Pathloss 5.0 Workshop

Radio transmission tower against sky background

This 3-day course comprehensively covers all the aspects of design, optimization and planning of microwave transmission using Pathloss 5.0 planning tool.

Participants will learn about the design, operation, deployment, and application parameters of transmission networks, including 2G to 4G technologies. The course covers the visualization of microwave transmission effects through the Pathloss 5.0 planning tools and provides an overview of the planning concept of transmission networks, including the ITU-T recommendations.

Additionally, participants will learn how to mitigate interference issues, calculate the effects of multipath, reflection, and diffraction processes, and optimize the microwave network to meet latency and throughput constraints for different applications. The course concludes with a discussion of network designing in 3D mapping and its configuration.
