Feasibility studies of LTE for the broadband service delivery in Professional Mobile Radio

Professional Mobile Radio (PMR) requires higher reliability with less dense infrastructure than usual public mobile networks. Potential implementation of the next generation public mobile radio system Long Term Evolution (LTE) in PMR can bring new features, e.g., real time video. However, its feasibility must be carefully investigated with realistic PMR applications. This paper presents such an investigation based on a ray tracing wave propagation model applied in the inner city of Hannover. Two typical PMR application scenarios - a patrol scenario in daily use and an emergent rescue - were defined and simulated. Different network setups and simulation parameters were compared to derive the optimal setting for the performance of the PMR system.
