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.
