In the last post I covered how the Airport Safety Self-Inspector has to be in more then one spot at a time, and how this could lead to problems. The Airport operator wants to minimize the amount of time the safety inspector is not on the field and to do that I said wireless communication would be a possible solution.
The question then becomes what does this type of system look like. The graphic below provides a good answer to this question.
As you can see there is the main server which hosts the application used to enter Field Condition Reports, and a second computer used by the airfield safety inspector to enter the FiCONs. The two computers talk to each other over a wireless communications network.
For the wireless communications I would recommend using a 802.11(g) network with a large high gain antenna on both sides of the system. One large omni directional antenna for the main server, and a second smaller one for the mobile vehicle.
