wifi and pdas

[flewio7777]

Hi all,

a customer told me that he has bad quality of wifi when use PDAs in a zone.  He has AIR-WLC2125-K9 controller, AIR-AP1242AG-E-K9 APs ( upgrated to

lightweight) and native APs AIR-LAP1242AG-E-K9, 5dBi antennas.

He suggest to make a big "wifi cell" made of 4 APs so no roaming is need, is it possible with cisco ? I know that is possible with other vendors.

Is there some specific configurations for PDAs ?

How can understand if there is some bad configuration or bad position of Aps, ecc ?

What logs o values can help me ?

Any ideas ?

Thanks a lot

I did not understand the issue!! do we need roaming or not?? do we need to deply the APs in such a way that the roaming happens with ease while using PDAs??

Hello Surendra.

If is it possible, we want to select some APs that cover a specific area of building (where employees use PDAs and move quickly) and manage them as single wifi cell, so we suppose that no roaming happens and improves the quality for PDAs.

What do you think about ?  Or do you have some ideas ?

Regards.

just to clarify, the PDAs are "barcode scanners".

so we suppose that no roaming happens and improves the quality for PDAs.

This, unfortunately, doesn't make any sense and contradicts itself.  As I'd like to call it, it's so wrong in so many levels.

Firstly, one of the main selling points for getting a controller-based wireless network in comparison to autonomous APs is roaming.

Item in RED:  Yes.  It's possible. 

Item in BLUE:   Yes and no.  If we are still talking about controller-based then this is a definite YES.  But if we are talking about autonomous IOS this depends if you configure WDS.

a customer told me that he has bad quality of wifi when use PDAs in a zone. 

Most likely because there's not enough WAPs to cover dead zone.  This happens alot when the actual layout changes while the WAPs weren't redeployed.

If this is the case, I'd consider redeploying the APs to cover this "zone" or get more APs (if the WLC can still support).
