Telstra has revealed the addition of almost one million new mobile services in the six months to December 2011, but Sensis revenues plummeted 24 percent in 12 months.
The test hardware operates in both the 4.9GHz licensed public safety and 5.8GHz unlicensed bands. However, the company says that other bands including the 2.4GHz (unlicensed ISM band), the 3.65GHz (broadband wireless services band) and the 5.9GHz (telematics/ITS band) may also be supported.
Cohda claims that its receivers achieve an increase of 7dB to 12dB in sensitivity over standard WiFi, an ability to maintain links in NLOS environments at speed of up to 320kph, increased coverage into notorious black-spots such as urban canyons and improved system capacity thanks to robust links at higher supported data rates. "These advancements will result in greater coverage and capacity with a significant reduction in node density as compared to current municipal wireless networks, resulting in a dramatic improvement of return on investment," it says.
Cohda Wireless was founded in 2003 by a group of research scientists working at the University of South Australia's Institute for Telecommunications Research, and incubated by ITEK, the University's incubator. In December 2003 Cohda secured pre-seed funding from SciVentures Investments and has attracted additional early stage private investment as well as two significant grants from the Australian Government. In August 2005, Cohda officially launched its brand and established a presence in the USA, its primary target market.
In August 206, Cohda launched a website (www.thedirtylittlesecret.net) "to help expose the limitations of 802.11 in mobile and city-wide, outdoor wireless deployments. It claimed that "many vendors have tried to use 'plain vanilla' 802.11 in city-wide deployments, achieving mixed results."
