K20 Edge Repeater

Worldsensing K20 Edge Repeater extends the network range of single-net deployments by retransmitting data from connected nodes to the main gateway. Data can travel across multiple repeaters in hops before reaching the gateway, significantly increasing communication range. The field-proven tree network technology has been tested for both straight and curved tunnels in underground mines.
