Questions[channel](server)

I have a wifi deployment with about 60 access points, currently limited to channels 1,6, and 11. This is a college campus, and the residence halls can get quite noisy, from an rf perspective. We typically have about 30 devices per access point, but the kind of traffic the college students expect to use — hd streaming video/netflix, low-latency gaming, and even some p2p file sharing (though we have severe traffic shaping for that at the gateway) — really eats up air time on the access points, and adding more density or pushing users to the 5Ghz space is proving difficult.

I'm considering breaking with tradition, and using either channels 1,4,7, and 11, channels 1,5,8, and 11, or channels 1,4,8,and 11. The idea is to carefully place it so a channel 1 AP is never near a channel 4/5 AP, a channel 4/5 AP is never near a channel 7/8 AP, and a channel 7/8 AP is never near a channel 11 AP. The extra distance should help reduce the chance of collisions on the over-lapping channels. If done correctly and in conjunction with a few additional access points, it would result in a theoretical 33% increase in available airspace.

Has anyone else tried this? Did it work well? If so, which set of channels did you go with?

Is it possible to increase the network bandwidth between 2 servers on Windows Server 2008 and Windows 7 ?

For example : Use 2 Gigabit NICs on each computer to have 2 Gigabits/sec between 2 machines ?

(I know it's possible to load balance traffic from a computer to a group of others base on MAC or IP address with modes such TLB, ALB, etc. that are using LACP (or not), but I've not found any solution to merge 2 NICs as only one for now ...).

Thanks in advance @ all !

There are many pages on the web advising the use of wifi channels 1, 6 and 11 only, so that your wifi channels don't overlap.

Obviously this makes sense when you only have your network do deal with, but in most urban areas there are now a plethora of other networks, all using the same channels. In my current location there are about 4 networks on channel 6, and a couple on channel 1.

So my question is: What happens when you get lots of networks on the same channel? Do the intelligently share it? It is better to have two networks on channel 6, or one on channel 5 and one on channel 6?

I'm currently setting up RHN Satellite, and all works well. I'm in the process of creating custom channels, since we have certain software which should be available for all nodes of satellite, e.g. puppet, facter, subversion, php (newer version than present in base).

I've tried to find documentation on best practices on this. How should they be set up, how to handle different arch, how to handle noarch packages. How to sync updates to dependencies when updating a custom package in a custom channel (e.g. php is updated, how to fetch all updated dependencies).

The channel management documentation from RHEL (http://www.redhat.com/docs/en-US/Red_Hat_Network_Satellite/5.3/Channel_Management_Guide/html/Channel_Management_Guide-Custom_Channel_and_Package_Management.html) doesn't provide me with enough information on how to solve any of theese issues.

All tips, tricks and information regarding this would be great!
