Locate every asset.
Manufacture every connected device.
LinkSense is a smart solutions provider running two businesses under one roof: RFID / BLE / UWB real-time location (RTLS) systems, and the IoT components that make those systems real — 18650 battery packs, Pogo Pin connectors, and PCB. From tag antenna to location engine, one team owns the full stack.
We don't just sell tags. We don't just build parts.
Most RTLS integrators buy their tags and boards from someone else. Most component shops don't understand the field conditions their parts end up in. LinkSense does both — location engine and system integration, plus in-house design and manufacture of the battery, connector, and PCB that determine whether a tag works in the real world.
We map the workflow first
We start with how assets, people, and tools actually move — then pick the right mix of RFID, BLE, and UWB, not the same answer for every project.
- Site survey and RF simulation
- Technology mix: RFID / BLE / UWB
- WMS / MES / ERP integration
We own the critical parts
Three components decide whether a tag works in the field: the 18650 battery pack defines runtime and safety, Pogo Pin defines charging reliability, and PCB defines RF performance and BOM cost.
- Battery pack design + BMS
- Custom Pogo Pin design & tooling
- PCB layout, prototyping & SMT
One team ships the whole thing
Hardware, firmware, location engine, and visualization software come from one team. One version, one interface contract, one throat to choke when something needs debugging.
- Tags / anchors / gateways
- Location engine & dashboards
- On-site commissioning & support
RTLS Solutions
RFID · BLE · UWB — combined by scenario, not sold as one-size-fits-allDifferent operations need very different accuracy, cost, and tag battery profiles. We treat RFID, BLE, and UWB as a toolbox: RFID handles gates and inventory, BLE handles room-level presence, UWB handles centimeter-grade trajectories and collision avoidance.
Gates & cycle counts
UHF RFID portals, handhelds, and shelf readers. Answers the three questions every warehouse asks: how many, where, did it leave?
- Portal read rate > 99%
- Battery-free passive tags
- Real-time WMS reconciliation
Room-level presence
BLE beacons with optional AoA. Lowest cost, fastest to deploy, years of battery life. Ideal for staff check-in, room-level assets, and mobile equipment tracking.
- Accuracy 1–3m · AoA sub-meter
- Tag battery 3–5 years
- Reuses existing BLE infrastructure
Centimeter trajectories
Ultra-wideband time-of-flight ranging. Strong against multipath and metal occlusion. Built for forklift anti-collision, tool traceability, and proximity safety.
- Accuracy 10–30cm, update 10–50Hz
- Geofence alerts & track playback
- BLE + UWB fusion on a single tag
| Technology | Accuracy | Range | Tag power | Per-point cost | Typical use cases |
|---|---|---|---|---|---|
| UHF RFID | Zone-level (gate) | 0.5–8m (reader) | Passive, no battery | Lowest | Warehouse cycle counts, gate in/out, tool check-out |
| BLE / AoA | 1–3m · AoA sub-meter | 10–50m | Coin cell, 3–5 yrs | Low | Staff check-in, mobile equipment, room-level assets |
| UWB | 10–30cm | 20–80m (env-dependent) | Rechargeable, wks–mo | Mid–High | Forklift anti-collision, line-side traceability, proximity safety |
| RFID + BLE + UWB fusion | Zone / meter / cm tiers | Full-site coverage | Mixed | Tailored | Campus-wide unified asset governance |
// Figures represent typical engineering ranges. Final specs depend on site survey and RF simulation.
IoT Components
18650 battery pack · Pogo Pin · PCB — design and manufacturing under one roofThese three components decide the three things every connected device is judged on: battery life, connection reliability, RF performance and BOM cost. They ship into our own tags and gateways, and they're also available as a standalone business — sold to other device makers, or co-developed under JDM / ODM agreements.
18650 Battery Pack
Cell matching, pack design, and assembly, paired with our own BMS. Form factor, harness, and connector can be tailored to the host device — focused on cycle life and cell-to-cell consistency.
- Cells: 18650 cylindrical Li-ion, 3.6/3.7V nominal, 2400–3500mAh
- Pack voltage: 1S–7S (3.7 / 7.4 / 11.1 / 22.2 / 25.9V)
- BMS: over-charge / over-discharge / over-current / short / thermal; SMBus / UART
- Process: auto capacity-sorting & matching, spot-welded nickel strip, injection or heat-shrink, crimped harnesses
- Safety & certs: UN38.3, IEC 62133, CE, RoHS
Pogo Pin Design & Manufacturing
From spring-pin mechanical design to mass production and plating. Three use cases covered: charging contacts, test fixtures, and modular board-to-board connections. Spring force, plating, and life are tuned to your cycle count.
- Form: turned / stamped spring pins, single / dual-pin, magnetic connector variants
- Spec: pin diameter φ0.6–6.0mm, working stroke 0.3–3.0mm, custom spring force
- Plating: Au / Ni / Pd-Ni, contact resistance < 30mΩ
- Endurance: 100k–1M cycles by grade
- Custom variants: waterproof, high-current, high-frequency
PCB Design & Manufacturing
Circuit design, prototyping, and assembly for tags, anchors, and gateways. RF trace routing, power integrity, and antenna keep-out are designed together with the host mechanical form factor.
- Layers: 2–12 multilayer, FR-4 / high-frequency laminates
- Process: controlled impedance, blind & buried vias, ENIG / Imm-Sn / OSP
- Assembly: SMT + DIP + FCT
- Prototyping: as fast as 48h turnaround; flexible mid-volume runs
- Bundle options: antenna design & RF tuning
Two product lines. One shared foundation.
RTLS solutions define what the components must survive in the field. Component manufacturing keeps the solutions free of supply-chain surprises. R&D, testing, supply chain, and customers — all shared. That's how we shorten lead times and hold cost down.
A forklift anti-collision use case demands reliable uplink through metal occlusion. That requirement directly shapes the battery discharge curve, the Pogo Pin spring force, and the PCB antenna keep-out.
In-house battery packs and Pogo Pin tooling mean tag prototyping no longer waits on external production slots. Typical sample turnaround drops from 4–6 weeks to under 2.
18650 packs, Pogo Pins, and PCB are available as a standalone supply to other device makers, with full JDM / ODM support — including private label.
When positioning drifts in the runtime or battery life falls short of spec, there is no finger-pointing between integrator and component vendor. One team finds the root cause.
Capabilities: from cell to finished device
In-house lines and test equipment cover pack assembly, precision connector manufacturing, SMT, and finished-device burn-in.
