When I first read about LiFi (wifi where light is used instead of radio waves), I started imagining a whole new and bright future equipped with potentially hundreds of GHz of available frequency and Terabits flowing to and from my devices. The world would definitely be a much better place, with internet a thousand times fasterRead more

Radio spectrum, the backbone of 3G, 4G, 5G, Wi-fi, bluetooth, radio and television networks and broadcasting, is getting crowded, especially in densely-populated cities like Hong Kong and Singapore.
Martyn Wingrove discusses the next-generation light technology that offers better availability, capacity, reliability and security than wifi Wifi’s radio communications signal does not transmit well through steel decks and bulkheads. And while engineers have come up with creative workarounds, overall, improvements have been limited and costs are considerably higher than expected.
