Backwards compatible and may boost existing wireless n performance too.
If there’s one thing that’s almost as frustrating as the interminable ratification process of 802.11n it is the short sighted speed limits. So praise be to Marvell for doing something about it…
The networking specialist has announced a new enhanced – yet completely compatible – version of wireless n which offers a theoretical maximum performance of 450Mbps, 50 per cent more than standard 802.11n’s 300Mbps.
It is not just data rates which get a kick however since Marvell claims its 802.11n revision also provides 60 per cent more range compared to the existing draft solutions on the market.
“Marvell is first-to-market with an 802.11n 450 Mbps solution so manufacturers can deliver industry-leading wireless range and performance to consumers who are seeking faster and more powerful Wi-Fi capabilities,” said Sameer Bidichandani, Marvell senior director of technology strategy. “Compliant with the 802.11n specification, the new Marvell TopDog 11n-450 chip also offers Marvell-engineered enhancements to the specification, such as Special Time Block Coding (STBC), that helps maintain higher throughput over longer distances.”
TopDog 11n-450 delivers 3×3 capabilities with three transmitters and three receivers and is built on 90nm CMOS process technology meaning it should use less power and cost less to produce than existing solutions as well. Lastly the chip is backwards compatible with 802.11a/b/g.
Too much good news all at once? Well, with volume shipping expected to begin next quarter and a full showcase planned for CES we may finally have a breakthrough in 802.11n to smile about…
