Overview
The Inventory Master’s LoRaWAN field tester kit for helium network monitoring is a plug-and-play and all-in-one LongFi network monitor for Helium network. It will help you particularly know how many Hotspots around can be touched for a given position, enrich the network mappers to know each other and share the real network coverage.
Features
- Ready to go
- Compact size
- Directly display network
- Monitor the LongFi network
