An "area" defines the shape or extension of a particular item or location.
Within an area means the area inside of a shape, for example, the area of a room.
Out of area or outside of the area means going outside the area of a shape, such as going out of a room.
However, some word phrases are made as metaphors or similes to make readers think of a certain thing. The word area can be made into a word phrase, such as "area of study"... the area being within a particular type of study, such as medicine. Or, "area of expertise" means within a particular type of experience or schooling which makes someone an expert with "expertise". So, if I wrote, "The plumber acted outside of his area of expertise when he tried to diagnose his brother's stomach problem", you'd know the sentence means the plumber had no training as a doctor.
Always look at the whole phrase to determine the context.
"Out of area", depending on the context of how it is used, could mean things like:
