Responsibilities

With regulators globally exploring spectrum sharing between cellular (5G/6G) and Wi-Fi networks (802.11ax, be, and bn), coexistence research has become a critical field requiring sophisticated modeling and analysis. In this role, you will participate in the development of a high-fidelity, link-level simulation framework using NS-3

The intern will assist the team to design and generate simulations and use results to provide recommendations on coexistence strategies and solutions

The intern will also assist in support activities that include: Develop and extend a link-level simulation framework to analyze cellular and Wi-Fi coexistence in shared spectrum bands

Implement PHY-layer models for cellular (e.g., LTE/5G/6G) and Wi-Fi (e.g., 802.11ax/be/bn), including modulation, coding, and waveform characteristics

Incorporate realistic channel models, including path loss, shadowing, fading, and interference coupling between cellular and Wi-Fi links

Compare the NS-3 link-level simulation with an in-house designed system-level Monte Carlo simulation to evaluate statistical performance under randomized network topologies and traffic conditions

Validate simulation results against standards specifications (3GPP, IEEE 802.11) and available measurement or reference data

Visualize and interpret simulation results using plots and summary statistics

Document simulation assumptions, methodologies, and findings in technical reports, papers, or presentations

Collaborate with senior engineers/researchers to refine models and explore new coexistence techniques
