Description

Technical field [0001] The present invention relates to the technical field of visible light communication, in particular to a portable mobile phone externally connected to visible light communication equipment. Background technique [0002] Visible light communication is a very promising communication technology. There were experiments in visible light communication more than a hundred years ago. Limited by the technology at the time, it was not developed. Today's visible light communication technology is developing rapidly, with electromagnetic wave communication. Incomparable advantages, the transmission speed of visible light communication such as LED lights is fast, unlike WIFI and 4G networks, which are limited to the network speed due to the increase in the number of users, but it still has defects that are difficult to compensate, such as opacity When the object is blocked, communication will be restricted. The technology proposed today is to add external devices to mobil...
