Have a look at this thread for a range check that gave a distance of 435m.
As long as it's line-of-sight the radios perform really well.
As soon as the signal encounters brick walls and other solid objects - signal rapidly deteriorates.

Using nRF24L01 radios as part of a weather station

This is an extension of the weather station project one of my IoT students tackled last year (2019). The objective was to have a remote sensor (located in one of the school's gardens) to send temp/humidity/pressure readings to a database using MQTT. Initially a Wemos D1 Mini was used but the WiFi range of the ESP8266 limited the distance the sensor could be placed from the school. Someone suggested I should look at the inexpensive UHF radios - - nRF24L01 as an alternative. I've just spent a …
