RTLS & Smart Gate Management

Barcodes tell you what was scanned; RTLS tells you where everything is right now, including things nobody scanned. Together they close every gap.

Anchor beacons installed in the tracked area and tags on forklifts/pallets. MSF delivers the site survey, installation and calibration.

Paired scanner logic and label data determine source and destination, so the correct ERP movement type is posted automatically.

Enough that four anchors have line of sight to each tracked point. Three is the mathematical minimum, but it leaves no margin: one blocked path and the position drops out, and tracking a mast-lifted load in three dimensions needs the fourth. That makes the count a function of racking, ceiling height and bay layout rather than floor area, which is why it comes out of a site survey. Each anchor also needs power and a network drop, so budget the cabling as well as the hardware.

Centimeter accuracy - the 10 to 30 cm in the spec - is what you get with clear line of sight to the anchors. Steel racking, mesh cages and metal walls reflect and block the signal, so there the position degrades towards telling you the aisle or the zone rather than the spot. A survey done in an empty building will not show this. Survey with the racks full, and plan BLE or a gate scan where UWB cannot see.

In practice yes, because the tag is on the truck, the truck has one driver on a shift, and the gate scan records an operator with a timestamp. Decide what the data may be used for before installation: which roles can see an individual trace, how long traces are kept, and whether routine reporting is by zone instead of by person. Where a works council exists, agree that scope with them in writing.

Your maintenance people, and the interval depends on reporting rate: a forklift tag beaconing several times a second does not last like a pallet tag that wakes on movement. Forklift tags can run off truck power, but that means a DC converter and a fitting per truck, best done during the truck's service. Tags report battery level and go quiet when they die, so the dead ones are visible, but somebody must work that report and find the tag in the rack - at hundreds of tags, a standing job.

It is corrected the way any other wrong posting is, with a reversal in the ERP, so agree who is allowed to do that before go-live. The commoner failure is a scan that should never have happened: a forklift passing a door to turn around, or a pallet carried through on someone else's load. Those surface as flagged movements for someone to review, and that only works if a named person clears the list every day.

RTLS tells you where the tag is. It does not tell you what is on the pallet or whether the goods are any good. Rebuild a pallet, move stock by hand, or leave a tag on an empty carrier and the system keeps reporting the old identity with full confidence. Quantity, lot and quality still come from the scan and the booking. Position and time are what RTLS adds; it does not replace an inventory record.

Yes. RTLS answers where something is now and which gates it passed; a WMS decides where it should go, allocates by FIFO or lot rule and holds the stock record. RTLS on its own gives you an accurate live map of an unmanaged warehouse. The combination that pays is the WMS owning location and stock logic while RTLS supplies the movements automatically, with nobody keying them.
