• 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-
moment
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.
