1
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.
3 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.
