Mesh network connectivity
Each forest is unique. Different topology, difficult terrain, mountains, valleys, any feature that blocks transmissions are some of the many challenges facing quality connectivity. However, the Mesh Network uses LoRaWAN (Long Range Wide Area Network) to overcome transmission obstacles within a forest. LoRaWAN is a technology built on top of LoRa, a patented type of frequency modulation ideal for low-power, wide area networks such as required by Dryad Silvanet.
Another set of challenges occur for the Silvanet Border Gateway. The Border Gateway must connect to the internet to communicate with the Silvanet Cloud Platform. This is best achieved with Ethernet using PoE (Power over Ethernet) for a power supply. However, the Silvanet System is designed to meet the challenges of the most difficult deployment zones by providing options for connectivity.
If using the built-in Ethernet adapter/PoE is not possible, the Silvanet Border Gateway integrates an LTE radio (using 4G/LTE-M with 2G/GPRS fallback) to provide wireless connectivity via mobile networks. Should the deployed location have neither wireless or wired connectivity, the Silvanet Border Gateway has built-in support for satellite uplink using the SWARM satellite network. In all cases, however, the device's solar panel provides a fall-back power source should a power source become unavailable.
In short, the Border Gateway provides built-in support for the following Internet connectivity options:
- Ethernet (wired - recommended): Ethernet connectivity which requires access to a router. It also supports Power over Ethernet (PoE).
- LTE/4G (wireless mobile): LTE-M which requires access to a 4G Network. LTE-M (Cat-M1) is suitable for IoT. Fallback provided 2G (GPRS).
- Satellite (backup): Satellite uplink using the SWARM satellite network. Messages sent by SWARM are for Alerts only.
