Modulation 

OFDM modulation, 64 FFT points; BPSK, QPSK, QAM16, QAM64

 The actual available frequency channels and bandwidth are defined by the selected Sub-Band, which reflects the 

applicable regulatory constraints. For more details refer to section 

4.2.2.4

). 

2

 The actual maximum available output power for each modulation level is defined by the selected Sub-Band, which 

reflects the applicable regulatory constraints. For some countries the power may also be limited by limitations on 
the maximum EIRP (also included in the Sub-Band parameters) and the Antenna Gain parameter. For more details 
refer to section 

4.2.2.4

 and to section 

4.2.6.2.8.1

. For information on specific HW and Country Code limitations, see 

the Country Codes document.

 The sensitivity values are for a bandwidth of 20 MHz. When using a 10 MHz bandwidth, the sensitivity for each 

modulation level is 3 dB lower. For a 5 MHz bandwidth (900 MHz band) the sensitivity for each modulation level is 6 
dB lower. 

4

 Modulation Level indicates the radio transmission rate and the modulation scheme. Modulation Level 1 is for the 

lowest radio rate and modulation scheme. 

5

 Modulation Level 8 is supported only in units with HW Revision B and above.
