| description | This paper presents a characterization of the wireless transmission of biomechanical signals in an embedded system, where a TCP protocol is used in an IEEE 802.11 communications network (Wi-Fi). The embedded system under study, called Imocap, allows the collection, analysis and transmission of biomechanical signals in real-time for various applications, among which the analysis of the movement of the lower and upper extremities and the operation of various control systems stand out. To accomplish this, Imocap is equipped with a Wi-Fi transceiver module (ESP8266) and various input and output peripherals. The wireless communication performance of Imocap, exposed in this paper, was analyzed through different tests in miscellaneous conditions like indoors, outdoors and in the presence of interference, noise and other wireless networks. The different test protocols conducted result in the Imocap system: 1) has a maximum effective range of 45.6 m when in Access Point mode; 2) has a maximum effective range of 44.3 m when in Station mode. In indoors and under the same conditions, the Imocap system: 3) has a maximum effective range of 81.25 m2, either Access Point or Station mode. The results showed that the transmission of biomechanical information through Wi-Fi using the TCP protocol is efficient and robust, both indoors and outdoors, even in environments of radio frequency interference. The use of this protocol is emphasized since its use allows the transmission of packages to be carried out in a controlled manner, allowing the error handling and recovery. In this way, it is possible to carry out efficient and robust wireless communication through embedded and portable devices, focusing mainly on areas such as medicine, telemedicine and telerehabilitation. |

Este artículo presenta una caracterización de la transmisión inalámbrica de señales biomecánicas en un sistema embebido, donde se utiliza un protocolo TCP en una red de comunicaciones IEEE 802.11 (Wi-Fi). El sistema embebido en estudio, denominado Imocap, permite la recogida, análisis y transmisión de señales biomecánicas en tiempo real para diversas aplicaciones, entre las que destacan el análisis del movimiento de las extremidades inferiores y superiores y la activación de diversos sistemas de control. Para este fin, Imocap está equipado con un módulo transceptor Wi-Fi (ESP8266) y varios periféricos de entrada y salida. El desempeño de la comunicación inalámbrica de Imocap, expuesto en este trabajo, fue analizado a través de diferentes pruebas en condiciones diversas como en interiores, exteriores y en presencia de interferencia, ruido y otras redes inalámbricas. Los diferentes protocolos de prueba realizados dan como resultado que el sistema Imocap: 1) tiene un alcance efectivo máximo de 45,6 m cuando está en modo Access Point; 2) tiene un alcance efectivo máximo de 44,3 m cuando está en modo Station. En interior y en las mismas condiciones, el sistema Imocap: 3) tiene un alcance efectivo máximo de 81,25 m2, ya sea en modo Punto de Acceso o en modo Estación. Los resultados mostraron que la transmisión de información biomecánica a través de Wi-Fi utilizando el protocolo TCP es eficiente y robusta, tanto en interiores como en exteriores, incluso en entornos de interferencia de radiofrecuencia. Se destaca el uso de este protocolo ya que su uso permite que la transmisión de paquetes se realice de forma controlada, permitiendo el manejo y recuperación de errores. De esta manera, es posible llevar a cabo una comunicación inalámbrica eficiente y robusta a través de dispositivos embebidos y portátiles, centrándose principalmente en áreas como la medicina, la telemedicina y la telerehabilitación.
