Wireless solution equivalent to Watchguard's AP320?

[beastylemon]

Hello,

WatchGuard has a wireless AP called the AP320.
These have the capability of a seamless hand-off to the nearest access point.

For example, you have 5 AP's spread throughout a large office under the same SSID, and depending on your physical location, you are always connected to the closest AP, and when you move throughout the building pfSense handles the hand-off between AP's seamlessly.

Does pfSense have anything like this?
