Wherever you are, every LED source can be turned into a hotspot. Li-fi can be defined as a green technology for device-to-device communication in the Internet of Things (IoT) but it requires a high precision of the light beams so that it arrives to the "receiver" without interferences. The high-reflectance segmented reflectors in vegaled aluminium are the right answer to this need, avoiding to the interferences typical of lenses.
