Commercial in confidence
The private encryption keys are controlled by the LoRa network operator, who
controls the distribution of the keys to the intended installation personnel only.
From the factory, Gateway 5780 is not active and cannot operate until it is
configured by a qualified installer with the required security access. To enable
the Gateway 5780 and to put it into operational mode, including enabling
transmit power capability, the correct radio configuration including site
configuration details such as antennas and antennas gain information must be
actively set via the Operation and Maintenance configuration.
The Users of Gateway 5780 are the physical sensors that connect to it and as
such they will never have any access to be able to change any configuration
of Gateway 5780 so that it can operate outside of the radio parameters under
which the Gateway has been certified and approved for correct use.
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.
7.2.2
Backhaul settings
Some general examples of areas that must be configured are listed below. For
actual installation details refer to Gateway 5780 installation documentation.
Type of IP network including ports and network settings must be
configured at installation. E.g. firewall/zoned network must be configured
for the Gateway 5780 network settings.
The operation and maintenance communication settings for SNMP
handling to the Gateway 5780 must be configured.
NTP (Network Time Protocol) server must be reachable in the network.
The RTT (Round Trip Time)/latency shall be kept as low as possible to
avoid performance degradation.
7.2.3
GNSS antenna compensation
Compensation of the length (meters) of the cable, GNSS port to the GNSS
antenna port (e.g. GPS). This is used to compensate for the electrical time
delay from antenna into the receiver on the Gateway 5780.
