nrf24l01 module location on pcb.

[Fabio Fernandes]

I am using NRF24L01 modules sold on ebay. I have 3 boards where these modules are soldiers and notice a big difference in range. More distant of other components, better range. What is the safe distance to other components of the pcb? Thanks

I don't know what kind of modules you have or where you got them from, but we have seen other customers struggling with similar looking modules that was supposedly based on nRF24L01+, but in reality was fake/counterfeit versions of nRF24L01+. I don't know if that's the reality for the modules you have, but if you see different performance in the same setup with just changing the modules and you see some modules independently of placement performing worse than other, it could indicate that these are not the real deal.
