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.

Extended network coverage

Up to 10 km coverage. Under ideal conditions, up to 10 km range with 3 hops. Each hop can achieve from 150 m to 3 km radio coverage.

High scalability

Repeaters allow for a single gateway to manage hundreds of devices under single-net deployments.

Seamless communication

Between Edge Devices and Edge Gateway through the Repeater. Compatible with CMT Edge for full network, device and data management.

Carrier-class design

Wireless radio performance, purpose-built IP67 ruggedised enclosure and flexible modularity.

Frequently asked questions

What is the K20 Edge Repeater?

The K20 Edge Repeater is a device that can extend the radio coverage of a network. It receives data from Worldsensing's Edge Devices and it hops it forward to the nearest repeater until data reaches final gateway. This network setup allows to extend radio communications in intricate topologies up to 10 km using three hops.

What is the recommended number of Repeaters in my LoRa network?

You can add up to 7 Repeaters into your network. However, note that the downlink transmission latency can be increased in configurations with more than 5 hops.

Where can I use the Repeaters and the LoRa network?

Leverage the K20 Edge Repeater and LoRa Tree network to tackle coverage challenges in complex geographical topologies, such as underground environments, tunnels or inside dam galleries. This monitoring solution can achieve up to 10 km of communication range in three hops with minimum latency.

How can I pre-plan the architecture of my LoRa Tree network?

You can map your site and perform a coverage test using the Link Test Tool from the Worldsensing App.
