Nex-G Innovations

The objective of the Distributed Antenna System (DAS) Training & Certification program is to provide participants with in-depth knowledge and practical skills in designing, installing, optimizing, and maintaining DAS solutions for improved wireless coverage and capacity. The program focuses on the principles of RF engineering, signal propagation, and integration of DAS with cellular networks.

Through hands-on exercises and real-world case studies, participants will gain expertise in deploying efficient in-building wireless solutions, troubleshooting system issues, and ensuring optimal performance for diverse environments, including commercial, industrial, and public spaces.
