Marvell, the maker of wireless chips, plans to release the 8864 chip for the wireless 802.11ac Wi-Fi standard, which is capable of up reaching gigabit speeds. The release is scheduled for some time next year. Excerpt from Computerworld:
The Marvell 8864 chipset increases performance by using four antennas to receive and four to send data, a configuration which is referred to as simply 4×4. Sending and receiving data using multiple antennas is possible thanks to a technology called MIMO (Multiple-Input Multiple-Output), which is already used in both Wi-Fi and LTE networks.
In addition to MIMO, Marvell’s chipset also uses a technology called beamforming, which improves performance by aiming the signal at the receiver. The way Marvell has implemented beamforming means smartphones, tablets and laptops don’t have to proactively support it to get the advantages.
The combination of multiple antennas with beamforming results in higher speeds, as well improved range and reliability. For users the improvements also mean longer battery life, because devices such as smartphones can “get on and off the air” faster, Giordano said.
To take full advantage of the 8864 chipset’s capabilities, clients also have to have a 4×4 antenna configuration, but other clients will also see significant improvements, Giordano said.
The Marvell chipset will be used on a multitude of different products, including access points, routers, gateways, video bridges and set top boxes, the first of which will start shipping in the middle of next year.
