This document discusses the implementation of a wireless communications system to monitor and control the buoys of the access channel, since in Colombia in the coastal part it has the blessing to have access to two oceans that control a valuable source of communication and transport with the whole world, maritime resources and transformations, in such a way that strategies have been created to convert the oceans in an optimal and sustainable way into essential sources of economic and social development, and to protect protection, integration and the national maritime progress that also allows to impact coastal areas, where some of the poorest municipalities in the country are located. In this way it is desired to implement a communications system that will keep a constant watch on the operation of the devices where the simulation of a mesh network is performed using ZigBee transmitters that has the ability to transmit and receive wireless signal at a frequency of 2.4 GHz at 1200 meters to the line of sight in ideal working conditions. Zigbee is a technology that allows the deployment of wireless networks based on solutions of low cost and consumption, the main objective is secure communications with low shipping rate and changes the life of your batteries.
