What happens if a light bulb technology become Wi-Fi? Imagine if you turn on the TV, radio, computer, iPhone and other electronic equipment, only by pressing the button lights in the walls and without cable?

This can occur, after the program conducted by Boston University, majoring in Engineering and sponsored by the National Science Foundation. These programs generate wireless communication technology that follow light speed, not the radio frequency (RF), which are usually used by Wi-Fi signal. This technology is expected be used to create new channels of communication through the LED (Light Emitting Diodes) are energy efficient and faster than existing technology, the network now.

Technology developed the ability to make the LED will be almost the same functions with the access point and Wi-Fi. According to Thomas Little, one of his professors, majoring in engineering at Boston University, changing a light bulb, such as access point and Wi-Fi can be done with LED-based network that provides light, with the use of low power and free from interference waves electromagnetic.

After the network based LED used properly, it can also change the lighting system functions, like changing the LED light. Meanwhile, the main of the network LED is a form of optic technology, solid state applications for the development of network computers.

With the expansion of the LED lighting system, the communication network based on light, can be created. Take the example of a wireless device within range of LED can send and receive data through the access point and each LED, with a speed of 1 to 10 megabit per second bandwidth and larger than the Wi-Fi network.

The advantage of the LED system for communication network that is maximum protection, because light can not penetrate walls, so that security is much higher. In addition, the LED system only requires little power compared to Wi-Fi so more sparingly. The disadvantage, because can not penetrate the wall, then access to different networks, will be difficult, and the network will only be obtained when the lights are switched on, so the electricity to be rather extravagant cost.
