Wireless Access Point placement

Hi.

If we physically place two APs next to each other, would that create any issues? If yes what is the minimum distance.

The AP's are for different companies and they don't communicate with each other. They are ther to connect users from two different companies.

Thank you for your feedback.

They should be on different

They should be on different channels to limit interference. If it was me, I'd probably put them 300mm apart, just to provide some RF isolation from RF bleed.

Thanks Philip.

Thanks Philip.

So if they use different channels, there will be no interference between the APs?

Correct.

Correct.

if it's in 2,4 Ghz, use

if it's in 2,4 Ghz, use channel 1,6 or 12 (it's the standard) . you must let 4 channel between your channel and their channel or you will got interference.

Channels 1,6,11 standard

Channels 1,6,11 standard states 25 MHz between channels.

IEEE Std 802.11 (2012), which states "In a multiple cell network topology, overlapping and/or adjacent cells using different channels can operate simultaneously without interference if the distance between the center frequencies is at least 25 MHz

http://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Mobility/emob41dg/emob41dg-wrapper/ch3_WLAN.pdf

14 channels are defined in the IEEE 802.11b direct sequence (DS) channel set. Each DS channel transmitted is 22 MHz wide, but the channel separation is only 5 MHz. This leads to channel overlap such that signals from neighboring channels can interfere with each other. In a 14-channel DS system (11 usable channels in the US), only three nonoverlapping (and thus, non-interfering) channels 25 MHz apart are possible (channels 1, 6, and 11).
