Diseño de una red inalámbrica con tecnología MIMO TDMA, para proveer del servicio de internet en las parroquias rurales del Valle de Los Chillos.

Abstract

The evolution of technology has generated a greater competitive rivalry among Internet service providers, therefore, the goal was to design a wireless network to provide Internet service to rural areas of Valle de los Chillos and accessible prices , under the Wireless last mile access topology. The documentary methodology was applied to carry out the market, technical and economic study of the proposal, whose results showed that the projection of the demand with real data, under the interpolation of a logarithmic function, resulted in a considerable number of users, being the main characteristic of MIMO, the Three-Stream that uses three flows of spatial beams to increase in a remarkable way the wireless speed. Also very important is the channel width, normally 20 MHz, but 802.11n allows 40 MHz channel widths using two separate 20 MHz channels to increase the minimum transfer speed 177.5 Mbps, requiring MIMO with 2 channels of 20 MHz each for Maximum speed of 300 MHz and 300 Mbps theoretical speed in WiFi-N must have at least MIMO 2T2R, 40 MHz channel width and two beams (two-stream), with 20MHz channel bandwidth, 2.4 GHz or 5GHz. In conclusion, the last mile access topology improves the connectivity of the proposed wireless network.
