USRP N310 network-connected software radio (SDR) for reliability and flexibility in large-scale and distributed wireless systems.


The USRP N310 is a network-connected software radio (SDR) that provides reliability and durability for use in large-scale and distributed wireless systems. The USRP N310 simplifies wireless network monitoring and management by providing a unique way to perform remote tasks such as software updates, restarts, factory resets, self-monitoring, host PC / ARM debugging, and system health monitoring.
The USRP N310 is one of the highest channel densities on the SDR market, offering four RX and four TX channels in half-width RU format. The RF front uses two AD9371 transceivers, the latest RFIC technology from Analog Devices. Each channel provides instantaneous bandwidth of up to 100 MHz and covers the extended frequency range from 10 MHz to 6 GHz.
The open source USRP Hardware Driver (UHD) API and FPGA RF Network-on-Chip (RFNoC) development environment reduce software development efforts and integrate with various standard tools such as GNU Radio. Users can quickly prototype and reliably deploy a variety of SDR applications, such as wireless test benches, remote controls, spectrum tracking, and more. Note that the USRP N310 is not designed for quick setup.

Baseband processor

The baseband processor uses the Xilinx Zynq-7100 SoC to provide a high-user programmable FPGA for low-latency real-time processing and a dual-core ARM processor for stand-alone operation. Users can deploy applications directly to the pre-installed built-in Linux operating system, or transfer samples to a computer using high-speed interfaces such as 1 Gigabit Ethernet, 10 Gigabit Ethernet, and Aurora through two SFP + ports.


The USRP N310 has a flexible time architecture that supports traditional SDR timing techniques such as time base, PPS time base, and GPSDO, which enable MIMO systems with a large number of channels. In addition, the USRP N310 uniquely supports Ethernet-based synchronization using the open source White Rabbit synchronization protocol. White Rabbit ensures accurate baseband synchronization over long distances in the absence of GPS.
