Border gateway deployments

When planning Border Gateway deployments, consider how you plan to provide the device with a reliable power supply and continuous access to the Internet. This section provides recommendations and types of deployment scenarios to assist you.

Planning recommendations

When planning Silvanet Border Gateway deployments, the location of the device should be chosen carefully.

Take into account the following recommendations when planning the location of the Border gateway:

  • Location: 2-3km distance from Mesh Gateways

    Place the Border Gateway in a location no more than 2-3 km from Mesh Gateways. Also, due to its connectivity to the internet, it requires more energy and the location should be chosen carefully. Ideally, it should be placed in a location with access to a reliable power supply (mains power) but it can also be powered by its pre-connected solar panel in off-grid locations.

  • Backup power supply: solar panel

    The pre-connected solar panel acts as a backup to charge the device's internal energy storage. If a loss of power occurs, the solar cell will keep the system running, thus keeping the Silvanet Network functioning. If the Border Gateway is to be powered by the solar panel, select a location with direct sunlight (such as a hillside) and keep it free from branches that obscure direct sunlight. Ideally, it should be placed on a tree or pole away from other trees in the forest.

  • Internet connectivity: Ethernet

    Ideally, the Border Gateway should be connected to the Internet using a fixed-Internet connection (router) but it can also be connected to the Internet using its built-in wireless connectivity (4G/LTE with 2G/GPRS fallback).

  • Range: Hillside to maximize range and sunlight

    Ideally, the Border Gateway should be installed on a hill to maximize the range. If the Border Gateway is to be powered by solar, a sunny location with direct sunlight should be selected. The solar panel should not be covered by branches.

  • Satellite backup: SWARM antenna

    For satellite connectivity, the Border Gateway provides a SWARM antenna to connect the Silvanet Network to the Internet.

Deployment scenarios

Depending on the availability of electricity and Internet, the following sections describe the possible scenarios for Border Gateway deployments.

Setup with a PoE-ready router

In this setup, the Border Gateway is connected to an Internet router (e.g. a cable or ADSL router) with support for Power over Ethernet (PoE).

Setup with a PoE-Ready Router

Setup with a PoE-Ready Router
  • Internet connectivity: The Border Gateway is connected to the Internet router using an Ethernet cable.
  • Power supply: The Border Gateway uses the PoE and an Internet connection provided by the router. In this setup, a separate PoE Injector is not needed.
  • Backup: As a backup in case of power failure or loss of Internet connectivity, the Border Gateway uses its built-in 4G/LTE, 2G/GPRS mobile radio and the SWARM Satellite connectivity. In case of a power failure, backup power is provided by the solar panel.

Setup with a router but does not support PoE

In this setup, the Border Gateway is connected to an Internet router (for example, a cable or ADSL router) that supports PoE, where:

  • PoE Injector (also called a PoE Adapter) is plugged into a mains power supply
  • Internet Router is connected to the PoE Injector with an Ethernet cable using the LAN-port of the PoE Injector
  • PoE Injector is connected to the Border Gateway using a second Ethernet cable

Setup with a Router (No PoE)

Setup with a Router (No PoE)
  • Internet connectivity: The Internet router connected to the PoE Injector to provide Internet connectivity.
  • Power supply: The PoE Injector plugged in to the mains provides the power supply for the Border Gateway.
  • Backup: In case of power failure or loss of Internet connectivity, the Border Gateway uses its built-in 4G/LTE, 2G/GPRS mobile radio and the SWARM Satellite connectivity. In case of a power failure, backup power is provided by the solar panel.

Note

When using the built-in Ethernet connection, this setup is supported only in combination with PoE. The solar panel does not provide enough energy to support Ethernet connectivity of the border gateway.

Setup without router but with mains power

In this setup, the Border Gateway is deployed in a location without a fixed-line Internet connection (without a router) but does have mains power, where:

  • PoE Injector is plugged into the mains power supply
  • Border Gateway is connected to the LAN port of the PoE Injector with an Ethernet cable

Setup without router but with mains power

Setup without router but with mains power
  • Internet connectivity: Provided by the Border Gateway's built-in 4G/LTE 2G/GPRS radio.
  • Power supply: Powered by the PoE Injector plugged into a mains power supply.
  • Backup: In case of network outage (loss of 4G/LTE, 2G/GPRS connectivity), use the Border Gateway's built-in SWARM Satellite Internet connectivity. In case of a power failure, backup power is provided by the solar panel.

Setup without router and without mains power

Typically, Internet access and a mains power source is unavailable in a remote location such as deep in the forest. Consequently, the Border Gateway deployed in this type of location has neither fixed-line Internet connectivity or a reliable power supply.

Setup without router and without mains power

Setup without router and without mains power
  • Internet connectivity: Provided by the Border Gateway's built-in 4G/LTE 2G/GPRS radio.
  • 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.
  • Backup: In case of network outage (loss of 4G/LTE, 2G/GPRS connectivity), use the Border Gateway's built-in SWARM Satellite Internet connectivity. As the solar panel is used to provide energy.

Backup setup

Normally, as a fallback, the Border Gateway supports several methods to ensure uninterrupted Internet connectivity:

  • Loss of Internet access: For example, due to loss of power or network failure, the mobile data connection (4G/2G) is used.
  • Loss of electricity: The solar panel charges the internal batteries and allows the mobile-data connection to be used.

Backup setup

Backup setup

However, if a loss of both Internet connectivity and power supply occurs, the following methods ensure uninterrupted Internet connectivity:

  • Loss of Internet connectivity (Ethernet and mobile): The built in SWARM-satellite connection functions as an emergency backup. In this situation, only fire alarms are sent. As the system runs in power saving mode, no other sensor data is transmitted.
  • Loss of power supply: The solar panel provides a backup emergency power supply.

Important

Should the installation location of the Border Gateway have neither a mains power supply or access to a mobile network (4G/LTE 2G/GPRS), the Border Gateway can still transmit minimal messages to the Swarm 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.
