“…The coexistence of DTT and LTE signals that are deployed in Colombia and in the South American region has also been taken into account, [16][17]. In another way, in Colombia different types of transmission have been carried out due to technological changes looking for which one can be adapted according to geography, [18][19]. In the same sense, there have been discussions of the policies that seek to regulate the transmission of DTT, [20][21].…”

This paper analyzes the Digital Terrestrial Television (DTT) signal coverage in the department of Cundinamarca, comparing two propagation models: Okumura-Hata, and Stanford University Interim (SUI). These models were selected because they allow the calculation of propagation losses in the UHF band and do not require greater precision in the cartographic information to estimate diffraction losses. As a result, was obtained that the selected models are close to the field measurements, in a range of 8 to 12 dB. In addition, adjustments were made to the propagation models obtaining the losses estimation in the signal propagation. The models were evaluated applying statistical criteria such as: correlation coefficient, mean square error and standard deviation. Finally, it was determined that the two models fit easily to the values obtained in the field measurements; however, the difference presented by the Okumura-Hata model was smaller in comparison with the SUI model; but the latest one allowed a better fit to the propagation model than the Okumura-Hata model.

In general, the MIMO technology is used to transfer data from a protocol such as Wi-Fi in 5G networks. This is due to the increased bandwidth and capacity. The 802.11n protocol, which, using the technology described in it, allows you to reach speeds of up to 350 megabits/second. The quality of data transmission has improved even in areas where the reception signal is low. An external access point with a MIMO antenna is a well-known one. The WiMAX network can now transmit information at speeds of up to 40 megabits/second, using MIMO. It uses MIMO technology up to 8 × 8 . Thanks to this, a higher transfer rate is achieved—over 35 megabits/second. In addition, reliable and high quality connection of the best quality is guaranteed. In this paper, we continue to work and enhance technical configurations of MIMO in 5G networks. The proposed model will improve spectrum performance, improve network capability, and speed up data rates. In a saturation point, the proposed method achieves that the signal to noise interference ratio is just 42.4%, the receiver signal strength is 92.94%, the downstream traffic is 48.76%, the upstream traffic is 45.62%, the bandwidth utilization is 97.43%, the speed is 95.79%, the connectivity between the access point is 90.6%, and the network security is 96.42%.
