7.2.4 Main antenna compensation
The total antenna gain (including eventual feeder cable loss) in dB for the
actual antenna used shall be configured at installation for correct maximum
output power capability.
The configured antenna gain must be the same or higher than the actual
antenna gain for the Gateway to operate within the limits for conducted and
radiated output power. The Gateway will transmit the maximum conducted
output power to respect the following limits in USA and Canada of conducted
output power maximum 27.5dBm and EIRP maximum 36dBm. The actual
maximum EIRP values of Gateway 5780 are therefore defined by the
maximum conducted output value + the compensation value (antenna gain +
feeder cable path loss,) which is input during installation.
Figure 19 Antenna compensation
Note that the antenna gain used must be within the maximum and minimum
gain of the antennas listed in Table 1 to be in compliance with regulatory
requirements.
7.3 Mobile network subscription (WWAN backhaul option)
WCDMA/LTE subscription (LTE recommended for performance)
SIM shall be unlocked (No PIN enabled)
7.4 Fault management
Under normal operation a control system monitors software and hardware of
the Gateway 5780.
The practical fault management is based around alarm and event notifications.
Reporting of some alarms is turned off by default, but can be reconfigured
when there is a need for a larger set of monitoring.
Furthermore, alarm filter persistency is set for some types of alarms by
default. This may prevent reporting of some types of alarms by default.
Alarm notifications can be enabled or disabled for the entire system. Disabling
alarm notifications means that no new alarm or event notifications are sent to
the management system.
