Abstract
Enhancement of wireless Channel Order and rank (ECHO) systems and ECHO repeater devices for enhancement of a wireless propagation channel for point to point or point to multipoint radio configurations are disclosed. The enhancement may be used for MIMO communications channels. Aspects support a richer multipath environment to increase the rank of the channel propagation matrix and/or to increase the magnitude of the coefficients of the propagation matrix between two or more radios. Such enhancement is applicable to backhaul radios in terms of increased range or in the number of supportable information streams. The installation, provisioning, optimization, control, monitoring, and adaptation of such devices within a network of backhaul radios is also disclosed. Wireless links and control between IBR and ECHO devices, and between ECHO devices and other ECHO devices, are also disclosed.
