902-928 MHz BandExtend Sensor Connectivity for Continuous Monitoring
The K20 Edge Repeater strengthens wireless sensor networks by boosting signal reach and maintaining continuous communication between sensors and gateways. It retransmits data from associated nodes to a main gateway using a tree network topology, allowing data to travel across multiple repeaters (up to 8 hops) to extend coverage.
Ideal for challenging terrains, tunnels, mines and extended infrastructure projects — ensuring critical tilt, vibration and GNSS data is transmitted reliably even where direct gateway signals cannot reach.
Multi-hop data relay to extend range
Hundreds of devices per network
PoE-powered, no complex wiring
Weatherproof for harsh environments
Key Benefits
Expands coverage of sensor networks in hard-to-reach or remote locations where direct gateway signals cannot penetrate.
Maintains consistent communication even in challenging terrain or long distances with >99.7% transmission success rate.
IP67-rated housing built to withstand outdoor and industrial conditions including full dust ingress protection and water immersion.
Single cable carries both power and data. PoE injector included in the kit for simple installation.
What Makes the K20 Edge Repeater Different
Field-proven range extension technology designed for underground and challenging monitoring environments.
Multi-Hop Range Extension
Tree network topology supports up to 8 hops with 150m to 3km per hop — extending coverage into tunnels, mines and dense urban environments where direct signals cannot reach.
High Transmission Reliability
>99.7% transmission success rate in default network configuration (3.125 messages/min). High demand mode supports 8 messages/min with >98.7% success rate.
Seamless Network Integration
Operates as a transparent range extender within existing Worldsensing networks. Compatible with both Cloud and Edge gateway deployments without additional configuration.
IP67 Rugged Design
Weatherproof IP67-rated enclosure protects against dust, water immersion and extreme temperatures. Operating range from −40°C to +60°C for the harshest conditions.
Simple PoE Power
Power over Ethernet (PoE) supports both mode A and mode B — a single cable delivers power and data. USB-C also available for local access. Mean consumption just 4.5W.
Multi-Band Support
Available in standard (863-928MHz) and 915R (902-928MHz) variants to match regional regulatory requirements across EMEA, Americas, India and APAC.
Where the K20 Edge Repeater Deploys
Deploy the K20 Edge Repeater wherever wireless sensor networks need to reach deeper or farther.
Underground Mining
Extend network coverage deep into underground mine tunnels where direct gateway signals cannot penetrate. Maintain full sensor visibility for slope stability and seismic monitoring.
Metro & Rail Tunnels
Continuous sensor data from tunnel linings, track geometry and ventilation systems across long underground corridors with multi-hop repeater chains.
Large Bridge Networks
Bridge sensors located far from the gateway location can connect through repeaters — ensuring complete coverage across long-span and multi-structure sites.
Remote Terrain
Deploy sensor networks across valleys, hillsides and remote slopes where line-of-sight to the gateway is obstructed by terrain features.
Urban Canyons
Overcome signal blockage from dense buildings and infrastructure in urban monitoring environments where direct LoRaWAN range is limited.
Large Construction Sites
Temporary repeater deployment for construction monitoring networks covering expansive excavation and building sites with multiple sensor types.

It strengthens and extends wireless sensor networks, retransmitting data from associated nodes to a main gateway and enabling multi-hop communication — ensuring data from remote or hard-to-reach sensors reliably reaches gateways.
The repeater boosts weak signals, enables multi-hop communication across up to 8 hops, and reduces data loss across long distances or obstructed areas with >99.7% transmission success rate.
The maximum distance between hops ranges from 150 m to 3 km, depending on terrain and environmental conditions. With up to 8 hops, total network coverage can extend well beyond 10 km.
It is designed for underground mines, metro tunnels, large bridge networks, remote terrain, urban canyons and large construction sites — anywhere direct gateway connectivity is challenging.
It supports Power over Ethernet (PoE) both mode A and mode B (802.3af specifications), or 5V through USB-C. A PoE injector for indoor use is included in the kit. Mean power consumption is just 4.5W.
The K20 Edge Repeater works transparently within existing Worldsensing networks, compatible with both Cloud and Edge gateway deployments. No additional configuration is required — repeaters are automatically detected and managed by the network.
