Supports Multi-Gigabit Speed, Reliability and Quality for
Next-Generation, Very High Throughput WLAN Products
series
OVERVIEW
The Marvell® Avastar 88W8964 is a new member of its award winning Avastar WiFi processor family. It
features 160MHz bandwidth and Multi-User Multi-Input Multi-Output (MIMO) while achieving 2.6 Gbps
peak data rate for high speed, secure, and reliable access points and smart gateways.
For security, the Marvell Avastar 88W8964 supports high-performance 802.11i security standards
through implementation of the Advanced Encryption Standard (AES)/Counter Mode CBC-MAC
Protocol (CCMP), Wired Equivalent Privacy (WEP) with Temporal Key Integrity Protocol (TKIP),
Advanced Encryption Standard (AES)/Cipher-Based Message Authentication Code (CMAC) and WLAN
Authentication and Privacy Infrastructure (WAPI) security mechanisms.
The 88W8964 delivers 802.11e Quality of Service (QoS) to reduce latency for video, voice and
multimedia applications. In addition it provides 802.11h Dynamic Frequency Selection (DFS) for
detecting radar pulses when operating in the 5GHz band. The Marvell Avastar 88W8964 has a PCI
Express v2.0 host interface that is backwards compatible with v1.1.
APPLICATIONS
88W8964 is targeted at enterprise access points and hotspots, retail access points, service provider
gateways and set-topboxes. With a peak PHY rate of 2.6 Gbps, the 88W8964 enables retail access
points with the highest data rates. The high data rates, 4x4 configuration in combination with the
industry’s most mature and proven explicit and implicit Beamforming implementation enables service
provider gateways and set-top boxes capable of multi-stream 4K video content distribution over
wireless in residential environments.
BEAMFORMING TECHNOLOGY
Beamforming is a specialized method of radio-frequency transmission used in WiFi access points.
Beamforming enhances the signal reception at the client, significantly extending the WiFi signal
coverage. A feature of all Marvell Avastar SoCs, Marvell’s Beamforming technology doesn’t require a
special antenna nor will it incur any other cost increase of the wireless subsystem. The result is an
increased throughput over a range compared to existing technology, depending on the environment. In
addition to improving rate over range, the Marvell Transmit (Tx) Beamforming technology increases the
battery life of any device connecting to the Avastar 88W8964.
MULTI-USER MIMO TECHNOLOGY
Multi-User MIMO allows simultaneous sessions from one access point to several client devices at the
same time. The 88W8964 supports three 1x1 or a mix of 2x2 and 1x1 connections at the same time.
