'Microrings' - Ultimate Wireless Communication

1. Researchers based in Purdue University have developed a miniature device capable of converting ultrafast laser pulses into bursts of radio-frequency signals, a step toward making wires obsolete for communications in the homes and offices of the future.Such an advance could enable all communications, from high-definition television broadcasts to secure computer connections, to be transmitted from a single base station, said Minghao Qi, an assistant professor of electrical and computer engineering.The team fabricated tiny silicon "microring resonators," devices that filter out certain frequencies and allow others to pass. A series of the microrings were combined in a programmable "spectral shaper" 100 microns wide, or about the width of a human hair. Each of the microrings is about 10 microns in diameter.

2. Thus a single base station would be sort of a computer by itself, perhaps a card inserted into one of the expansion slots in a central computer. The central computer would take charge of all the information processing, a single point of contact that interacts with the external world in receiving and sending information."There is no end to improvement......as i say.....just when we thought WiFi is the end of home trouble shootings for easy connectivity...this goes many steps ahead.....
