Signify has created a new light bulb that has light-emitted wifi, called Trulifi, which can transmit data at speeds up to 150 megabits using light waves.
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.
