Fit linear spaces
Chainage and section identifiers suit construction and inspection workflows.
LINEAR SPACE POSITIONING
Keep location continuous along the work route.
Manage people and assets in long, narrow spaces using one-dimensional chainage and section maps. Plan around bends, branches and obstructions instead of applying a straight-line range claim to the entire tunnel.

Dual-channel stations + directional antennas + compatible terminals
HOW IT WORKS
Dual-channel UWB stations and directional antennas observe corridor position, then map it to chainage and zones. The specification describes single-station 1D positioning; confirm ranging sequences and direction detection with compatible tags.
Record chainage, bends, branches and construction obstructions.
Install antennas, stations, PoE and backhaul.
Validate location, handovers and coverage boundaries.
Use chainage for personnel counts and zone-event applications.
Chainage and section identifiers suit construction and inspection workflows.
JJ-U provides an IP67 cast-aluminum station with antennas and brackets.
PoE carries data and power; mini program or AC tools manage configuration.
DEPLOYMENT ESSENTIALS
01JJ-U nominal ranging accuracy is 30cm and the 400m transmission figure assumes line of sight. Bends and vehicles may require additional coverage.
02Single-station 1D support is not unrestricted 2D/3D positioning. Branches need suitable maps and deployment planning.
03Match tag channels and protocols. Select equipment for hazardous areas using its actual certificates and project requirements.
