Ideal location of the access points in a local area network WLAN
Abstract
when we design networks of wireless communication it is important to know where we locate the points of access (APs) to obtain a maximum performance of the network. Wi-Fi is one of the technologies most used in the networks of computers and your facility of installation has flooded APs cities. This spoils the quality of the services given by the network when reduces the speed of transmission of information for the existence of interferences co-channel and of adjacent channel. This article details the process to continuing for the optimization of the location of the APs in a local area network (WLAN. The method that we will use is that of the discreet gradient.
INTRODUCCIÓN
The development of the technology to fact of the wireless networks a very common tool in our lives. It is normal to find them in public places as restaurants, university campus, terminals of transport, homes and offices. your use is so widespread that one can find commonly among 3 and 10 networks operating in the same place. There exist many factors that affect the ideal performance of a wireless network as the attenuation, distance, the rain, etc. Because of it is suitable to do a design of the network in which we have the minor possible loss and besides the fact that our points of access have a very good coverage [1].
The frequencies at which these technologies are employed are relatively high, 2.4 GHz and 5 GHz, and your lengths of wave are among 6 and 12 centimeters, for what they are waves that can be disturbed easily by small obstacles depending on your materials [1-3].
