Concerns Over Increased 802.11n Power Usage

Posted by CmdrTaco on from the omg-my-battery-broke dept.

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?"

  1. Not a significant usage of power by Kohath · · Score: 3, Insightful

    It's like 8 watts instead of 3 watts (not exact numbers). It's not a significant amount of power. That's why you don't need to upgrade your infrastructure.

    I'm not sure how a silly article like this gets published. If it was tons of power, how could they make 802.11n adapters for laptops?

  2. Re:Summary is misleading by hawks5999 · · Score: 3, Insightful

    This could end up being good for the ratification of 802.11n. The spec that gets its power usage down to meet the 802.3af power first, wins.
