Increasing AP strength

[ethutchinson]

We have a WISM 2 running 8.0.120.0 . We support about 37 AIR-LAP1142N-A-K9 APs. It is setup and working fine. I was wondering if there is a way to increase signal strength to increase coverage on certain APs. I am sure there are drawbacks to doing this but I wanted to be sure. The APs in question are working by themselves in remote buildings.

Thanks in advance for any advice.

Sire survey suggest you how you can do.

Put more APs into the site(s) or move the APs.

 As Leo said and or in 'simple terms' , you won't expand coverage with that , you may even reduce it due to clients depending on a transmit-response range when talking to an AP. You need sufficient coverage and 'good cells' and for new installations you need a  site survey.

Like the others have said. Ideally you add new APs. The 1142 are anyway out of support and out of everything, so you can probably pick them up really cheap on ebay or similar, just make sure you have enough AP licenses on the WISM 2. As far as I remember they are fully licensed, so that shouldn't be an issue. 

You can also check the power level per AP, yours might be set to automatic and the controller might have lowered the signal strength on those APs. You can increase them typically by one level without making to many problems in other areas.
