Millimeter-wave photonics is a truly disruptive technology for high frequency applications. It offers unique capabilities such as ultra-wide tunability and low-phase noise which are not possible with competing technologies, such as electronics. What this will mean in practical terms is not only ultra-fast wireless data transfer over telecommunications networks, but also a whole range of new applications.
One of these, a 60GHz Photonic Wireless System, was demonstrated at the ICT 2008 exhibition in Lyon and was voted into the Top Ten Best exhibits. The system allows wireless connectivity in full high definition (HD) between devices in the home, such as a set-top box, TV, PC, and mobile devices. It is the first home area network to demonstrate the speeds necessary for full wireless HD of up to 3Gb/s.
The system can also be used to provide multi-camera coverage of live events in HD. The same technology has been demonstrated for access telecom networks and has delivered world record data rates of up to 12.5Gb/s over short- to medium-range wireless spans, or 1500 times the speed of upcoming 4G mobile networks.
One way in which the technology can be deployed in the relatively short term is wirelessly supporting very fast broadband to remote areas.
To be continued.
