Device Overview

The USRP Network Series offers high-bandwidth, high-dynamic range processing capability. The Gigabit Ethernet interface of the USRP Network Series allows high-speed streaming capability up to 50 MS/s in both directions (8-bit samples). These features, combined with plug-and-play MIMO capability make the USRP Network an ideal candidate for software defined radio systems with demanding performance requirements.
