The 400-node Open-Access Research Testbed for Next-Generation Wireless Networks (ORBIT) radio grid testbed at WINLAB, Rutgers University. The testbed provides 400 programmable radio nodes for at-scale and reproducible emulation of next-generation wireless network protocols and applications. The ORBIT radio grid can be accessed by experimenters via an Internet portal, which provides a variety of services to assist users with setting up a network topology, programming the radio nodes, executing the experimental code, and collecting measurements. The testbed also supports end-to-end wired and wireless experiments using a combination of ORBIT and OpenFlow switch/router nodes under the same experimental execution framework.

A programmable phased-array antenna in the WiMi millimeter-wave wireless testbed. WiMi (Wisconsin Millimeter-wave Software radio) is the first 60 GHz testbed with a reconfigurable radio frequency (RF) front-end and software-defined baseband processing modules. It is intended as an instrument to spur the research in 60 GHz ultra-high-speed communications and fine-grained millimeter-wave sensing applications.
