We are looking at deploying wireless networks in our offices globally. From what I understand, we'll be using WPA2 Security. From what I understand, users will have a seperate username/password to log onto the wireless networks from their laptops and mobile devices (Blackberry, iPhone, Android etc).
I'm a little confused about the security aspects of this in terms of RADIUS and certificates. Since we are using usernames and passwords, presumabley with the help of a RADIUS server, are certificates also going to be involved? Or are certificates only involved if we're NOT using usernames/ passwords.
Secondly, if we are using certificates (either with RADIUS or not), how do we get the certificates onto laptops and mobile devices?
Finally, it's the mobile device side that I'm most worried about. Has anyone any advise regarding getting Blackberry, iPhones and Androids to work with Enterprise WPA2?
Many thanks in advance, folks.
