BreezeNET B 9 System Manual

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 .

In 5.4 GHz units with a detached antenna, if the gain of the antenna (as inserted into Antenna gain field) is

higher than 30 dBm, then the Maximum EIRP can vary by more than +/-3 dB. As regulations in most

countries limit the EIRP of units operating in the 5.4 GHz band, it is recommended to use detached anten-

nas up to and including 28 dBi.

The actual available maximum 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 40 MHz bandwidth ("Turbo mode"),

the Sensitivity for each modulation level is higher by 3 dB higher. For 10 MHz bandwidth the sensitivity

is lower by 3 dB.

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

for the lowest radio rate and modulation scheme.
