Evaluación de la tecnología WMTS para telemetría médica dentro de una red inalámbrica a 1.4 GHZ.

Abstract

The current degree work was aimed to assess the Wireless Medical Telemetry Service (WMTS) technology for Medical Telemetry within a 1.4 GHz wireless network. Bibliographic research was carried out where the characteristics and necessary parameters used in the medical telemetry network prototype design within a wireless network were analyzed. An electrocardiogram simulator, spectrum analyzer, and signal generator were used to assess the performance of the GE ApexPro CH transmitter device. There were proposed four scenarios: 2 in line of sight (LOS) and 2 without a line of sight (NLOS) caused by the obstruction of a concrete wall (cement and brick) with a thickness of 0.2m. There was an interfering signal with varying powers from -20dBm to 20dBm in both environments. These scenarios were developed in the microwave laboratory and classrooms 302 and 303 at Computer Science and Electronics Faculty. These measurements were made with distance variations from 0.5m to 5m with 0.5m separations. In addition, an antenna that works at 1.4GHz was designed and implemented by using the Ansoft Designer software for the transmission and reception of the signal used in the preliminary WMTS network design. Finally, the simulation and implementation of a primary WMTS network were carried out through LabVIEW software with a GFSK modulation and the use of USRP 2932 cards. The results obtained in this research are based on the device's measurements, design, and implementation of a primary WMTS network, allowing us to determine that this technology is feasible, representing an excellent benefit for patient care and medical personnel.
