Relationship between data rate and noise

About the data rate item of 5.4 Receiver Opetation in the data sheet of nRF24L01 +.
Sensitibity is -82 dBm at 2 Mbps and -94 dBm at 250 kbps, is 250 kbps more susceptible to noise from other communication at 2.4 GHz?
Will the sensitivity rise make it easier to pick up noise?
Is it better to raise the data rate if you want to improve noise resistance?
Thank you.

  • Hi,

    Typically all communication in the 2.4GHz are short packet communication, meaning that if you increase the transmission time, it is more likely that you will experience interference in an environment with much 2.4GHz traffic. So increasing the on-air time with 8x (2Mbps->250kbps) will increase the risk of collisions in the 2.4GHz band, which may cause more re-transmissions and increased delay in a noisy environment. 

    Best regards,
