Abstract
In this paper, we propose a wireless data access system, which used direct sequence spread spectrum method and the ISM band with 900MHz radio frequency. By applying bi-directional transmission between wireless transmitter and receiver, it can be effectively connected with any kinds of RF-ID with 900MHz ISM band. Therefore it could economically be used as peripheral equipments for RF-ID system.
본 논문에서는 900MHz의 ISM대역에서 사용가능한 통신방식 중 직접확산방식의 무선데이터 송수신 시스템을 제안
