In this study, 4 channel biotelemetry device was designed and implemented for monitoring physiological and biological signals of the patients at indoor. Body temperature, respiratory rate, heart rate, electrocardiogram (ECG) and electromyogram (EMG) signals were transmitted using 10 mW 433 MHz and 500 mW 868 MHz FM/FSK transmitter with 9.6 Kps transmission speed. At indoor, receive signal strength indicator (RSSI) levels were measured and compared with 433 and 868 MHz carrier frequency. The placement of repeater at indoor was decided as a result of RSSI measurement.
在本研究中，设计并实现了一种4通道生物遥测设备，用于在室内监测患者的生理和生物信号。体温、呼吸频率、心率、心电图（ECG）和肌电图（EMG）信号通过传输速度为9.6 Kps的10 mW 433 MHz和500 mW 868 MHz调频/移频键控发射机进行传输。在室内，测量接收信号强度指示（RSSI）水平，并与433和868 MHz载波频率进行比较。根据RSSI测量结果确定了室内中继器的放置位置。
