Expand Monitoring Range with LoRa Tree Technology
The K20 Edge Repeater extends the reach of single-network deployments by relaying data across challenging environments. Using field-proven LoRa Tree topology, it enables reliable long-range communication, making it ideal for underground monitoring systems and complex infrastructure where direct gateway connectivity is limited.
-
The K20 Edge Repeater extends the network range of single-net deployments
-
Field-proven tree network technology which has been tested for both straight and curved tunnels in underground mines
-
Up to 10 km of radio coverage for underground monitoring systems
-
Compared to other network topologies, long-range LoRa Tree topology offers the longest radio range in underground environments
Extend Network Reach with Multi-Hop Communication
The K20 Edge Repeater is engineered to provide extended radio range by retransmitting data from its associated nodes to the main gateway. Data can travel along multiple repeaters in hops before arriving at the main gateway, thus gaining significant longer range.
