Roaming between APs.

[william.ong]

Hi, just would like to verify that does Wi-Fi certified also means that a wireless client can roam between 2 APs from different vendor? Or roaming between APs is a propriatery solution? Tks.

Wi-Fi does not specify the AP to AP communications in any way. If you want to be able to roam, be sure to use the same vendors Access Points.

Cell roaming is not addressed in Wi-Fi or 802.11. If you use products from differing vendors, you may or may not lose data or lose your session when you roam from one AP to another. The problem occurs when in the process of sending data you associate to another cell. If your equioment is all Aironet, the data from the "old" AP is sent to the "new" AP via the ethernet, and then sent to the destination host from the "new" AP. This gives you "seamless" roaming.

As far as the WIFI is concern, there is a interoperability paper that identifies theinteroperability between AP to AP
