Investigación y diseño de la arquitectura de red con tecnología 802.16 en convergencia con 802.11 para mejorar la QoS de sistemas digitales inalámbricos en Fastnet Cia. Ltda.

Abstract

This work involved the network architecture with WiMAX technology on convergence with WI-FI research and design in order to improve the quality of digital services and bandwidth to FASTNET Cia. Ltda. Customers, located in Riobamba city, a scientific investigation with these technologies was carried out, and different equipment containing these wireless features was chosen allowing the implementation of services such as video surveillance and internet access to satisfy customer demand. A survey to find out the current situation of internet access service offered to corporate customers was performed and to demonstrate the research facility. LINKPlanner planning software and Mobile Radio were used, thus simulating the network links point to multipoint topology through LOS and NLOS programing, operating in licensed frequency of 3.5 Ghz. and exporting simulations to Google Earth containing actual maps and topography suitable for network architecture. For customers who require Video surveillance Services, the modulation applied to the CPE is 64 QAM-MIMO B, which provides a throughput of 61.65 Mbps of which 15 % is destined for Down Link, so that 9.32 Mbps and 52.32 Mbps to Up Link approximately. To corporate internet access services has a 16 QAM-MIMO B modulation, which will give a throughput of 35.64 Mbps of which 85% is destined for Down Link, so that 29.49 Mbps and 6.14 Mbps for Up Link approximately. We conclude that WiMAX is ready to support traffic services produced by Video surveillance services and Internet access, it is recommended to FASTNET consider costs involved in the implementation of this design.
