We’ve recently switched one of our sites to the new pepwave ap-one in-wall’s from an older cisco/linksys business wap line. The new setup is very slick – very easy to deploy and manage. However I’ve got what could only be described as a challenging wifi environment and I’m looking for advice on the right channel assignment strategies for my equipment/environment combination.
I’m deploying wifi on a ship which is almost entirely made of metal – the metal obviously is not particularly great for RF – so we tend to have a fair number of WAPs relatively close together to service different areas of the ship – with signal strength varying significantly as bulkhead doors are open/closed for various reasons. For this reason, the ap’s are deployed relatively close to each other.
A few questions:
It’s not all that clear to me the best choice for AP channel assignment … Via the balance WLAN controller I can specify for each ‘profile’ either a specific channel or ‘auto’ with a set of channels – what’s the right choice for an all-pepwave with wlan controller managed environment? Historically from my experience with other products the ‘auto channel assignment’ algorithms were never particularly effective – so it was wiser with our previous ap’s to manually assign the channels to try to achieve the most frequency separation between the nearest/most interfering access points … But I’m wondering if ‘auto’ assignment as implemented in the balance wlan controller is appropriate for my environment now… It seems to me like the algorithm for channel assignment could be ‘much more right’ than what could be achieved in the past with non-centrally managed ap’s …
I only have and only need a single profile for all the ap-one’s hanging off my balance router – if I do need to do manual channel assignment for each AP how do I do that – do I end up having to make a different profile for each AP?
Same questions regarding dynamic power adjustments … It seems like power=dynamic:auto is appropriate for an environment like mine with a significant potential for ap-crosstalk … Also – if I choose to enable Power=dynamic:manual or Power=dynamic:auto, I am also able to set an option called ‘coverage redundancy’ with values ‘high, medium, or low’ … Are there any details on what the coverage redundancy setting does? – I can’t find it described anywhere in the manual …
What does the ‘preferred frequency’ option do? I thought it was essentially controlling ‘band steering’ until I noticed the ‘band steering’ setting specific to each SSID …
I’ve been operating with a profile configured with dynamic channel assignment and power:max for awhile now … I notice that the AP’s are changing channels frequently – usually once or twice a minute in an environment with 4 AP-one’s … Is this the auto-channel algorithm moving the channel conflicts from ap to ap in some infinite game of ‘pass the interference’ …?
