RB750GL + Radius

Hi, first of all sorry poor english and if this is not the right place for this kind of question, I´ll be really grateful if you could help, I am really new to Mikrotik, I need a livel 5 license to RB750GL to support more than 20 simultaneos sessions in radius, I´ll order a license in mikrotik site but I am not sure if I need a level 5 license to RB750GL where Radius (user-manager) is installed or the hEX where the DHCP is installed

thanks a lot
