Perseverance size

The 8 400-8 450 MHz (space-to-Earth) band is very congested, since it is being extensively used by all deep-space missions. The 34.2-34.7 GHz (Earth-to-space) and 31.8-32.3 GHz (space-to-Earth) allocations are not yet crowded, but deep-space missions have started using these bands.

Radio frequency communications for spacecraft are conducted between 30 MHz and 60 GHz . The lower frequency bands are typically more mature for SmallSat usage, however extensive use of these bands has led to crowding and challenges acquiring licensing.

The rover communicates with the orbiters and the DSN through radio waves . They communicate with each other through X-band, which are radio waves at a much higher frequency than radio waves used for FM stations.

Most often, Curiosity sends radio waves through its ultra-high frequency (UHF) antenna (about 400 Megahertz) to communicate with Earth through NASA’s Mars Odyssey and Mars Reconnaissance Orbiters. … That allows them to send more data back to Earth at faster rates.
