I am in the process of deploying wireless nodes for independent health care practices (as some of you may know from my previous posts). I need to implement security mechanisms to satisfy the HIPAA guidelines, which to me says I need encryption (WPA/WPA2) with authentication (RADIUS?). The nodes were already purchased (Cisco 1130AG series), so I am not sure if they will support WPA2. However, I need an inexpensive solution (or network appliance) that will run a RADIUS backend. Any ideas on what equipment I need to accomplish this? Furthermore, I would like to put the WLAN on its own VLAN, however I dont know of any inexpensive routers/switches that will allow me to VLAN and run multiple DHCP scopes. I just started researching, so any ideas would be greatly appreciated.
