Bytelight has developed a positioning service based on LED lighting, which allows the program to calculate the current position in one second, with an accuracy of up to one meter. The LED positioning system is implemented by LED luminaires on the ceiling. The luminaire emits a flashing signal like the Moss telegram password, which is then received and detected by the user's smartphone camera, and the user does not need to point the camera to a specific direction. It is also possible to receive a direct source signal that is fed back.
Bytelight co-founder and CTO Daniel Ryan pointed out that Bytelight is currently the only company that masters the core technology of LED indoor positioning, but there are still some problems to be solved. For example, Wifi has not been widely popularized yet. However, this positioning system needs wifi support and setting. “Geographic Fence†– A specific building to authenticate users to determine the precise location of a customer in a mall or grocery store.
Bytelight plans to promote this service to more service venues. For example, in the bookstore, only the quick search function is needed. The LED positioning system can help users find the books they want to read, thus reducing the burden on the bookstore staff. 
Recently, Bytelight CEO announced that it will build a strong indoor LED positioning service. ByteLight raised $1.25 million from Van Gogh Venture Capital Fund VantagePoint Venture Partners and other investors.
