Researchers at Boston University’s College of Engineering have an revolutionary idea, which they’re now designing a new communication system that is made up of light bulbs for transmitting your data.
The light bulbs are those low-powered LEDs, which could utilize an optical communication system that transmits your data wirelessly. It works by having the LEDs switching rapidly on and off, as if sending various optical communication pulses and patterns that carry your data. Each light bulb will be a network entry point by itself which can transmit data at speeds of 1 to 10 Mbps.
This kind of optical communication system definitely comes in handy. As there isn’t a need to install additional network equipments and wiring in order for your computers to communicate with each other in an office or a house. Since we all need light bulbs to keep our rooms brightly lit, it’s definitely a much handier system to have.
I assume the light bulbs will be switching very rapidly which human eyes are hard to detect the changing of the lights. So, it shall work exactly the same as a normal light bulb as well as keeping our computers connected.
The light-bulb network is said to be more secure than the current RF techniques as it requires linked devices be in line-of-sight and it draws comparatively low energy than conventional WiFi radios. Imagine, when you walk in a room and flip the switch of wall light, and your iPhone, TV, radio, and other gadgets could all communicate to each other and you.
