Abstract

In December 2011, Colombia updated its national Digital Terrestrial Television (DTT) standard from DVB-T to DVB-T2, the second generation of the DVB (Digital Video Broadcasting) project. DVB-T2 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 its predecessor. The case of Colombia is very special because it was the first country to deploy DVB-T2 with 6 MHz channelization and because the DVB-T2 networks were deployed from scratch without any constraint imposed by existing DVB-T infrastructure. This paper analyzes potential DVB-T2 transmission modes to optimize existing DTT network designs of Colombia, originally made for DVB-T, analyzing the trade-offs between capacity, coverage level and Single Frequency Network (SFN) size. Network planning results has been performed with a professional DTT network-planning tool based on the three first deployment phases of the DTT network of the public national TV broadcaster RTVC. Results obtained fully justify the decision of adopting DVB-T2. Compared with the initial DVB-T design, DVB-T2 can increase the national covered population up to 7.3% or offer 70.2% more of capacity transmission, or increase the SFN size up to 135% keeping the total power transmission and the geographic distribution of the transmitters.

Quality index

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal Ieee Latin America Transactions, and although the journal is classified in the quartile Q4 (Agencia WoS (JCR)), its regional focus and specialization in Engineering, Electrical & Electronic, give it significant recognition in a specific niche of scientific knowledge at an international level.

From a relative perspective, and based on the normalized impact indicator calculated from the Field Citation Ratio (FCR) of the Dimensions source, it yields a value of: 3.47, which indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: Dimensions Aug 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2025-08-15, the following number of citations:

  • WoS: 9
  • Scopus: 11

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2025-08-15:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 11.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 11 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 0.25.
  • The number of mentions on the social network X (formerly Twitter): 1 (Altmetric).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:
