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 101 E band of operation at 60 GHz. A common medium access control (MAC) block may be utilized between the dual radios. ## Claims ### Claim 1 A hybrid band radio with multiple antenna arrays for communicating outbound data to one or
