Link-layer performance of 2×2 780MHz and 2×2 2.3GHz MIMO systems

Link layer capacities of 2.3GHz and 780MHz antennas in 2×2 MIMO systems are compared. Simulation results show comparable performance for these two systems. Although a much better performance was expected from the 2.3 GHz system compared to the 780MHz system, the orientation of the antenna pattern played a significant factor in link layer performance. In the simulated designs, the orientation of the antenna pattern favored the 780MHz antennas.
