Should I encrypt my mesh network? public wifi settings

The network is serving a captive portal for public wifi.
All wifi AP are open (non encripted).

Would encrypting the mesh offer any advantage?
In unecrypted mesh i can still use a secret password right? "option key"

config wifi-iface 'mesh0'
        option device 'radio5pci'
        option ifname 'mesh0'
        option network 'nwi_mesh0'
        option mode 'mesh'
        option mesh_fwding '0'
        option mesh_id '<your advertised mesh "name" goes here>'
        option encryption '**none**'
        option key '**your secure pass phrase goes here'**

i was thinking if i encryption the mesh it will just add overhead to the mesh wifi. and would not offer any security advantage because the AP that will serve clients is open.


Wow...I didn't know that was even possible.

anyone? unencrypted mesh have lower overhead?

Can you provide a link to the Wiki or instructions you have regarding encrypting a RF mesh link?

read the guide

   option encryption 'psk2/aes' # or 'none'

Thanks for the link.

(FYI, there's more mesh technologies other than 802.11s, so your link provided clarity.)

If you want security on RF, why wouldn't you encrypt?

Seems like a personal choice?
