We've set the wireless on our prototype mobile unit to use the http://routerboard.com/RB911G-2HPnD. On the base we've used the http://routerboard.com/RB951G-2HnD connected to either the https://www.ubnt.com/unifi/unifi-ap/ or https://www.ubnt.com/unifi/unifi-ap-outdoor/ as we need the antennas. All using mostly the basic setup out of the boxes.
We'd like to do all of this with Mikrotik equipment, so something like one http://routerboard.com/RB911G-2HPnD at the base and one at the mobile unit. My concern here is interference and range. These could be in a venue with 10,000 people or 50,000 for that matter so we need them to work without any input. And also have a semi decent range.
I have fairly basic wireless knowledge so would be grateful of some pointers. Would also be happy to hire an expert to assist once we've got the basics sorted.
