Implementación de un prototipo de una red auxiliar de comunicación por radiofrecuencia con nodos basados en dispositivos electrónicos y equipos móviles para mensajería instantánea.

Abstract

The present investigation consists of designing and implementing a prototype of an auxiliary network of communication by radiofrequency with nodes based on electronic devices and mobile equipment for instant messaging, the prototype works with Arduino Pro Micro and the NRF24L01 module, for wireless communication by radio frequency. An instant messaging application performed in Android Studio for mobile devices made, it is easy to use for any type of user to send and receive text help messages. The operation of the auxiliary network of wireless communication does not require additional infrastructure to perform the communication, due the device created transmits and receives the data by radio frequency. The tests carried out, determined the communication between devices reaches approximately 238 m. in a line of sight, while with obstacles it is approximately of 18m, with a transmission time and reception of a second independent of the distance. It concluded the implemented prototype is a low consumption device, it fed on since the mobile device that can become a helpful tool mainly in natural or provoked disasters, that they have generated collapse of communication networks. The research paper recommends that when improving the prototype transmission and reception of voice, data, and images apply, besides, to perform studies to incorporate the data transmission by radio frequency in mobile devices.
