Marvell shows off four-channel 802.11n chip

Written by Nick Farell


New generation of wireless gear
Chipmaker Marvell claims to have developed a four-channel 802.11n chip which it is putting into the shops. The chip, with the catchy title Avastar 88W8764 is being touted as the "new generation" of wireless gear. Based on a single die, the chip is targeted at enterprise access points and service provider gateways to routers, servers, digital TVs, and set-top boxes.

According to Marvell, the beastie uses open standards for controlling and managing network access and can lead the way for four independent transmit-receive radio frequency (RF) chains while at the same time. This means supporting three multiple input, multiple output (MIMO)
special streams for as much as 450-Mbps data rates. Marvel said the four RF chains create stable and robust high-order 802.11n modulation and coding scheme data rates.

Weili Dai, co-founder of Marvell said that Wi-Fi punters expect and demand seamless, high-performance, robust, and secure connectivity, zero latency, and crystal clear communication between  their connected devices. Marvell tells us that the Avastar family supports a wide spectrum of
consumer products including tablet computers, smartphones, eReaders, digital cameras, laptops, printers, access point routers, Blu-ray players, and high-definition (HD) television sets. No word on prices yet.

This will be nice if they start putting it in TV and Set top Boxes, n 2.0 at 300mpbs is fast and streamless as it is, but if this chip is small and cheap to put in devices that would be great. Would love wireless N on my printers and cameras, etc... especially on smartphones!

Pretty much all current high end smart phones already have 802.11n

But does it do 5Ghz Wireless-N? There are enough networks operating on the congested 2.4Ghz band that getting a router that supports Dual Simultaneous Wireless-N (on 2.4Ghz and 5Ghz) is important if you want decent throughput, especially if you plan to use 40Mhz double-width channels (necessary for 150mbps per stream). The 5Ghz band has many more channels (20 vs 11), they are spaced more widely to limit interference, and there are fewer networks operating which limits congestion.

sure they do and when I connect it to my 300mbps wireless n router I don't get 300mbps speed. Yea great n speed on phone... whatever they say its not n 2.0 speed on the smartphones. This would make it so. Yes all n gear supports 5 ghz, but how well it does who knows.
