Location Accuracy Airwave

Hello

As far im reading for a good localization 3 APS must see the client

But that make me think that  if one AP is serving a specific client, and there are 2 more APs near, they are serving clients in Other channels which means that it should not see the first client of the first AP.

 

As far i remenber the AP even if its serving clients it goes out of his channel to check other channels, so the 2 APs that are serving on other channel should see the  client on  which on the other AP

For example

AP 1 got one client ( client Z)which is on channel 36

AP 2 is on channel 40

AP 3 is on channel 44

 

By now just AP 1 can see client Z

but when the AP 2 goes out of the channel 40 it start looking to see what he can see on other channel but just for a momment which is really fast...

 

Now that makes me wonder about the accuricity doing that?

 

It is much better having one AP on Air monitor for example

 

AP 1 got one client ( client Z)which is on channel 36

AP 2 is on channel 40

AP 3 is on channel 44

 AP 4 is on air monitor

Will having the AP 4 in air monitor that can also see the client Z on channel 36 is much better choice for accuracity of the location?

When you really need the client location to be really good it is recommended having an ap as air monitor? or this wont help to make it more accurate?

 

Anyone ? :)  Rob? :)

 

Cheers

Re: Location Accuracy Airwave

I'm sure that dedicating an AM every so often will certainly improve accuracy and IDS functionality.

 

I'm also pleased to report that the accuracy is high enough, that our technicians occasionally call me to see where they left the bar-code scanner, or portable printer.

 

The real requirement for accuracy is density - whether AP or AM or some combination of both. We have floorplans in the 100K-150K square feet range and have 12-15 iAP105 for that area, we get a 7x7 gridsize in Airwave and are pretty happy with accuracy.

 

I also have a yard in the quarter-mile-on-a-side range with 50x50 gridsize and 8 AP60 with somewhat poorer accuracy (terrible)

Re: Location Accuracy Airwave

Are you using air monitors? or you got APs on normal mode?

Re: Location Accuracy Airwave

I suppose I could have been clearer, couldn't I ;)

 

We have all access points in "normal" mode.
