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?


1 Answer 1


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\$ Feb 26, 2015 at 5:49
