Your hardware can record many datapoints, and bundle them up together into one packet for transmission in one big bundle. If you are reading a float off a sensor, you can get nearly 1 data point per minute, transmitted hourly, with a very naive implementation.

Much more with compression specialized to your use case and clever packet design.

You can also aggregate some stuff on the sensor and the send the aggregations.
