Article is titled " Explore Global visible light communication ( LI-Fi) market comparison by types, application, and by region. Initial site: " WhaTech" Date: Nov 2 2017. There are a couple of websites shown where further access to complete reports are shown.....don't know if these are pay to access or not, but Plaintree is listed as a Key company along with several others including General electric, Panasonic, Lightpoints etc. The latter are definitely some of the BIG GUYS, so to have Plaintree's name mentioned in their company is pretty god.
