Can anyone say what the difference between the
XBP9B-XCST-001: XBee-PRO XSC S3B 9600bps
XBP9B-XCST-002: XBee-PRO XSC S3B 19.2 Kbps
Are? Other then the data rate? Does one get better range? If they are both exactly the same, why would anyone take the unit that transmits less data for the same price?
