Running wireless with just channels 1 and 6
Hi All, looking for some advice on a potential configuration change in our wireless setup. We are currently running a Cisco 4404 wireless LAN controller with over 70 APs spread over 3 campuses (a mix of 1131 and 1231 APs). Channels are automatically assigned by the WLC and this system has been in place for around 7 years and worked well up to press.
Due to some recent building renovations a door control system has been introduced that uses wireless technology for the access control readers. The manufacturers guidelines state that channel 11 should be reserved for their door control APs. We have implemented this system in one building so far and I have manually fixed the 4 Cisco APs on either channels 1 or 6. If the system is rolled out further I can make a global change on the WLC to only use channels 1 and 6 for dynamic allocation. However, I am uneasy about doing this as I believe it will significantly impact the existing wifi network. As we do not have Cisco Wireless Control System I am unable to produce any reports to verify my concerns, and I am trying to make a sound case to management why this might not be a good idea.
Can anyone throw in their technical expertise and share their thoughts on running a 2.4GHz wifi solution with just channels 1 and 6?
