PROBLEM TO BE SOLVED: To securely and smoothly supply information meeting a variety of user's demands anywhere and anytime in a mobile environment. SOLUTION: Area repeaters 7<SB>1</SB>(7<SB>2</SB>, 7<SB>3</SB>, ..., 7<SB>n</SB>) are arranged by areas E<SB>1</SB>(E<SB>2</SB>, E<SB>3</SB>, ..., E<SB>n</SB>) and an on-vehicle server 8 is arranged for each subarea S to distribute information related to, for example, the area E<SB>1</SB>(E<SB>2</SB>, E<SB>3</SB>, ..., E<SB>n</SB>) and a subarea S where a user is currently present and information on contents prepared by the areas E<SB>1</SB>(E<SB>2</SB>, E<SB>3</SB>, ..., E<SB>n</SB>), not to mention properties of the user. User terminals 4<SB>1</SB>(4<SB>2</SB>, 4<SB>3</SB>, ...) receive contents etc., by short-range communication through nearby AP repeaters 11 in the subarea S, and then information meeting a variety of user's demands is securely and smoothly provided anywhere and anytime in a mobile environment.
