A wireless communications system suitable for use within an aircraft, such
as a part of a wireless emergency lighting system (WELS) is provided. In
an aircraft, EXIT signs are located throughout the interior of the
aircraft, including the ceiling (general illumination), seats (floor
proximity) and EXIT doors (locator/identifier). A wireless communications
system uses an integrated lens antenna system that takes advantage of the
quantity and location of emergency lights such that any given light will
have a direct radio frequency (RF) path to several other lights. A
virtual network can be created such that if the path between any two
lights becomes disrupted, alternate paths will be constructed under
software control.
