Análisis de la Factibilidad Tecnológica en la Agrupación de Canales en Huecos Espectrales en Televisión para la Banda de Frecuencia de 470 Mhz A 698 Mhz en el Caso Colombiano.

Abstract

Colombia has the purpose of using TV White Spaces (TVWS) to connect isolated rural areas. To do this, a legal framework was set up with all the technical and operative conditions in 470 MHz and 698 MHz bands, under a broadband of 6 MHz, where a 25 Mbps broadband should be guaranteed according to the Resolution 5161 of 2017. In countries such as United States, United Kingdom, and Canada, the TVWS administration varies regarding its own regulation. In some cases, the database administration is operated by a third party or government entities. The 802.11af standard provides an international framework that fits into different TVWS regulations for those channels established under 54 MHz and 790 MHz bands, in addition to the 808.22, being a cognitive wireless regional radio standard that operates between a 6, 7, or 8 band, according to the country’s regulations. Three manufacturers (ADAPTRUM, REDLINE, and REDWIN) have been considered for Colombia that meet the requirements to operate the TVWS, assuring the technical and operational regulations.
