In this setup, the Border Gateway uses a mains power supply (via PoE Injector) and a router (via Ethernet). The solar panel acts as a backup power supply.
When using the built-in Ethernet connection, this setup is supported only in combination with the PoE Injector. The solar panel does not provide enough energy to support Ethernet connectivity of the border gateway.
Internet connectivity: The Border Gateway is connected to a cable or ADSL router via Ethernet which is connected to the PoE injector. In case of loss of Internet connectivity via the router, the Border Gateway uses its built-in 4G/LTE-M (or 2G/GPRS) mobile radio or its satellite connectivity.
Power supply: The Border Gateway uses the PoE Injector connected to a mains power supply.
Backup power supply: In case of power failure, the solar panel is used.
In this setup, the Border Gateway is deployed in a location without a fixed-line Internet connection (without a router) but has a mains power supplied by the PoE Injector.
Internet connectivity: Provided by the Border Gateway's built-in 4G/LTE 2G/GPRS radio. In case of loss of Internet connectivity via 4G/LTE-M (or 2G/GPRS) mobile radio, the Border Gateway uses satellite connectivity.
Power supply: The Border Gateway uses the PoE Injector connected to a mains power supply.
Backup power supply: In case of power failure, the solar panel is used.
Often Internet connectivity and a mains power source is unreliable in remote locations. Border Gateways deployed in these locations have neither fixed-line Internet connectivity nor a reliable power supply. In these cases, the Border Gateway uses its solar panel for a power supply. It uses mobile radio connectivity (if available) or a satellite uplink (to send fire alert signals to the Silvanet Cloud).
Internet connectivity: Provided by the Border Gateway's built-in LTE-M 2G/GPRS mobile radio, if a mobile tower is accessible. If a mobile tower is inaccessible, the Border Gateway uses a satellite uplink.
Power supply: Powered by the solar panel which charges the Border Gateway's internal energy storage. However, depending on the amount of sunlight, data transfer might be limited.
Normally, as a fallback, the Border Gateway supports several methods to ensure uninterrupted Internet connectivity. If the Border Gateway does not have wired or wireless Internet connectivity and/or power supply, the solar panel and satellite ensures uninterrupted Internet connectivity.
Satellite replaces wired or wireless Internet connectivity: If the Border Gateway loses Ethernet due to network failure and cannot connect to a mobile network, a satellite uplink provides as backup connection. However, only Fire alarms are sent.
Solar panel replaces mains power supply: The solar panel provides a backup emergency power supply. The solar panel charges the internal batteries and allows the mobile data connection to be used. As the system runs in power saving mode, no other sensor data other than fire alerts can be transmitted.
Natural disasters and connectivity
Should the installation location of the Border Gateway have neither a mains power supply nor access to a mobile network (4G/LTE 2G/GPRS), the Border Gateway can still transmit minimal messages to the satellite.
However, messages are restricted to fire alerts only. This scenario is applicable, for example, where natural disasters like thunderstorms or earthquakes bring down Internet connectivity.
