NI USRPs

AERPAW will support various different types of USRP platforms from NI. For AERPAW fixed nodes, we have deployed USRP N310, USRP X310, and USRP B205mini for experimentation, and USRP B210s for spectrum compliance monitoring. Our portable nodes include a USRB B205mini for experimentation, and another USRP B205mini for spectrum compliance monitoring.   

• USRP N310 supports the frequency range 10 MHz to 6 GHz, with an instantaneous bandwidth up to 100 MHz per channel, as well as 4 RX and 4TX channels, 16 bit ADC, 14 bit DAC, and a Xilinx Zynq-7100 SoC. 

• USRP X310 supports the frequency range 10 MHz to 6 GHz, up to 160 MHz bandwidth, 2 RX and 2TX channels, 14 bit ADC, 16 bit DAC, and a Xilinx Zynq-7100 SoC. 

• USRP B210 supports frequency range between 70 MHz to 6 GHz, up to 56 MHz of instantaneous bandwidth, and 30.72 MHz of instantaneous bandwidth in 2×2 MIMO (61.44 MHz sampling rate). It has 2 RX/TX for MIMO, 12 bit ADC, 12 bit DAC, and a Xilinx Spartan6 SoC. 

• USRP B205mini, the smallest of the USRP we are deploying at AERPAW, features a Xilinx Spartan 6 XC6SLX150 FPGA and Analog Devices AD9361 RFIC direct-conversion transceiver. It supports frequencies between 70 MHz – 6 GHz with up to 56 MHz of instantaneous bandwidth (61.44 MS/s quadrature), and full-duplex operation. 

As part of Phase-1 General Availability, we expect to support only the USRP B205mini at the fixed nodes and the portable nodes. We provide various Example Experiments (ExEp's) with USRPs under the Experiment Repository section, that are developed and tested by the AERPAW team, using open source software srsLTE, OAI, and GNU Radio.
