Checking the website of airties might help. I guess they can help you if you tell them about your needs. They sell adsl modems, access points (for indoor and outdoor usage)If the complex is not very big you can even do it yourself with a little help. The idea you have an adsl modem and access points to form your wireless local network.
After-sales service of the company is great. You can either buy the equipment and do it yourself or you can work with one of the dealers in your area.
