== Full-Duplex Radio

Full-duplex (FD) wireless is an emerging wireless technology allowing for simultaneous transmission and reception on the same frequency channel. To support research into FD, two FD transceivers have been integrated into the COSMOS Sandbox !#2.

Details about the Gen-2 FD hardware may be found [https://flexicon.ee.columbia.edu/content/gen-2-open-access-wideband-full-duplex-radios-cosmos here], and a tutorial on how to utilize the hardware and run experiments may be found [https://wiki.cosmos-lab.org/wiki/Tutorials/Wireless/FullDuplex here].
