• An open competition

• To develop radio networks

• Which can thrive in the spectrum

without allocations

• Which learn how to adapt across

multiple degrees of freedom

• Which collaboratively optimize the

total spectrum capacity, moment-to-

Colosseum is a Channel Emulator

In a test environment, channel emulators replace the real-world radio

channel between a radio transmitter and a receiver by providing a faded

representation of a transmitted signal to the receiver inputs.
