What happens on network disconnect

LPWAN Industrial Gateways / Concentrators RAK7249

Hi

In case both the Ethernet and lte fails, will the packets be buffered to be sent later ?

Similarly is there any buffering if the lte is slow ?

Now, there is no buffering when the network disconnect.
The packet must be sent out ASAP when the gateway receive it, otherwise this packet will lost.

Any ideas how we can minimise this problem ?
