Abstract: A measurement campaign has been conducted at 2.35 GHz with a bandwidth of 50 MHz to obtain the statistics and evaluate the capacity of the backhaul link. Based on the measured channel impulse response, the channel gain, the eigenvalue statistics and the capacity are investigated. The distribution and corresponding parameters for describing the eigenvalue dispersion, the maximum and minimum eigenvalues are given. It is found that the backhaul link is relatively stable, which shows small variance of the channel gain. In spite of the fact that there are not many scatterers in the backhaul link, the channel rank can be enhanced by using dual-polarized antennas. Thus, the backhaul link can provide enough capacity.
