Gateways can be configured to perform pre-processing of the collected data from thousands of sensors locally before transmitting it to the next stage. Which of the following best reflects this statement?

The concept being tested is edge processing at the gateway. Gateways in IoT often act as boundary devices that sit between many sensors and the rest of the network. They can run lightweight data processing locally, performing tasks such as filtering out noise, aggregating or summarizing data, normalizing formats, compressing or deduplicating measurements, and even doing basic analytics or anomaly detection. By doing this pre-processing before data is sent upstream, the gateway reduces the amount of data that needs to travel over the network, lowers latency for local decisions, and helps cope with intermittent connectivity.

So the statement is correct: gateways can be configured to perform pre-processing of the collected data from thousands of sensors locally before transmitting it to the next stage.
