Silvanet Mesh Gateway (Gen 2)

Using LoRaWAN, Silvanet Mesh Gateways act as range extenders to allow for widespread deployment of Wildfire Sensors in a linear or irregular areas.

Each forest is unique with varied topology and changing terrain such as hills, slopes, rock outcroppings, even mountains, valleys and cliffs. Linear areas such as railroad tracks, power lines, hiking trails can also have the same varied topology. So, each forest can have features that can interfere with reliable transmissions between devices. These challenges are overcome by using Dryad's Silvanet Mesh Gateways.

The Silvanet Mesh Gateway acts as a range extender by using the same Mesh Network used by the sensors to receive and forward messages to other Mesh Gateways and/or Border Gateways.

By forwarding messages, large-scale deployments of Silvanet sensors can be implemented throughout extensive forested areas or along remote stretches of rail lines, power lines and hiking trails.

As the Silvanet Mesh Gateway is proprietary to Dryad, the device is not open to 3rd party applications.

Key features

• Connects to the Silvanet Mesh Network (including Border Gateways) using LoRaWAN.

• Range between Gateways (Mesh and Border) is typically between 2 km to 6 km depending on topology and physical placement of the Mesh Gateways.

• Low power consumption that allow it to operate using only its solar panel for its daily energy requirements. The power consumption is calculated to be 3997Ws.

• Firmware is remotely updated using FUOTA (Firmware Update Over-the-Air).

• Each Mesh Gateway supports up to 100 sensors.

• Automatically registers with the Silvanet Cloud during the deployment process using the Device ID (scanned using a QR code).

Delivered components

Each shipment of a Mesh Gateway includes the following components:

• Silvanet Mesh Gateway

• Treenails (for permanent deployment)

• U-bolt Clamps, M10 nuts and washers

• 5 meter roll of garden wire (for temporary deployment)

• LoRa antenna (North America: 915 MHz, EU: 868 MHz, Asia: 433 MHz)

Dimensions

The dimensions of the Silvanet Mesh Gateway are (LxWxH) 68 cm (87 cm with antenna) x 29 cm x 5 cm and weighs 2.8 kg.

Border Gateway dimensions

Large scale deployments

Messages from Wildfire Sensors hop from Mesh Gateway to Mesh Gateway until they reach the Silvanet Border Gateway. This allows for a Silvanet Mesh Network to be extended to a very large-scale deployment consisting of hundreds or even thousands of sensors.

The patent-pending architecture uses a multi-hop mesh network of Mesh Gateways each serving as a standard LoRaWAN gateway to Silvanet Wildfire Sensors.
