Abstract:
1. A method of communicating between first and second radio heads of a line-of-sight point-to-point radio communications link, wherein the first radio head comprises: wherein the second radio head comprises: wherein the first and second radio heads are at first and second respective fixed radio head locations with a direct line of sight between the first and second radio head locations, wherein the radio communications link comprises a first data path from the first radio head to the second radio head and a second data path from the second radio head to the first radio head, wherein the method comprises: wherein the first and second signals are independent of one another and are transmitted in opposite directions of the communications link, wherein: the radio communications link comprises a third data path from the first radio head to the second radio head and a fourth data path from the second radio head to the first radio head, wherein the first radio head further comprises: and wherein the second radio head further comprises: wherein the method further comprises: wherein the first, second, third, and fourth signals are all in a same allocated frequency band, wherein the first, second, third, and fourth signals are at the same center frequency, and wherein a transmission radiation polarity for the first and second signals is the same and is orthogonal to a transmission radiation polarity for the third and fourth signals, wherein bandwidths of the third and fourth signals are at the same center frequency, a portion of the third signal is received by the sixth antenna, and a portion of the fourth signal is received by the eighth antenna, and wherein the method further comprises:
