Abstract: A radar detector is used with a radio link, the radio link characterized by high duty factor operation of a radio transmitter. The radar detector is located a sufficient distance from the radio transmitter that the radar detector is not overwhelmed by the radio transmission signal in that channel and can detect sufficiently low level radar signals to ascertain potential radio interference at the radar from said radio transmitter. The results of the radar detection are communicated to the transmitter in a way that impacts the transmitter's use of the sensed channel. This communication can occur reactively when a radar detection is achieved (the absence of which indicates no radar has been detected) and/or can be a periodic or event-driven indication that the channel is available for operation (the information expiring if the result is not refreshed).

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.

Abstract: A intelligent backhaul radio is disclosed, which can operate by zero division duplexing for use in PTP or PMP topologies, providing for significant spectrum usage benefits among other benefits. Specific system architectures and structures to enable active cancellation of multiple transmit signals at multiple receivers within a MIMO radio are disclosed. Further disclosed aspects include the adaptive optimization of cancellation parameters or coefficients.

Abstract: An intelligent backhaul system is disclosed for deployment in the presence of existing radio systems. A backhaul system for co-channel deployment with existing licensed and unlicensed wireless networks, including conventional cellular backhaul radios, Common Carrier Fixed Point-to-Point Microwave Service, Private Operational Fixed Point-to-Point Microwave Service and other FCC 47 C.F.R. §101 licensed microwave networks is disclosed. Processing and network elements to manage and control the deployment and management of backhaul of radios that connect remote edge access networks to core networks in a geographic zone which co-exist with such existing systems or other sources of interference within a radio environment are also disclosed.

Abstract: A intelligent backhaul radio have an advanced antenna system for use in PTP or PMP topologies. The antenna system provides a significant diversity benefit. Antenna configurations are disclosed that provide for increased transmitter to receiver isolation, adaptive polarization and MIMO transmission equalization. Adaptive optimization of transmission parameters based upon side information provided in the form of metric feedback from a far end receiver utilizing the antenna system is also disclosed.

Abstract: A hybrid band intelligent backhaul radio (HB-IBR) is disclosed that is a combination of two radios operating in different bands. Embodiments include a dual radio configuration wherein a first radio operates in a non-line of sight (NLOS) radio link configuration and a second ancillary radio operates in a near line of sight or line of sight configuration (n)LOS. For example, the HB-IBR may have an Intelligent Backhaul Radio (IBR) operating in the non-line of sight mode of operation within the 5.8 GHz unlicensed band, and have an ancillary radio link operating in the FCC part 101E band of operation at 60 GHz. A common medium access control (MAC) block may be utilized between the dual radios.

Abstract: A intelligent backhaul radio is disclosed that is compact, light and low power for street level mounting, operates at 100 Mb/s or higher at ranges of 300 m or longer in obstructed LOS conditions with low latencies of 5 ms or less, can support PTP and PMP topologies, uses radio spectrum resources efficiently and does not require precise physical antenna alignment.

Abstract: A intelligent backhaul system is disclosed to manage and control multiple intelligent backhaul radios within a geographic zone. The intelligent backhaul system includes multiple intelligent backhaul radios (IBRs) that are able to function in both obstructed and unobstructed line of sight propagation conditions, one or more intelligent backhaul controllers (IBCs) connecting the IBRs with other network elements, and an intelligent backhaul management system (IBMS). The IBMS may include a private and/or public server and/or agents in one or more IBRs or IBCs.
