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.
Navini Networks, key supplier of WiMAX gear to both Unwired and Austar, has unveiled a technology that it claims will enhance the performance of mobile WiMAX networks such as those planned by Unwired and Austar.
Navini's Smart WiMAX product combines the smart beamforming technology currently in commercial service on Navini networks around the world, including Unwired's, with beam-formed MIMO, which, Navini claims, can double the data throughput for mobile WiMAX subscribers.
"While some vendors have taken an 'either MIMO or beamforming' approach to advanced antenna systems for mobile WiMAX, Navini's unique approach combines them to improve the performance of mobile and stationary users," said Sai Subramanian, Navini's VP of product management and strategic marketing.
"We've seen beamformed MIMO signals demonstrating over 12dB gain (16 times increase in received power) compared to standard MIMO. In many locations where standard MIMO signals are not receivable, the enhanced beamformed MIMO signal is not only received but decoded using 16 QAM (fast) or 64 QAM modulation (very, very fast). Additionally, beamforming delivers over 9dB gain (8 times increase in received power) on the uplink, which is critical to getting broadband performance from low powered devices," Subramanian claimed.
Navini says it is taking orders for its Smart WiMAX systems for 802.16e Mobile WiMAX deployments, which include support for Wave 1 and key Wave 2 features (including beamforming and MIMO). The company recently staged the first demonstration of its currently-shipping wireless base stations operating in 802.16e-2005, mobile WiMAX mode.
