Using Modeling and Simulation to Assess Challenges and Solutions for 5G Fixed Wireless Access
One of the planned technologies that may change the digital landscape in the early rollouts of 5G is fixed wireless access (FWA), which will provide new and more flexible wireless solutions for broadband for the last mile to the home. In this paper, we use new modeling and simulation techniques to investigate some of the most critical challenges that FWA faces for operation in the physical environment at millimeter waves.
