Disney Researchers invented ways to network VLC devices using IoT technology

Sep 18, 2015 10:03 IST

Disney Researchers on 7 September 2015 announced that Internet of Things (IoT) technology can be successfully used in Visible Light Communication (VLC) devices to network them and thereby creating smarter devices.

To prove this, they successfully experimented with Light Emitting Diode (LED) based bulbs.

It was announced in a research paper titled Linux Light Bulbs: Enabling Internet Protocol Connectivity for Light Bulb Networks.

How LEDs were made smart by using IoT?

Off-the-shelf commercial LED light bulbs were modified so that they could send and receive visible light signals. For this, a System-on-a-Chip running the Linux operating system, a VLC controller module with the protocol software and an additional power supply for the added electronics were introduced to them.

The Linux OS was created in such a way that the signals transmitted through LEDs compatible with Internet protocols.

Now, these VLC-enabled LEDs were used to broadcast beacons making it possible to detect the location and communicate with the objects like toys and communication devices like smart phones, etc.

What is Internet of Things (IoT)?

IoT refers to a network of internet connected devices which are embedded with electronic sensors, light operating systems and data transmitting technologies.

By using the Internet the data collected by sensors in the IoT devices like cars, power systems and even as small as tooth brushes transmitted to other networked devices and data processing systems.

Thus, the information generated by processing the data will be used by the companies and individuals to make better decisions and create smarter environments.

As per an estimate, there will be roughly 100 billion IoT based devices in the world by 2025, with 2 million new sensors deployed every hour.
