Portable relay nodes pass the signal along a chain (multi-hop), giving teams another way to stay in contact where a conventional repeater is hard to place.

01 Where LoRa can fit

Spread-out, changing work areas.

LoRa walkie talkies carry voice over a LoRa radio link. Obor Kuasa plans, sets up and supports LoRa walkie talkie systems for teams in Malaysia.

Illustration: plantation worker at dawn beside a relay tripod

Plantations

Spread-out outdoor sites where teams work far apart.

Illustration: quarry with haul trucks from above

Quarries and mining

Temporary or moving work areas, where relay nodes can be repositioned as the work moves.

Illustration: transmission line corridor

Utilities corridors

Long outdoor routes where a conventional repeater is hard to place.

Illustration: guard at a perimeter fence in rain

Campuses and facilities

As a second communication path alongside an existing radio system.

02 Follow the signal

One hop at a time, across the terrain.

01 / Problem
Teams work far apart
Spread-out or moving work areas where handhelds lose contact and a conventional repeater is hard to place.
02 / Relay
The signal is passed along
Portable relay nodes pass the signal along a chain (multi-hop) so the link reaches every work area.
03 / Moves
Nodes move with the work
Relay nodes can be repositioned as the work moves. Range depends on terrain, vegetation, buildings and node placement.

03 What we plan and deliver

Handsets, relay path, checks, support.

Range depends on terrain, vegetation, buildings and node placement, so we do not quote a fixed distance before checking the site.

Handsets

LoRa walkie talkies

Voice carried over a LoRa radio link.

Relay nodes

Multi-hop relay path

Portable relay nodes pass the signal along a chain so the link reaches every work area.

Illustration: relay node on a ridge above a quarry

Repositioning

Moves with the work

Relay nodes can be repositioned as the work moves.

Support

Handover and support

User briefing, a record of the setup, and support afterwards.

04 Coverage topology

A chain of relay nodes.

Select a block or a view. Light pulses travel from node to node; an existing radio system can stay in place as the main path.

05 How it works

Understand. Plan. Check. Support.

How we approach a LoRa deployment, in four steps.

01 / Survey
Understand the area and users
Where people work, how they move, and where contact is lost today.
02 / Design
Plan the relay path
Where portable relay nodes go so the link reaches every work area.
03 / Install & check
Check on site
Test calls along the planned path before handover.
04 / Support
Handover and support
User briefing, a record of the setup, and support afterwards.
