8x8 MIMO RRH, 70 MHz to 6 GHz Software Defined Radio Reconfigurable Device—The MegaBEE 8x8 RRH is a software defined radio prototyping device for multiple input, multiple output (MIMO) systems. With the MegaBEE 8x8 RRH’s clocking structure, you can disperse antenna modules over a three-mile radius while maintaining phase coherence for distributed MIMO and for MIMO with greater coverage and capacity. It also features a portable form factor for field testing and is optimized for 5G cellular RF bands with an RF range from 70 MHz to 6 GHz. This device is programmable using BEEcube Platform Studio and has two Xilinx Zynq FPGAs to provide real-time signal processing and stand-alone operation. The MegaBEE 8x8 RRH works with the appropriate uplink/downlink FDD frequency bands as defined by the 3GPP specification.
