what is the AUX antenna connector for?

hi,
on a PCIE-SIM7600x module there are GNSS, MAIN and AUX connectors.
GNSS and MAIN i know what it is good for, but what is AUX?
auxiliary antenna. Used to assist LTE or 2G signal acquisition.
you mean as secondary LTE antenna?
i found a manual of all AT commands of the SIM7600 module and it looks like it has its own WiFi & BT built in.
i thought AUX is maybe an antenna connector for that Wifi & BT of the SIM7600 module, beside the WiFi & BT of the ESP32 module.
for example. Regardless of sim800L or other signals, it will have an AUX interface. And SIM800L does not have WIFI function.
that's strange.
why does SIMCOM list AT commands for WIFI and BT in their SIM7600 manual (SIM7500_SIM7600 Series_AT Command Manual_V3.00.pdf),
but the SIM7600 module itself does not have WIFI/BT functioallity (SIM7600 Series_SPEC_202111.pdf).
or does that SIM7600 module support WIFI/BT over its USB-OTG?
(i read the harware design guids (SIM7600_PCIEMIFI_Hardware_Design_V1.01(221103).pdf) - WIFI, can be archived with a specific module version but needs additional hardware)
for others like me who has those questions about the AUX connector...
