Marvell Debuts 802.11n 4x4 Wi-Fi with BeamForming

Marvell introduced its Avastar 802.11n, 4x4 single-die solution for enterprise access points, service provider gateways, high performance home routers, media and mobile servers, Digital TVs (DTVs), and Set-Top-Boxes (STBs).

The Avastar 88W8764 leverages 4x4 technology (four independent transmit-receive RF chains) to support three Multiple Input, Multiple Output (MIMO) spatial streams, thereby delivering the highest throughput, best wireless coverage and most robust link quality for media streaming and other high bandwidth data applications.
Marvell rates this performance at up to 450 Mbps. Data can be steered towards the client using its Tx beamforming capacity. The four RF chains guarantees the most stable and robust high order 802.11n Modulation and Coding Scheme (MCS) data rates. Additionally, it supports the national Chinese standard for Wireless LANs (WAPI), Wi-Fi Direct, Tunnel Direct Link Setup (TDLS), and Space Time Block Coding (STBC).

"Wi-Fi has become the critical common link in today's mobile communications as users now expect and demand seamless, high-performance, robust and secure connectivity, zero latency and crystal clear communication between all their connected devices no matter where they go," said Weili Dai, Co-Founder of Marvell. "Marvell has a proven track record as the world leader in Wi-Fi for enterprise, consumer and mobile applications delivering robust, high performance and high bandwidth, highly secure and seamless wireless connectivity. I believe Marvell's groundbreaking 802.11n 4x4 Wi-Fi solution will fundamentally change the wireless landscape and truly enable the entire spectrum of always-on consumer products."
