Re: What is the real benefit of 802.15.4 compliant chip over others?

On the PHY level 802.15.4 use a DSSS modulation scheme which offers very good robustness. Only the 802.15.4 radios offer this modulation. Above the PHY layer a device like cc2520 adds significantly more advanced protocol offload capabilities than cc2500. While this is tailored to the 802.15.4 MAC layer...

Re: sensitivity as function of preamble and sync word
Sverre
The preamble, which ideally is a 0-1 sequence, is used to set up the correct gain in the AGC, sets up the data deciscion slicing level, and does bit synchronization. If the preamble is too short there is not sufficient time for the RX path to be set up correctly before the real data starts coming in...
