Could we change MAC_SPEC_ED_MIN_DBM_ABOVE_RECEIVER_SENSITIVITY to Increase communication distance ?

Other Parts Discussed in Thread: CC2530

Hi  all

there  is a question  of  the MAC_SPEC_ED_MIN_DBM_ABOVE_RECEIVER_SENSITIVITY !

someone says  that  change  the vaule of MAC_SPEC_ED_MIN_DBM_ABOVE_RECEIVER_SENSITIVITY could increase communication distance~~

just like  that 

default :

/* Threshold above receiver sensitivity for minimum energy detect in dBm (see 6.9.7) */
#define MAC_SPEC_ED_MIN_DBM_ABOVE_RECEIVER_SENSITIVITY             10

/* minimum receiver sensitivity in dBm (see 6.5.3.3) */
#define MAC_SPEC_MIN_RECEIVER_SENSITIVITY -85

          new  :

/* Threshold above receiver sensitivity for minimum energy detect in dBm (see 6.9.7) */
#define MAC_SPEC_ED_MIN_DBM_ABOVE_RECEIVER_SENSITIVITY              1

/* minimum receiver sensitivity in dBm (see 6.5.3.3) */
#define MAC_SPEC_MIN_RECEIVER_SENSITIVITY -94

 

i saw  the receive sensitivity  vaule of  the CC2530  -97 dbm

so is  that mean above change is OK  ?

BR!

  • Yes, changing the vaule of MAC_SPEC_ED_MIN_DBM_ABOVE_RECEIVER_SENSITIVITY could increase communication distance. However, it might be unstable. This value is tested and provided by TI so it's not recommended to change it.
