A Study on Implementation and Performance Measurement of a Short Distance Wireless Transceiver System with Microprocessor

마이크로프로세서를 이용한 근거리 무선 송수신 시스템의 구현과 성능측정에 관한 연구

In this paper, we realized a transceiver system for short distance communication with a commercial RF module working in ISM band and a microprocessor. Also we measured system performance by transmitting baseband data in a building and then we compared the demodulated 긴ta bits with stored data bits in a PC connected with demodulator. The RF module in the experiments works oかy in the bandwidth, 424MHz - 429MHz. with FM mode. The signal level degrades as the distance between transmitter and receiver increases we measured the signal level and bit error in the building of engineering college of our university. we present the measured data with various locations in the building. and the data may be used in design short distance network in a building.
