Alaska X 88X2010 and 88X2011 10 Gigabit PHY devices are designed to accelerate the mass deployment of 10 Gigabit technology into the LAN and WAN markets.
Transceiver speeds SAN development
Marvell reckons it is leading the transition to next-generation storage area network solutions with the industry's most advanced 10 Gigabit Fibre Channel transceiver.
The Marvell Libertas 802.11g solutions will accelerate the growth of WLAN into the consumer and enterprise markets by offering advanced features to enable robust video streaming and the highest level of security.
The Marvell Libertas 802.11g architecture has been carefully designed to be fully backward compatible to the legacy 802.11b infrastructure in order to support the millions of current 802.11b users.
As such, the current 802.11b installed base will not incur additional costs or downtime when transitioning to an 802.11g environment.

"Marvell has anticipated the issue of forward compatibility to the final IEEE 802.11g standard as it becomes ratified", stated Bob Wheeler, Senior Analyst for The Linley Group.
"The Marvell Libertas 802.11g family of WLAN solutions is well-positioned to take advantage of the large number of 802.11b users, not leaving them stranded and enabling a full featured migration strategy".
"The Marvell Libertas 802.11g solutions seek to extend wireless LAN beyond traditional networking applications such as client adapter cards and access points", stated Dr James C Chen, Marvell's Wireless Product Marketing Manager.
"The Libertas 802.11g solutions allow users to enjoy the freedom of 54Mbit/s wireless connectivity by offering advanced video streaming and security technology that will be forthcoming in IEEE standards such as 802.11e quality of service (QoS) and 802.11i advanced security, respectively".
In order to provide a 54Mbit/s wireless connectivity that is both fast and secure, Marvell has incorporated QoS technology that allows higher network "priority" to guarantee smooth data transfer in high bandwidth applications such as high resolution video streaming.
Also, dedicated AES/CCM hardware security acceleration engine is employed in addition to a flexible processor-based architecture for enhanced security and privacy.
To further increase 54Mbit/s speed and range, Marvell continues in its tradition of providing sophisticated RF and DSP technology to reduce the effect of wireless "echoes" that exist in many environments.
These echo reduction techniques include Marvell patent-pending Channel State Estimation technology that allows farther and more robust wireless connections.
