• Comprehensive skills in wireless network architecture (e.g. 5G-NR SA & NSA), network design and planning, including capacity planning.
• Familiarity with wireless link budget parameters and calculations (e.g. fade margin, receive sensitivity, interference margin, spectral efficiency).
• Experience with wireless network optimization and deployment including drive testing requirements and configuration, test tools setup (e.g., XCAL, NEMO, and TEMS), data collection and processing, and network parameter optimization.

Practical experience with wireless network design tools:

• Expertise in using radio planning tools, preferably Atoll, for coverage and interference studies.
• Knowledge in terrain and clutter data analysis as they impact wireless coverage.
• Expertise in applying and tuning propagation models using real-world drive test data.
• GIS and data analytics:
• Skilled in using GIS software, particularly QGIS, for mapping and spatial analysis.
• Strong abilities in analyzing wireless network data, including predicted coverage, drive test, and crowdsourced data.
• Proficient in data analytics and visualization tools such as Excel and Power BI, and capable of scripting in Python and SQL for data manipulation.

Soft skills:

• Excellent verbal and written communication skills, including effective presentation capabilities.
• Strong interpersonal skills, capable of working independently and collaboratively within a team environment.
