  During my experience, I have achieved significant advancements and contributions in the field of mobile device management. I stand out for my ability to optimize costs and manage contracts in the terminal certification process. Additionally, I have conducted thorough analysis of information sources to improve the management of these devices.One of my main contributions has been leading and developing the implementation of technical certifications for the latest mobile communication technologies, including LTE, VoLTE, VoWiFi, NB-IoT/LTE-M, eSIM, and 5G. This has required a strategic approach and the ability to quickly adapt to technological advancements.Furthermore, I have excelled in process optimization. For example, through the restructuring of the mobile terminal testing plan, I have managed to reduce execution time by 20% and decrease costs by 15%. This has streamlined the certification processes and improved operational efficiency.In addition, I have developed a mobile terminal model on the network using Python and Amazon AWS. Thanks to this, we have been able to reduce the uncertainty of terminals on the network by approximately 30%, which has been crucial in improving service quality and reliability.Another notable achievement has been my involvement in market research and leadership in the procurement of laboratory equipment for new access technologies in mobile terminals. This has allowed for a 10% reduction in acquisition costs and has made the terminal certification laboratory the first in the country to have instrumentation for measuring 5G devices.In summary, my career has been characterized by cost optimization, leading technical certifications, improving processes, and contributing to the advancement of mobile technologies. My strategic approach and ability to adapt to changes have been key in achieving these results.

Show less In the Technological Evolution Submanagement of Networks within the Vice Presidency of Technology and Operations at ENTEL, an investigation was carried out under the supervision of Jorge Sandoval Arenas, a professor of the Master's program at the School of Electrical Engineering of the University of Chile. The main objective of this research was to develop a "LTE Access Network Capacity Model."The study focused on the analysis and evaluation of the capacity of the LTE (Long Term Evolution) access network. The research team examined various aspects related to network capacity, including existing infrastructure, data traffic demand, service quality, and technical limitations.Using advanced techniques and methodologies, a detailed modeling of the LTE access network was performed. This allowed for a better understanding of how the network handles data traffic and how it can be optimized to meet the growing demand for high-speed mobile services.This study represents an important advancement in the field of LTE access networks and contributes to the development and improvement of mobile networks in general. The application of this network capacity model can benefit ENTEL and other companies in the sector by enabling them to make informed and efficient decisions to meet user needs and stay at the forefront of mobile technology.
