Fixed wireless access channels in the 5GHz band have been measured with 8 element uniform linear antenna arrays at both ends, thus providing an 8x8 configuration. The measurements were performed at 3 different locations in downtown Toronto. The application of the time reversal (TR) technique in a multiple input-single output (MISO) can reduce the delay spread of the channel impulse response by a factor of 2-3, depending on the power allocation scheme.
