complete a real sense. attack.
Third, no electromagnetic interference. Although current aviation regulations allow passengers to use electronic products on planes and important medical equipment in hospitals, copper nets are embedded in the walls to avoid mobile phone interference, but they may still be subject to interference, and optical wireless communication is used in these sensitive locations. You can avoid interference.
Of course, Li-Fi also has some problems, such as how to distinguish which is the light data that should be received under complex lighting conditions in the room. Once blocked, it cannot be sent or received. These problems need to be further addressed.
In spite of this, relevant organizations are still very optimistic about their investment value and growth potential. The Edinburgh Department of Research and Innovation believes. With the popularity of LED express delivery, as long as the development of mature Li-Fi technology, will replace Wi‐Fi one day. According to the conservative data of relevant agencies, after 5 years, visible light communication technology market space will be more than 15 billion US dollars.
It is reported that consumer products of PuteLiFi have already started R&D, but no release schedule has been announced. At present, before the technology was formed, many of the visions of commercialization were cut into the construction of public facilities.
Some scientists say that they are very optimistic about this new technology, which will promote the shift of mobile Internet to the development of cell-based networks. And LiFi can become a bigger market if it becomes a substitute and upgrade for the Internet of Things.
