The B-Box provides WiFi coverage in areas without such capabilities. B-Boxes can be interconnected to extend area coverage and/or distance between ‘Server’ (e.g. iPad based command units) and ‘Client’ (e.g. target systems). One or two antennas can be mounted on a B-Box allowing to enhance the WiFi coverage and/or devices interconnection. The B-Box is a centralized target control system. B-Box allows to use simultaneously different type of control units.
