In this paper, we propose a personal-computer-based wireless data access system, which used direct sequence spread spectrum method and the ISM band with 2.44GHz radio frequency. By applying bi-directional transmission between wireless handy terminals and PC or servers, it can be effectively connected with any kinds of database systems such as Oracle, MS-SQL and Access. Therefore it could economically be used as peripheral equipments for ERP or SCM system.
