what is the range of NRF24l01+PA+LNA ?

what is the real life range of nrf24l01+PA+LNA (one with seperate antenna) ?
Its mentioned as 1.1km but some says you will get only 100m

What is the gain of the PA, LNA and the antenna, once you know these, you can use a simple calculator:

Don't expect anything near the 1.1 km range, that is probably the maximum range in lab conditions with LOS using optimally dimensioned directional antennas. If you achieve one tenth in your application then you can't complain.
