Paper Abstract

This paper gives a short description of a low cost communication device. The wireless intercom devices presented here enable communication between any two of these products through specialized synchronization options. This communication system consists of two functionally linked radiofrequency intercoms in the 2.4GHz free band. Each of these devices consist of a hands-free cellular system containing a microphone and a loudspeaker, which is connected individually to each communication device through a plug of four (4) contacts and three point five (3.5) mm in diameter, it also has a single USB connector for battery charging (without data bus), which is made of a lithium polymer, and finally three (3) buttons from where certain functions are controlled: volume level, audio filters, on, off, among other.
