Channel bandwith ESP-NOW protocol

[alvaro_argente]

Hi,
I'm comparing the ESP-NOW protocol with Zigbee for a project, i have found that Zigbee have 16 channels with a bandwidth of 2 Mhz each channel in the band of 2.4 GHz.
Does anyone know the bandwidth of the channels of ESP-NOW protocol in the band of 2.4 Ghz?

It uses WiFi, so it generally is 13'ish overlapping channels at 20MHz in the 2.4GHz range.
