Warehouse with Cisco Wireless (WLC) and Datalogic scanners

[Snorre Oelberg]

Hi.

Is there anyone who have experience to share regarding tuning Datalogic Scorpio clients to use with Cisco Wireless?

We have a WLC2504 with 40 CAP2702e with Air-ANT2560P4W antennas ceiling-mounted.

RF-scans come out greate. Laptops works perfect. But the handheld devices like Scorio and truck terminals responds with low coverage and roams very slow. They use Embeded Windows or CE with Summit as supplicant.

Please advice

Hi,

1.Did you already disabled low late in 2.4Ghz and 5Ghz on WLC?

2.Did yo already configured device manager on Embedded Windows? 

3.Could you confirm the WiFi approved standards on handheld?

   Maybe your handheld device is only work with "802.11". (not a/b/g/n, just "802.11", it can only use with 2Mbps)

I would start with "layer 1" here. Your post-deployment site survey should include:
1. Signal strength and SNR with the scanner as client in mind
2. Channel overlap / co-channel interference
3. Channel utilization
4. Used channels

All of the three points should be tested for both the 802.11b/g/n and 802.11a/n/ac frequencies. When this information is clear and matches up with your requirements you can check your client (configuration). Which bands and channels can it use and prefers it? What is the roaming threshold and how does that look like in real life? Any software updates available?

Next step could be using a open and encrypted test network to rule out any keying / dot1x issue. If there is still no joy you need to make wireless captures and see what is happening in the air.

Please look useful posts... :-)
