Frequency and Network Planning and Optimization of the Digital Terrestrial Television DVB-T2 Networks in Colombia

Abstract

[EN] In December 2011, Colombia updated its national Digital Terrestrial Television (DTT) standard from DVB-T to DVBT2, the second-generation European DTT standard. DVBT2 is the current state-of-the art DTT system in the world, and it brings very significant improvements in terms of capacity, robustness and flexibility compared with any other DTT technology. The iTEAM Research Institute was very involved in the promotion and adoption of DVB-T2 in Colombia. The case of Colombia is unique because it was the first country to deploy DVB-T2 with 6 MHz channelization, and because the digital networks will co-exist with the analogue NTSC network until the analogue switch-off and with digital ISDB-Tb and DVB-T networks in the neighbor countries. Furthermore, DVB-T2 networks will be deployed from scratch without any constraint imposed by existing DVB-T infrastructure. This paper provides an overview of the frequency and network DVB-T2 planning activities performed by the iTEAM Research Institute in cooperation with the Spectrum Regulator of Colombia.
