Richard read an article about students in San Jose, who are hanging out under light poles because of something called LiFi? You can get over 225GB doing so, but it's limited to where the light can transmit. Leo says that LiFi has potential since light poles can double as access point stations for public Wi-Fi. But with LiFi, it uses light to transmit internet bandwidth. Chattanooga also offers something similar by using GB broadband through the electrical power lines. It's getting pushback from internet service providers, though, who say it impacts their business. But Leo says that 5G is going to change everything.
