Enlace inalámbrico de dos edificios

Abstract

Due to changes proposed by the actual government, Central Bank of Ecuador’s CEO relocated staff of the Recovery and Liquidation of Closed Banks department that worked in the main building of the institution, which is located in the intersection of 9 de Octubre Ave. and Pichincha St. With this requirement, System Engineering and Communications staff was asked to give the proper technic solution in the way that it maintains the same level of quality of service that the relocated staff needs. Physical optical fiber link was discarded because of the existent difficulties of the banking zone, where both buildings are located. The best option was to implement a wireless link, considering that a line of view and unsaturated available frequency was existent in this zone. After defining the device that best adjust to the requirement, which considered: quantity of users, transactional systems, internet access, institutional email, which the staff must keep using; required answer time, wireless link security and transmitted information security; the staff proceeded to make the field tests and penetration tests that confirmed the quality of the service that the staff were experiencing with an acceptable answer time. The system was implemented to link the 4th floor of the Central Bank main building (Data Center,) with the 11th floor of the Ex Previsora building, for later implement a second ling between Data Center with the 16th floor of the Ex Previsora building, this justified by the staff increment. Both links were configured as crossed backup in case of failure of either of the communication devices.
