Today, the company is ready to break a big barrier. Quantenna's QHS 802.11n chipsets have a 4x4 MIMO antenna system with Transmit Beamforming, with the stated goal of being used in the streaming of high-definition multimedia content or in HD IPTV setups. The company says its chips use the 5 GHz and 2.4 GHz bands simultaneously, along with adaptive vector mesh routing to reduce communication latency. The three chips announced today are the QHS450 (450 Mbps max link speed, 200 Mbps max throughput), QHS600 (600 Mbps/400 Mbps), and QHS1000 (1 Gbps/600 Mbps)."</em></p><p>I'm all for more speed, but never at the expense of reliability - and right now I don't think 802.11n is reliable, largely because compatibility is theoretical without a finalized standard. 600 mbps sounds great - even if if means real-world speeds of half that - but until that spec is finalized, whether or not you'd actually see if working is anyone's guess.</p>

At this point in time, I don't see how 600mbps could even be useful. I've never used anything faster than 10mbps internet, and 54mbps is just fine for file transfers for me.

I just spent about 10 minutes trying to get my laptop to connect to this access point. With 4/5 bars I finally was able to connect to the AP by turning the desired speed down to 11mbps.

I'd much rather see reliability and range improvements over raw speed.

The big thing is HD video streaming - which takes a lot of bandwidth - and for file transfers, well, I'd always like to see more speed. :D

I'm with you there - speed is no good if you can't connect and stay connected!
