6.8Mb/s vs 850kb/s data rate

Hi guys,

For reliability, the lower the data rate, the more reliable it’s going to be right? Also longer preamble is better?

Alos what’s the performance difference between using 16Mhz PRF vs 64MHz PRF?

Hi @jzw01 ,

850 kbps requires a longer preamble, which provides better receiver sensitivity. However, it also increases the frame duration, so you need to dial back the effective Tx power level to comply with Tx power regulations. Therefore, we recommend sticking with 6.8 Mbps, the most commonly used configuration.

Kind regards,
Emre
