The repeater retransmits 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 up to 150 m to 3 km radio coverage.

Highly scalable

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 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.

What can I do in advance to design my LoRa Tree network?

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

What they say about us

Discover how Worldsensing has made a positive impact, providing reliable solutions and exceptional support.

In the past, we would have done it with cables. It would have been a lot of work for the construction company. It’s not really competitive anymore to use cable systems in geotechnical projects. Read success story

Daniel Naterop
Project Manager, Huggenberger

It’s 100% satisfaction. Our client keeps coming back and asking for more digital nodes. The return on investment is easily less than a year for this. Read success story

Adam Dulmage
Businesss Development Executive, Mining sector, GEO-Instruments Canada (formerly GKM Consultants)

One of the Worldsensing gateways that we first installed has kept on monitoring for years, without any work done on it. I haven’t had to check that gateway since I installed it. This kind of reliability is one of the biggest advantages of this system. Read success story

Rodrigo Vicencio
Chief Operating Officer, Geosinergia

We are very pleased with the Worldsensing system. Data loggers are available for most types of sensors and mounting and configuration are easy and fast. One has full control over the gateways via the Worldsensing data server and data transfer also works great. In addition, Wordsensing offers very good technical support. Read success story

Øyvind Klevar
Board Member, Geonor

We've had a good relationship with Worldsensing for a number of years and we are one of their early adopters. We've really seen the value in a wireless solution. The Modbus protocol implementation on the gateway allows for seamless integration to existing communication infrastructure. This also isolates access to the data and reduces the impact of network outage in the area. Read success story

Ben Scott
Technical Manager, Geomotion

An important point in the project was the concrete anti-vandalism protection used to guarantee the safety of the equipment. Even with this protection, the system managed to transmit to the gateway more than 2 kilometers away. Read success story
