If the same channel-width is allocated for a WiFi channel and also for a Sub-1 GHz channel, would the maximum allowable speed be the same for both channels theoretically?

If they differ, what is the theory behind the same?

If the channel width and SNR are the same, then the channel capacity in bits per second is the same.

    \$\begingroup\$ @alex.forenrich So does WiFi offer faster speeds because channel bandwidth of Wifi is usually higher than a Sub-1 channel? Thank You for your time \$\endgroup\$

    \$\begingroup\$ Pretty much. Generally, the higher the center frequency, the more bandwidth can be allocated. \$\endgroup\$
