A Pilot deployment validates the scalability of the Silvanet System in the most realistic environment. It provides sufficient sensors (400) and gateways (6) to monitor a relatively large area - about 400 to 500 hectares. The Site Management app is used to plan Packets that include deployment locations of sensors and gateways. The Packets can be assigned to different users who do the actual deployments.
The following shows a Pilot deployment with the Border Gateway on the edge of the forest and 400 sensors connected via a Mesh Network and Mesh Gateways to the Border Gateway.
Number of devices
The Pilot Deployment typically includes the following devices with the required treenails and other accessories:
- 400 Silvanet sensors (installed using treenails or cropwire)
- 5 Silvanet Mesh Gateways
- 1 Silvanet Border Gateways (an additional Border Gateway can be added for redundancy)
Sensors are further apart, such as 100 meters between devices and it uses sufficient Mesh Gateways to cover the area.
Understand the terrain of the Site area:
As the Pilot uses Mesh Gateways, the deployment area can be hilly, rocky and beside roadways. However, we recommend line of sight between Mesh Gateways and Border Gateways.
Sensor spacing can be 80 to 100 m between the sensors. Additionally, the sensors can be temporarily attached to trees using cropwire rather than permanently using tree nails.
Number of Mesh Gateways:
A Pilot deployment uses from 4 to 8 Mesh Gateways for an area of 400 to 500 hectares, depending on the terrain and RF signal propagation conditions. Hilly areas need more Mesh Gateways. Less dense and relatively level forest floors need less Mesh Gateways where 4 should be sufficient.
Border Gateways requirements:
We recommend powering the Border Gateway using a reliable power supply and where it can have Ethernet Internet connectivity. It is also possible, but not recommended, to power the Border Gateway using only its solar panel.
Preparing a deployment plan:
Consider how the deployment teams must traverse the forest so they can efficiently use the time. With such a large deployment area, several teams of two workers may be required to deploy all the sensors. Ensure you prepare one site Packet per team, taking into account how the team must navigate through the forest. Ideally, create one Packet for one day's worth of work for a single team.
To deploy 400 sensors and Gateways, a team of 2 people can deploy 20 to 50 devices a day. However, this depends entirely on the difficulty of the terrain and state of the forest floor. In general, deployment is achieved quicker when more teams are available to deploy the devices.
