LTE Ethernet switch

Hello, for one of my projects, I’m looking to create an Ethernet switch which has LTE enabled by a Quectel modem. Can you advise on the modem to use, and if there are any reference designs available?

Secondly, I understand Quectel only have the SGMII interface, so I will need am Ethernet switch IC with an SGMII interface, can you suggest any that are readily available?

Thanks.

EC20\EC25 and other modules all support the SGMII interface, and you are welcome to purchase them.
