LoRaWAN limitations and MQTT Integration on Industry 4.0

Hi community! I hope someone could help me with this question :).

I was reading this great article: LoRaWAN and MQTT Integration for IoT Application Design.

I have a question regarding this statement:

in LoraWan, you cannot transmit information more often than every few minutes at the most

and then it states:

It is for this reason that in this article, I present to you an architectural approach that allows IoT developers and Solution Architects to enhance the capabilities of LoRa enabled IoT applications using MQTT

How the solutions proposed avoid this limitation? For example If I have a sensor communicated via Lora is the sensor capable to send updates every 5 seconds and then on the Lora Gateway layer we convert it to MQTT?

Thanks in advance.
