Intel To Include Draft 802.11n In Centrino
filenavigator writes "Intel announced at the Globalcom 2006 Expo that they will be including Draft 802.11n hardware in their Centrino chips. It will be interesting since they said that they will start doing this sometime in the middle of 2007, and the 802.11n standard is not to be finalized until 2008. Additionally Draft 802.11n has been dogged by interoperability problems." From the article: "Although the news caused barely a ripple of reaction in the audience of software and hardware engineers, there are industry analysts who have already warned large buyers of wireless technology to resist the temptation to deploy high-speed IEEE 802.11n devices until the standard is ratified."
aka "802.11n leaves us cold?"

Pretty obvious how this plays out:
* Intel will become, pretty much overnight, what all of these routers have to interoperate with,
* Everyone else tweaks their chipsets to work with Intel,
* Intel's interpretation of the draft standard becomes the standard.
Yeah, I'm quite sure that the IEEE will do something to rock that boat.
Better error correction or use of a transmission method that's more robust when faced with a low signal/noise ratio, possibly. With a directional mic and possibly some filtering software, you may be able to hear shouting five miles away, for example.

Why does everyone always assume that wireless networks are only ever used for internet access? Am I forbidden from running VNC to my desktop from my laptop? Can I not transfer files to my wifi-enabled Archos? Streaming media from my desktop to a TV downstairs?

"Pre-N" was just a fancy marketing ploy be Belkin; their "Pre-N" products was made well before even Draft 1 was released. It is proprietary, and when the 802.11n draft is standardized, will probably not be upgradeable to the standard, and will only be backwards compatible to 802.11g with other wireless devices.
It depends on how well are you able to receive. There's a parameter that is named the receiver sensitivity and that's the lowest power that it can receive and still get the correct data. If you have a receiver circuit with sensitivity of let's say -90dbm and that allows you to reach 0.1 miles, if you have another device that has a sensitivity of -93dbm that will allow you to reach 0.15 miles without changing the transmit power. The sensitivity depends on how noise inmune is your receiver to noise and that depends on the radio standard used.
