PROBLEM TO BE SOLVED: To provide a system which makes it possible to freely obtain necessary information and freely purchase a polling ticket everywhere in a stadium. SOLUTION: Base stations A, B, and C are arranged in all the areas in the stadium and data information is transmitted between portable terminals 1 to 3 and a central control processor 4 by radio through the base stations. The portable terminals 1 to 3 send specific data to the central control processor 4 through the base stations and the central control processor 4 returns information corresponding to the sent data to the portable terminals 1 to 3 through the base stations. Consequently, necessary information can be obtained and a polling ticket can be purchased everywhere in the stadium. |
