Australia begins test of Wi-Fi via TV antenna

Australia's Commonwealth Scientific and Industrial Research Organization has started testing its wireless broadband technology, which uses existing TV antennas, at the first National Broadband Network roll-out site of Smithton in Tasmania.

The system, named Ngara, works by installing antennas on existing TV broadcasting towers that transmit wireless broadband to households through their existing TV antennas, although slightly modified as some components in existing antennas don't allow them to be used as transmitters.

While the uplink test was a success, getting data downloaded was still a work in progress. "The team is only able to beam form to … Read more

Wi-Fi, meet the TV antenna

Australia's Commonwealth Scientific and Industrial Research Organization tomorrow plans to unveil a breakthrough in wireless technology that will allow multiple users to upload content at the same time while maintaining a data transfer rate of 12 megabits per second (Mbps), all over their old analog TV aerial.

The technology, named Ngara, allows up to six users to occupy the equivalent spectrum space of one television channel (7 megahertz) and has a spectral efficiency of 20 bits per second per hertz. Ngara can handle up to three times that of similar technology and maintains a data rate more than 10 … Read more
