The radio has two transmit channels and two receive channels, which can each be tuned independently. The X310 and UBX radio provide a tuning range between 10 MHz and 6 GHz, with up to 160 MHz of baseband bandwidth per channel. It is equivalent to a USRP X310, with two UBX-160 daughterboards and a GPSDO module, and an on-board Intel-based System-on-Module (SoM) computer. The USRP 2974 is a high-performance, stand-alone software defined radio (SDR) device. Future application notes will discuss the installation and configuration of the other layers of the stack, other network components such as the EPC and MME, as well as the integration of the handset side (the UE side) with connectivity to the public internet. Specifically, this document discusses the installation and configuration of the OAI eNodeB physical layer software.

This Application Note explains how to install and configure the OpenAirInterface (OAI) software on the USRP 2974 hardware to implement a 4G LTE cellular basestation (eNodeB).
