Silvanet Border Gateway FAQs

Border Gateways sends messages received from the Silvanet Mesh Network and forwards them to the Silvanet Cloud using one of three services to connect to the Internet - Ethernet (requires access to a router), LTE-M mobile networks (requires 4G network) or satellite communication (as a backup). It needs to be "always on" which means it needs a reliable power supply. It also supports FUOTA to allow sensor firmware to be updated remotely.

The Border Gateway is supplied with a PoE Injector that provides a voltage range of between 36V and 57V. The PoE must be IEEE 802.3af compliant.

A Border Gateway can be offline due to three reasons.

• Network connectivity issues
• Power saving
• Insufficient power supply

If the Border Gateway loses network connectivity, it queues all the sensor data it received from sensors and Mesh Gateway and sends the data to the cloud once the network connection has been established. The same process occurs While the Border Gateway is in power saving mode.

If the Border Gateway is down due to low power, the entire system will be offline. In these conditions, the Mesh Gateway will attempt to send the data to the Border Gateway but since there is no Border Gateway the data will be lost.

The Silvanet Border Gateway should be attached to a tree or a pole at least 3 meters above the forest floor. At this height, the device has less interference from human or animal interactions.

A Border Gateway should face southward only in the norther hemisphere. Find a location where the solar panel can obtain maximum sunlight. Ensure it is oriented towards the sun (at 12:00 noon) whether in the northern or souther hemisphere.
