A university in Boston to announce the start of a program sponsored by the National Science Foundation to develop wireless communication technology based light, not radio waves (RF), which are usually used by Wi-Fi signal. WiFi wireless connection types have become the most sought-after alternative to connect all electronic devices or gadgets, but there are still obstacles, especially the placement of the router, which can be accessed more widely. Scientists hope this technology may be used for data communication in the light emitting diodes (LED) power saving to create "Smart Lighting" faster and safer than the existing network technology at this time.
Technology called Data Transmitting LED work as a light where you need a network connection, the light switch on living. Service is a signal, each lamp can be a mediator with one another so that during the light-light, so the reach of the signal will continue to be obtained. Unfortunately for the speed problem, "the network lights" this can only transfer data between 1 - 10 Mbps, but of course a useful discovery in the future.
Imagine if a computer, iPhone, TV, radio and thermostat can communicate with you when you enter the room only by pressing the button on the wall of light without using a cable, "said BU Engineering Professor Thomas Little. "This can be done with LED-based communications network while also providing a light - all this with the use of low power, reliable, free of interference and electromagnetic waves.
In the end, the system is expected to replace the existing lighting system at this time, such as changing the bulb with LED lights. "
Boston University scientists will concentrate on the development of computer network applications, especially solid state optical technology that will soon become the backbone of this network.
This is a unique opportunity to create an important technology that is not only possible power efficiency in lighting, but also create a secure wireless technology, "Little added. "While we divert the traditional system of LED lighting in several years, we can simultaneously build a communications infrastructure that is more rapid and secure with affordable cost along with the application of new and previously not possible."
With the increasingly popular with LED lighting systems, light-based communication network of the most extraordinary will be created. A wireless device that is within the reach of LED can send and receive data via light, initially with a speed of 1 to 10 megabit per second - supported by each LED that functions as a network access points. The network will offer the potential use of the bad with a far More than most of RF technology that is at this time.
Furthermore, because the light does not penetrate surfaces such as walls, this technology also provides the security level higher because data communication can not be disadap from the outside. In the negative side, the nature of light, this will complicate access the network from a different room, this also means that the network connection is established only when the lights are switched. Furthermore light LED requires much less power than RF technology that will be more cost-effective in the long term. Cpt I realized this technology ...
