A portable wireless communications adapter comprising: a wireless antenna and wireless access point electronics configured to communicate wirelessly with a portable electronic device; a wireless receiver configured to receive Wireless Avionics Intra-Communication, WAIC, communications over a WAIC frequency range between 4.2 gigahertz, GHz, and 4.4 GHz; a wireless transmitter configured to send WAIC communications over the WAIC frequency range between 4.2 GHz and 4.4 GHz; a location sensing module configured to: determine a location of the portable wireless communications adapter relative to an interior of an aircraft based on WAIC communications received at the wireless receiver ; selectively enable the wireless transmitter to route data between the portable electronic device and one or more systems and/or sensors of the aircraft by sending WAIC communications to the one or more systems and/or sensors of the aircraft in response to determining that the portable wireless communications adapter is located within the interior of the aircraft; and selectively disable the wireless transmitter to prevent routing of the data between the portable electronic device and the one or more systems and/or sensors of the aircraft by preventing the wireless transmitter from sending WAIC communications to the one or more systems and/or sensors of the aircraft in response to determining that the portable wireless communications adapter is not located within the interior of the aircraft. a wireless antenna and wireless access point electronics configured to communicate wirelessly with a portable electronic device; a wireless receiver configured to receive Wireless Avionics Intra-Communication, WAIC, communications over a WAIC frequency range between 4.2 gigahertz, GHz, and 4.4 GHz; a wireless transmitter configured to send WAIC communications over the WAIC frequency range between 4.2 GHz and 4.4 GHz; a location sensing module configured to: determine a location of the portable wireless communications adapter relative to an interior of an aircraft based on WAIC communications received at the wireless receiver ; selectively enable the wireless transmitter to route data between the portable electronic device and one or more systems and/or sensors of the aircraft by sending WAIC communications to the one or more systems and/or sensors of the aircraft in response to determining that the portable wireless communications adapter is located within the interior of the aircraft; and selectively disable the wireless transmitter to prevent routing of the data between the portable electronic device and the one or more systems and/or sensors of the aircraft by preventing the wireless transmitter from sending WAIC communications to the one or more systems and/or sensors of the aircraft in response to determining that the portable wireless communications adapter is not located within the interior of the aircraft. determine a location of the portable wireless communications adapter relative to an interior of an aircraft based on WAIC communications received at the wireless receiver ; selectively enable the wireless transmitter to route data between the portable electronic device and one or more systems and/or sensors of the aircraft by sending WAIC communications to the one or more systems and/or sensors of the aircraft in response to determining that the portable wireless communications adapter is located within the interior of the aircraft; and selectively disable the wireless transmitter to prevent routing of the data between the portable electronic device and the one or more systems and/or sensors of the aircraft by preventing the wireless transmitter from sending WAIC communications to the one or more systems and/or sensors of the aircraft in response to determining that the portable wireless communications adapter is not located within the interior of the aircraft. <EOS>
