Concerns Over Increased 802.11n Power Usage
alphadogg writes "Next-generation 802.11n systems promise to considerably improve WLAN performance. But the processing required for the boost sucks up more power than the older 802.11a/b/g networks. Still, many enterprise-class Wi-Fi vendors claim to deliver full 802.11n capabilities without enterprise customers having to touch their power infrastructures. So what gives?"
Actually you're wrong. Cisco makes their own ASICs for their AP's, or at least they did in late 90's early 2000's when I supported their wireless division
You're saying I'm wrong but admitting that your information is ten years out of date. A LOT has happened since then. The whole industry has consolidated and everything is now driven by the consumer AP market. Encryption is now done in hardware even in the cheapest g/n chipsets. These is NO reason to do custom silicon to support any of the features offered by "enterprise" APs.
