What is the relation between frequency and data rate?

Hi y'all.

I've seen different network cable(Cat6) that have different frequency and can support different data rate. Some brands have Cat6 cables that have frequencies of 250 MHz or 650 MHz and can support data speed of 1Gbps. But I saw another brand that have the same frequency but their cable ca support more Gbps. So my question: Is there a relation between frequency(MHz) and data rate(Gbps)? Does they affect each other?

​

Here is the brand I'm talking about. It's Ubiquiti UniFi Cat6 cable : https://www.gowifi.co.nz/specs/Ubiquiti_Unifi_CAT6_DS.pdf
