The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

802.11N Overlapping Channels

Asked by jimbecher in Wireless Technologies

  Unless I am doing something incredibly stupid (which has been known to happen) I find the range of 802.11n in the 5GHz band so limiting it is almost useless either indoor or outdoor. So the brief question is have I done something incredibly stupid or is everyone finding the range in the 5GHz band to be very limited?

   So assuming it isn't just me :) I am back to the 2.4GHz band. The specific application is outdoor WDS. There are only 3 non-overlapping 22MHz channels in the 2.4GHz band. The first obvious question is will the 40MHz channel with work in the 2.4GHz  band and if so that would force the use of overlapping channels would it not?

   Would I be better off not using the 40MHz width or letting it us the 40MHz width and putting up with what ever degredation is caused by using overlapping channels?

   Lastly ... when setting the channel on the AP and using 40MHz channel width does it really make much difference what channel I set it at? Is channel 6 as good as any and does the AP at that point figure out which other channels to use to get the 40MHZ width?
