This invention protects the use of at least two radiation sources to achieve an increased transmission rate. It also covers the use of infrared or ultraviolet radiation sources. This makes it possible to use a phase relation between the radiation source for emitting non-visible light and one further radiation source for transmitting a portion of the data. This can result in improved reliability.
It seems inevitable that at some point it will eventually VLC will gain traction in the market. This patent could prove useful as robust and reliable VLC connectivity in busy environments is needed in high value or busy environments.. Once developed, more robust low cost connectivity using single or fewer LEDS could become viable.
Technical: It is not clear (due to my limited German) with the short wavelengths, wether or not phase relationships alone is enough. However, the simultaneous use of different modulation schemas is likely a more valuable feature.
Risks of higher end-to-end costs: due to need to orchestrate and coordinate the multiple LED sources to avoid the use of duplication modulation schemas. This added complexisty could create a need for common standards increasing NRE and R&D budgets, which all together would likely delay wide-scale VLC adoption.
Security: it should not be assumed that the VLC solutions are always more secure than WiFi, especially in outdoors scenarios or where there are windows. As VLC becomes popular folks will likely invest to find ways to defeat the technology.
Competitors and Barriers: there are several key stakeholders and large industries that could actively or passively choose to delay VLC especially where it competes with existing and established technologies. These companies will likely have committed significant amounts funds onto their near-term roadmaps.. Applications: 1) Car-to-Car and transport; 2) Intelligent Street lighting and smart cities; 3) Emerging markets and rural areas. Companies: Communication, IoT and personal devices companies....beyond 2020.
Thank you for your sharing your business insights, CBX001.
Any application that requires transmission of large amounts of data can profit from this invention: video, bitcoin mining etc.
This patent could be very interesting for military or security applications. Since UV cannot penetrate walls and windows of a room, data transmission on basis of LED/UV cannot be sniffed out from the outside - compare that to WiFi!
The nascent LiFi technology transmits data by switching one LED light bulb off and on. Think morse code going so fast, you cannot see the flickering. This patent takes the idea several steps further. It will be very easy to check if anyone is using this patent. But only time will tell if LiFi will use phase relationships to improve reliability or increase transmission speed. I like the patent's twist to include infrared or UV light. Check out this article to see how LiFi could implement infrared light: https://www.sciencealert.com/a-new-type-of-li-fi-has-reportedly-cracked-40-gigabits-per-second-100-times-faster-than-regular-wi-fi
