The chipping rate of Digi spread spectrum modulesChipping rates are related to the amount of bandwidth taken up by Direct Sequence Spread Spectrum radios. Most Digi radios use Frequency-Hopping Spread Spectrum to communicate. Frequency channels ranging between 25 and 50 independent frequencies between 902 and 928 MHz. We also provide a 25 channel 2.4GHz unit.
The XBee/XBee-PRO radios utilize DSSS technology. The XBee/XBee-PRO uses 8 chips/bit, and utilizes a bandwidth of 250kbps, for a total of 2 Mega-chips/s.
The XPress Ethernet Bridge also utilizes DSSS technology and currently chips at 1.536Mega-chips/s.
