You don&#x27;t need separated routers each LED light bulb can be used as an access point, there are already LED bulbs with WiFi because people will buy anything that looks like an Apple product.<p>You need WiFi still because the LiFi channel is only one way.<p>It can still sorta work through some pockets but rule of thumb is that if your mobile device is in your pocket you don&#x27;t need the fastest speed possible and you can fallback to WiFi.<p>But yeah the tech is kinda silly in general.
