Duglas Ricardo Lopez Rojas

With over 30 years of experience in telecommunication business development, systems engineering, and network architecture, I bring a wealth of expertise as an electronic engineer. As a Cambium Networks certified instructor, I have a deep understanding of the design, planning, implementation, operation, and optimization of fixed access wireless broadband (FWAB) point to point and multipoint, microwave SDH, PDH, metro ethernet, enterprise and carrier-class WiFi. My proficiency extends to routing, switching (layer 2 and 3), IP network security, VoIP, RoIP, mobile indoor coverage systems (DAS and bidirectional amplifiers), trunking (TETRA, DMR), and SCADA communications. Additionally, I possess knowledge in cellular mobile networks (5G, LTE) and hold a Cisco CCNA certification. Alongside my technical skills, I am known for my strong leadership abilities, problem-solving aptitude, and collaborative approach. Fluent in English and holding a valid American visa, I am well-equipped to contribute to the success of any organization.
