| Ralink Unveils 802.11n 1T2R Half-Sized Minicard Solution Ralink Technology announces the launch of Ralink's RT2700 802.11n 1T2R (one transmit, two receive) chipset available in a half-sized PCIe minicard. The RT2700 chipset is suited for notebook and desktop PC's and offers the high throughput and coverage of 802.11n at a price point approaching current 802.11b/g solutions. RT2700 based solutions can be certified for Wi-Fi Alliance's 802.11n draft 2.0 standard, and supports the latest Wi-Fi features such as 802.11i security, including Wi-Fi Protected Setup and 802.11e quality of service which can prioritize voice and video over data transfers. The RT2700 uses a 1T2R architecture, capable of up to 300 Mbps downstream and 150 Mbps upstream PHY rates. Most of the power for 802.11n designs is in the transmit circuitry. The RT2700 1T2R architecture offers a significant power savings and a bill of materials cost advantage since it has one less transmitter. RT2700 is fully backward compatible with the existing industry wireless standards such as 802.11a, 802.11b and 802.11g. The chipset is currently available with an 802.11n evaluation board, reference design and driver software for the Windows Vista operating system. write your comments about the article :: © 2007 Computing News :: home page |
