Determinación técnica de los mapas de cobertura de las redes IEEE 802.11 dentro de los bloques 1,2,4, y 6 de la universidad Santiago de Cali, sede pampalinda

Abstract

The Santiago de Cali University has a wireless WI-FI®-LAN communication network system, which is a mixed combination of two types of networks: WI-FI® , which is a wireless technology that allows the connection of electronic devices, LAN (area networks local) that connects devices via data lines or telephone lines. The backbone network interconnection or backbone connections is composed of a large number of switches between the 7 buildings that make up the Santiago de Cali University, this connection has a speed of 10Gbps per second and between classrooms has a speed of 1Gbps per second to the consumption of users who have terminal devices (cell phones, computers), their accessibility (AP) has an estimate of 300 Ap to be used by approximately 3500 to 4000 students a day and approximately 100 administrative. The wireless communication network of the Santiago de Cali University, is within the minimum parameters established by the IEEE standards (Institute of Electrical and Electronic Engineering), to offer the connectivity service to the educational community, but the communication offer presents problems which are evidenced in the repeated complaints of the users such as: connection difficulty, data transmission, coverage. Therefore, to give a general approach of how the state of the wireless communication network is, a “Technical Determination of the Coverage Maps of the IEEE 802.11 Networks within blocks 1,2,4, and 6 of the Santiago de Cali University, Pampalinda Headquarters.” was made through the implementation of the Inssider Home software Ekahau HeatMapper that allowed the mapping of the coverage of the electromagnetic spectrum that is used to evaluate in graphs the internet band that is analyzed and the flow of data packets. The conclusions obtained showed that there are problems in the connectivity of the devices and in the data traffic that cause a decrease in the signal and delay in the transfer of data, possibly due to the fact that there is an Access point that may be damaged, badly located or excessive of networks, the conjectures are many and it is expected that there will be continuity in the investigation.
