Darío S.

Optimization of WOM's Network in 3G/4G/5G technologies, cell configuration, features, tuning, and others with the aim of improving network quality.

He does Radio Access Network Optimization Engineering with an expert vision at Entel in 2G, 3G, 4G and 5G technologies. On the frequencies 2G-3G 1900-900, 3G 1900-900, 4G FDD 2600,700,1900, 4G TDD 3500 and 5G NSA in 3500. It participates in the deployment of the 5G network (band 3500 with anchor 2600) in the initial cluster and then at the national level, allowing to provide the service of this new technology in Chile, year 2022.It implements Volte technology nationwide maintaining the quality of the Voice service and being the only network in Chile with national coverage of this technology. It implements 1900-band refarming from 2G and 3G to 4G technology, which produced a 17% throughput improvement in 4G technology. It performs access optimization tuning nationwide with the use of drive test and ActixOne tool to improve DL and UL throughput and interference in the indicated technologies, managing to keep Entel as the number 1 in quality of service in Chile.

Performs Engineering of Optimization of the Radio network of Entel in the technologies 2G, 3G, 4G . In its frequencies 2G-3G 1900 and 900, 4G FDD 2600,700 and 4G TDD 3500. Implements LTE capabilities such as Carrier Aggregation, Mobility Control Poor Coverage, Cell Subscription Capacity, MIMO, IoT, CATM. Implements TDD 3500 Technology with Massive MIMO for BAFI (Fixed Broadband) service.

Performs Optimization Engineering of the Radio network of Entel (Multinational Service Provider), in multiple technologies and architectures of Cellular Networks and Wireless Communications (RF Wireless) such as: 2G, 3G, 4G, WiFi, Satellite Links and others. Designs, redesigns, analyzes, diagnoses, implements and generates advanced level solutions to complex problems associated with the operation of the entire network (End to End service), at the level of specialist and expert consulting engineer. The technologies developed have been: In 2G network GSM1900,900 in 3G HSDPA+ 1900,900, 4G 2600 and 700. Performs Measurements, Analysis and Validation of the RF spectrum for strategic decision making. Designs and develops processes and methodology for the implementation of new technologies in the Entel network without reducing KPI service quality indexes, allowing it to be the n°1 in Quality in Chile.

Plans and models growth of Entel's Radio network based on the company's projected growth requirements. Generates network expansions and requirements for new cell sites. It generates the requirements for the purchase of equipment and investment for each Annual Plan (representing 70% of the company's investment). Designs and Implements Growth Modeling at the cell level, using own tools developed and created using the Erlang model and advanced trend calculation polynomials. It uses Planet coverage simulation software for Cell Planning of the Entel network. Implements and tests new functionalities associated with increasing installed capacity to improve the Grade of Service (GOS) of the network. Deploys new equipment to the network to improve performance of network nodes. Responsible for achieving and maintaining the GOS meeting the levels of international demand, in accordance with the objectives of the company. All this work was done at the birth stage of the company in Chile and during its first 5 years. At that time of GSM technology.

Performs Management and Implementation pioneer of the first GSM network (Global System for Mobile communications) in South America in 1997.He leads a multidisciplinary team of engineers and technicians for the construction and installation of cell sites that meet the committed Radio Frequency requirements. Determine location of new sites using charts and Rasputin simulation software. Performs Survey (Inspection, gathering of information) and validates in the field better position for locating cell sites. Evaluates and Reviews Cell Site Project Design documentation. Performs tests of new technology equipment. Responsible to the subtel authority for the official delivery of Entel's GSM network (TIM Italia).

Projects of measurements of quality of electricity supply in different clients (Petrox, Telefónica CTC Chile and others).
