OSU Researchers Increase WiFi Bandwidth To 50-100 Megabits Per Second
In their latest research work, a team from Oregon State University (OSU) has achieved major breakthrough in increasing the bandwidth of WiFi systems. Having blazing fast internet speed is a dream for thousands of netizens across the world. With WiFi spots now not being limited to office spaces or homes, Internet users in public places like parks, malls or restaurants demand high-speed WiFi connectivity. It seems that if this research ever goes mainstream, netizens will have many reasons to cheer. Using inexpensive components, the OSU Researchers employed LED lights for transmitting information and found that the bandwidth is increased by 10 times. The biggest win for this research is that it can be integrated with existing WiFi systems and therefore doesn't involve extra costs overhead.
In a “free space†optical communication system, it has become possible to have wireless data transmission with LED light modulation. In their first prototype device called 'WiFO', an invisible cone of light is created using LEDs in about one meter square in which the data can be received. Furthermore, a hybrid system was also developed to tackle the problem of small area of usability. This system switches between many different LED transmitters installed on a ceiling in the area where WiFi coverage is needed. Small sized photodiodes are used as receivers, which keeps the costs very low. These receivers can be connected through USB ports or simply be incorporated in the next-gen mobile devices like smartphones, tablets and laptops.
The team confident that the WiFo system can be built into a commercial product and has already started looking for companies interested in developing & licensing the research work. The system has been tested to deliver data at up to 100 megabits per second. Even if some existing WiFi systems promise a similar bandwidth, in actual usage it is divided among the number of devices and therefore each user ends up receiving a speed of just 5 to 10 megabits per second whereas the hybrid system is said to deliver 50-100 megabits to each user. Isn't that something?
We await the day when the common video streaming problems, the unending stalls in buffering and pages taking infinite time to load come to an end. What are your thoughts about the significant increase in WiFi Bandwidth? Share with us in comments below.

Satheesh S.Sinternet is part of human day to day life .i think in future generation wi-fi band width should need more than this...... so it good technology for improving this.
