Hi, we are about to deploy a wireless system for one of our customers and we have a few questions. The AIR-ANT1949 will be used to transfer the signal about 300-400meters to a building with one laptop. Line of sight is "quite good". The AIR-ANT4941 will be for indoor usage only and shouldnt be a problem. Is there something I am missing here or should this be quite straight forward? Thanks in advance for any help.
