“…Its single RF channel can be set as either transmitter or receiver (half-duplex). It has been used in several different applications, such as RF exposure assessment [10], as a testbed for avionic wireless tests [11], as an education tool [12] and to measure WiFi spectrum occupancy [13]. SDR sensitivity is primarily defined by the the number of bits of its ADC.…”

This article reports an SDR (software-defined radio) operating as a receiver for nearfield measurement, aiming at EMC pre-compliance tests. The SDR replaces professional-grade RF instrumentation with benefits, with lower costs. Its software application is based on open-source GNU-Radio, which grants a higher versatility to the signal processing and visualization, requiring a single laptop to analyze the data and control the whole system, in real time. Reported tests used two commercial PCB magnetic field probes, and a proof-of-concept near-field imaging is performed in an L-shaped transmission line at 1100 MHz.

Design of an internet of things based real-time monitoring system for retired patients

The main aim of this article is to design a monitoring center for collecting and evaluating the physiological function of retired patients in nursing homes. The system should be able to collect the information of body heat, heart rate, blood oxygen, orientation, and sleep time in the form of the little bracelet. The evaluating part of the system with the program can be placed into personal computer (PC) which can provide a user-friendly interface and easy managing. The program can display all needed information of the patient from previous days or months in the form of the graphs and the nursing person can have the view of the patient´s physiological health. The evaluation and the collection of the data from each patient are done only on the card and the computer is only a device for live-view and managing. In case of the power failure, the monitoring system will be still operating normally due to the uninterruptible power supply (UPS) in the form of the battery. It means that the system will operate even if the PC is powered off. The system also has several external communication interfaces like wireless fidelity (Wi-Fi), ethernet, and general packet radio service (GPRS) which provides an external connection.
