Marvell has introduced the TopDog 11n-450, an 802.11n 3x3 WLAN solution with three spatial streams, and touted to be the first 802.11n chip operating at 450Mbit/s.

With maximum bandwidth more than eight times faster than 802.11g 54Mbit/s versions and 1.5 times faster than current 802.11n 300Mbit/s offerings, the new product will enable significant performance enhancements for notebooks and desktop PCs, printers, routers, STBs, DTVs, gaming devices and DVD players and recorders. The solution also provides 500 per cent increased range over 802.11g, as well as 160 per cent increased range compared to competing 802.11n solutions.

"Compliant with the 802.11n specification, the new Marvell TopDog 11n-450 chip also offers Marvell-engineered enhancements to the specification, such as special time block coding, that helps maintain higher throughput over longer distances," said Sameer Bidichandani, senior director of technology strategy, Marvell Semiconductor.

With the TopDog 11n-450, a user can move further from their wireless source while performing real-time streaming video in multiple sessions, without experiencing weaker signal strength, freezing frames or slower throughput.

The solution delivers 3x3 capabilities with three transmitters and three receivers, and is built on 90nm CMOS process technology making it a lower-power, lower-cost solution on top of its higher range and performance. The product is backward-compatible with previous 802.11a, b, g and n versions and currently sampling. TopDog 11n-450 is expected to begin shipping in volume next quarter.
