Providing audio via light is a one-way transmission - and also not even close to being new technology. For example, every movie theater or auditorium has the exact same technology in place for the hearing impaired. Special headphones receive the infrared signal and decode it into audio.
Providing Internet connectivity would require a two-way connection. A person's device would have to have a receptor and emitter. This could potentially be the camera and LED flash. Maybe you could go so far as to use the front camera and emit infrared via the screen. But, that means the device has to be in direct line-of-sight of the source. Once the phone or tablet goes into your pocket the connection is lost.

The article sounds like complete bunk.
