Abstract
A system and method for selectively enabling and disabling wireless connectivity between cellular or PDA users on-board commercial aircraft having a shielded fuselage, and remotely located wireless access points, while the aircraft is at an airport or airfield. The system and method does not require access to an on-board LAN system of the aircraft. The system includes one or more antennae disposed in the cabin area of the aircraft that are coupled via an RF switch with an exterior antenna mounted on an exterior of the fuselage. The RF switch is controlled by a switch control subsystem, and enables or disables communication between the interior antennae and the exterior antenna. The exterior antenna is connected to the switch via a conductor that extends through the shielding of the aircraft. When the RF switch is in the closed position, cellular or PDA users can connect through the interior antennae and the exterior antenna directly to remotely located wireless access points.
