5G path loss characterization at 60GHz

5G path loss characterization using SIVERS Semiconductors EVK 6002 transceivers and USRP B200mini (60 GHz) for outdoor environments. Realized in the context of the course "Wireless Communications" at the Universidad Nacional de Colombia (UNAL) - Bogotá DC. Data are taken in the greenhouses of the university campus.

Develop by:

• Julian Andres Castro Pardo    (juacastropa@unal.edu.co)
• Diana Sofía López        (dialopez@unal.edu.co)
• Carlos Julian Furnieles Chipagra   (cfurniles@unal.edu.co)

The project is based on the following steps:

• Experimental setup
• Data acquisition
• Data analysis and visualization
• Pathloss model comparison and validation
