wireless bridge point to multi point

[asus zowey]

is the following a good design ?

1572 in the Headoffice with omni directional and 1572s in other building 300 Meters away with directional antennas point at the head office ?

2- can this setup work with autonomous APs and with a WLC ? any benefits with the WLC ?

If you have one other building, then why not use patch on both or do you have multiple buildings your trying to connect?  The 1570's will work and will work with autonomous or with a WLC. It's really up to you if you want to use a controller or not. If you plan on growing and purchasing other lightweight access points, then get a controller. With bridging, you not really loosing any features, when running regular AP's in the office for example, you will benefit having a controller.

Thanks Scott

i have multiple buildings

what would be a good antenna gain for the omni and patch antenna on the buildings ? 

in this setup, what is the expected speed on the wired clients connected to the non-root AP? any speed loss ?

Well, as long as you have line of sight and can clear the fresnel zone, then your good. I wouldn't expect speeds like if you had a fiber connection since there are a lot of variables that can affect the link. Take a look at the available antennas and then reference this link to get you theoretical speeds:

Thanks Scott 

very useful link 

i meant to ask if the speed will degrade by 50% ?

Not really, but if you were like daisy chaining buildings you probably would see a slowdown at the far end.  You just need to see what the negotiated rates are from each bridge as this can provide you with info on what you might see as far as throughout. Wireless is half duplex so that number would be cut in half.
