I have some questions on WiFi channelization in 802.11n and 802.11ac. Here is the snip of List of WiFi channels (source: WiKi):
I am working on the L1 layer for 802.11n and 802.11ac model where I am transmitting and receiving some WiFi packets
- Transmitting and Receiving WiFi Packets on 20MHz channels is pretty straight forward. If I want to use 40 MHz channel (Channel 38) , I need to do channel bonding, where channel 36 and Channel 40 are used.
Is the centre frequency going to be 5190 (channel 38) ? If that's the case, why we even bother to use the term primary and secondary channels?
- What about the reception side? Do I need to tune my Rx to Channel 38 with samplerate > 2·40 MHz, or do I need to use any of the primary and secondary channels?
