WIRELESS & SENSING
7.6.13. Digital Modulation Schemes
FCC Part 15.247 allows for systems employing digital modulation techniques to transmit up to 1 W, provided that
the 6 dB bandwidth of the signal is at least 500 kHz and that the power spectral density does not exceed 8dBm in
any 3 kHz bandwidth.
The SX1211 can actually meet these constraints whilst transmitting at the maximum output power of the device of
typ. 10dBm, thanks to the built-in whitening process described in section 5.5.6.2:
Figure 85: DTS 6dB Bandwidth
Figure 86: DTS Power Spectral Density
Conditions:
Pout = +10.6dBm
Fdev = +/-200kHz
BR=100 kbps (Chip rate=100kCps, as data whitening is enabled)
Packet mode, data whitening enabled
Note: Manchester encoding allows meeting an even lower power spectral density, at the expense of the bit rate
efficiency.
