Portable wireless communications adapter

A method comprising:

• establishing, using a wireless antenna and wireless access point electronics of a portable wireless communications adapter, a wireless communications session with a portable electronic device for wireless communications between the portable wireless communications adapter and the portable electronic device;
• receiving, by a wireless receiver of the portable wireless communications adapter, Wireless Avionics Intra-Communication (WAIC) communications over a WAIC frequency range between 4.2 gigahertz (GHz) and 4.4 GHz;
• determining, by the portable wireless communications adapter, location of the portable wireless communications adapter relative to an interior of an aircraft based on the WAIC communications received over the WAIC frequency range;
• selectively enabling a wireless transmitter of the portable wireless communications adapter to send WAIC communications over the WAIC frequency range corresponding to wireless data received from the portable electronic device via the wireless communications session in response to determining that the portable wireless communications adapter is located within the interior of the aircraft;
• and
• selectively disabling the wireless transmitter to prevent the wireless transmitter from sending WAIC communications over the WAIC frequency range in response to determining that the portable wireless communications adapter is not located within the interior of the aircraft.
