Need Help for wireless setup

Hi all,

I have a customer who has his own cybercafe and also is distribting internet to his local residential users.
Now this customer wishes to give the last mile connectivity to his local users using wireless. They are spread aroung 1km wide from the central location.

i saw this product on the mikrotik site
http://www.mikrotik.com/Documentation/rb_om18.pdf

what i interpret from this is that this will have one 5.4g antenna which i typically would use for backbone connectivity (not at the moment, but at a leter date when he wishes to extend his wireless reach), the other 2g antenna i can use to give connectivity using 802.11a/b/g standards.
Please correct me if i am worng on this.
my major query is what will be the range for both of the wireless interfaces if i have a clear LOS and in case of NLOS (LOS=Line Of Sight, NLOS=Near Line Of Sight)

If this is not the proper product, can any body suggest me a proper solution, the customer alread has a 2.7 mikrotik with level 4 license.

Tnahks in advance
