We have a customer is a hospitilized environment.
Since two months they work full time with the new Dutch Electronic Patient Dossier.
We installed 3 Cisco 5508 controllers, version 7.0.230.0 last year on a HP-switched network on a layer 2 mobility domain.
Cisco 1041 AP are
The personnel works woth thin clients (http://www8.hp.com/nl/nl/products/thin-clients/product-detail.html?oid=5226831 The one with the double antenna.
This client has a Broadcom BCM943228HM4L 802.11 a.b.g.n (2x2) adapter.
On the client they have a connected RDP session to a server with the documents.
Now they are walking from one patient to another patient.
The problem they experience is a very late roaming.
At the beginning of the corridor, the client will associate, but is going to roam at the end of the corridor.
We installed 4 AP's on each corridor, so they signal is very well, maybe to well?
I disabled client loadbalancing and band select.
The lowest data rates are also disabled. Mandatory begins at 12 Mbps. I can increase this to 18 Mbps.
These clients work with PSK, with both methods (WPA-TKIP and WPA2-AES) enabled.
We did this because of many old and new clients.
The customer tried to find out the problem with a smartphone, same issue. Very late roaming.
I can upgrade the WLC to 7.0.240.0. The only problem I have is the WCS. When upgrading to 7.2 and higher I need to have NCS.
I don't know why they sold a AP1041 in stead of AP1042.. I think a price issue.
Thanks.
Regards,
Erik
