Short range forest channel modeling in the 5 GHz band

This paper presents a wireless channel characterization for a short-range, temperate, medium density forest environment. This environment and frequency band have not been thoroughly characterized. We conducted measurements at a center frequency of 5.12 GHz with a 50MHz bandwidth signal and obtained impulse response estimates. Measured results for delay spread are presented; mean root-mean square delay spread values range from 64 to 87 ns, for link distances up to approximately 110 m. Maximum delay spreads were approximately 360 ns. The presented models should be useful for wireless system design and optimization in the 5 GHz band forest setting.
