11.8 CW transmission
The BGAN XL Radio Module offers the capability to transmit a continuous wave (CW)
manually. This functionality is a special case of the unframed transmission
functionality (see section 11.9) and can be achieved in ‘service’ and ‘BPLT waveform
modes.
The CW is RRC filtered and generated with a symbol rate of 168000 S/s which generates
harmonics (+/- 168 kHz away from the CW). The typical level of this harmonic is -50dBc
