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.
Ruckus Wireless and Aruba Networks have announced a collaboration on the development of 802.11n wireless LAN products and technologies.
Under the joint development agreement they say they are creating "new high-speed 802.11n solutions that combine centralised control of wireless networks with essential capabilities not found in emerging pre-N products, such as smart antenna technology and dynamic RF optimisation."
The new products will integrate features such as dynamic signal path steering, interference avoidance and real-time optimisation controls developed by Ruckus Wireless, with adaptive radio management (ARM) and wireless intrusion prevention (WIP) technologies developed by Aruba Networks.
The resulting products will "automatically select the best channel and power levels for 802.11n access points, detect 802.11n rogue access points and continuously mitigate interference by selecting the best signal path in real time based on the RF environment, receiving device and traffic type."
802.11n, the next step in Wi-Fi, is designed to significantly boost the capacity of wireless networks by more than quadrupling the speed of the current-day technology to 200 Mbps or more by using multiple transmitters and receivers simultaneously.
According to Ruckus and Aruba, "this also increases the number of things that can go wrong with the integrity and security of the transmission. 802.11n will also permit doubling of the channel width to increase physical data rates. This, and the added transmit and receive radios, raises the potential for interference with nearby wireless devices. Therefore, the ability to dynamically control where Wi-Fi signals go, adjust the multitude of new parameters and tightly secure the RF environment is key to a robust 802.11n network. Ruckus Wireless and Aruba Networks will work to develop an application-focused control framework to address these difficult real-time optimisation problems."
They claim that these new products will be delivered immediately upon ratification of the 802.11n standard and say they are expected to be "the first, centrally managed enterprise 802.11n solution that adds important wireless stability features necessary to ensure predictable performance".
The two companies will also enable Ruckus Wireless access points to be managed by Aruba's mobility controllers to support enterprise telecommuters and emerging managed WLAN services by service providers.
Aruba and Ruckus Wireless will also collaborate to "solve the deployment and security challenges created by the new 802.11n wireless standard by optimising the selection of 20MHz or 40MHz operational modes, burst modes and other capabilities that are introduced in the new standard."
Ruckus Wireless plans to extend its patent-pending BeamFlex technology to 802.11n, making it available by the end of 2006. BeamFlex-N is expected to be capable of supporting three or more simultaneous high definition (HDTV) video streams.
