> Note, however, that roaming between APs is a feature of the 802.11 standard; you just need to have all your APs on the same layer 2 (802.x) network, and using the same SSID and credentials. No fancy hardware required, and you can even mix and match vendors. Not exactly. There are extensions to pre-authenticate with an AP (802.11r) for truly seamless roaming without packet drop or delay and for AP controlled roaming (802.11k) where the current AP tells you your options to roam to. This last one is important because the AP has generally better information about the network than the client and because the clients are not that great at managing this. I am sure there are other extensions too, but afaik cheap APs don't implement these.
