[edit] Cumulative list of billionaires

The article you created, Cumulative list of billionaires appears to be a cut and paste copy of List of billionaires. What are you planning to do with it? Delicious carbuncle (talk) 21:31, 2 April 2008 (UTC)

[edit] 802.11a

Hi, thanks for your comments looking to improve Wikipedia's accuracy. It took me a bit to figure out what you were referring to, but the chart was actually on this page {{Wireless Networking Standards}}. The numbers are actually fairly accurate (and a bit conservative, IMO) as 802.11n adds in MIMO or multiple physical antennas on both the base station and the client. This simple concept has the interesting feature of allowing more range at higher speed due to the way the different waves propagate. (A simple explanation: Note that 2.4Ghz/SpeedOfLight means each full wave is about 12.5 centimetres (4.9 in) long, so by spreading two antennas out merely six cm means the wave is twice as likely a wave to be at full amplitude when it reaches the client). Furthermore 802.11n improvements encompass both 2.4GHz(b/g) and/or 5GHz(a), though most cheaper draftN equipment seems to be 2.4G only.

Also, if you have any more questions, feel free to respond right under here. As you'll be on my watch page for a few months. -- KelleyCook (talk) 15:59, 30 May 2008 (UTC)


Thanks for the quick response. If I understand you coreectly you´re saying instead of using a 12 cm wave but make it in 2 merely 6 cm waves it has more probablity to reach it´s destination.
I always tought that the shorter the wave the less probability it has cover a long distance. For example a 700Mhz wave (42,9cm) has far more reach than a 5,8Ghz wave (5,2cm).
Or are you just saying in any MIMO case; If you have 2 antenna's there is always a 100% bigger probablity that you are reaching your destination? -- Iberned (talk) 19:54, 03 June 2008 (UTC)
