Specifications
Every figure with its condition.
The technical page of Loki. How a cell works, what each product is made of, and what the law expects from the employer. What is not measured is not here.
Four or more anchors on the walls make a cell. The tag transmits a short signal; the anchors receive it and the engine on your server computes the position. Observed accuracy about 10 cm in a 25 m² cell with four anchors, line of sight. Larger cells are being characterised.
From the tag to your systems. The engine and Loki Manager run on your server, in Docker, also on an isolated network; positions reach your systems through the API.
| Parameter | Value | Condition |
|---|---|---|
| Accuracy indoors | ≈ 10 cm | Measured: 25 m² cell, four anchors, line of sight. Larger cells being characterised. |
| Position updates | 5 per second | Tag in motion; one every 2 s at rest. |
| Anchors per cell | 4 or more | Add anchors to cover more area; cells join by radio. |
| Cables between anchors | 0 | Each anchor needs a power supply and a network port, or the optional gateway in range. |
| Anchor power | USB-C, 5 V, about 1 W | Standard power supply. |
| Anchor network | Ethernet 10/100 | One switch port per anchor. Optional Bluetooth gateway, up to 7 anchors, for low-rate configurations only. |
| Calibration | Automatic | From the anchors themselves; no manual measurement. |
| Radio | UWB, IEEE 802.15.4z, 6.5 GHz band · Bluetooth LE | Certified radio module. |
| Tag battery | CR2450, replaceable | Autonomy being measured; published with its usage profile. |
| Server | Your server, Linux with Docker | Ubuntu Server supported; isolated networks supported; installation without internet access; no cloud, no licence fee. |
| Data | Stays on your server | Positions and history never leave the plant. |
| Integrations | REST API, WebSocket, webhooks | |
| Firmware updates | Over the air | Anchors from Loki Manager; tags over Bluetooth, on site. |
| Certifications | CE declaration for the boards: not issued yet | Radio module certified. ATEX: not certified; not for use in classified areas. |
| Warranty | 2 years | Against manufacturing defects. |
| Parameter | Value |
|---|---|
| Radio | UWB, IEEE 802.15.4z, 6.5 GHz band, for positioning · Bluetooth LE for setup and updates. Certified radio module |
| Update rate | 5 positions per second in motion, 1 every 2 seconds at rest; the tag senses its own movement |
| Battery | CR2450 coin cell, replaceable in a minute. Autonomy being measured, published with its usage profile |
| Mount | Clip, lanyard or adhesive; enclosure being finalised |
| Use | Indoors, within a Loki X cell |
| Firmware updates | Over Bluetooth, on site |
| Parameter | Value |
|---|---|
| Cell | 4 or more anchors on walls or ceilings; add anchors to cover more area; cells join by radio |
| Accuracy | About 10 cm, observed in a 25 m² cell with four anchors in line of sight; larger cells being characterised |
| Anchor power | USB-C, 5 V, about 1 W, from a standard power supply |
| Anchor network | Ethernet 10/100, one switch port per anchor. Optional Bluetooth gateway for low-rate configurations |
| Gateway | Optional: connects up to 7 anchors over Bluetooth instead of Ethernet; PoE or Wi-Fi; for low-rate configurations only |
| Cables between anchors | None: anchors synchronise over the air |
| Calibration | Automatic, from the anchors themselves; no manual measurement |
| Server | Your server, Linux with Docker (Ubuntu Server supported); on premise, isolated networks supported, installation without internet access |
| Software | Loki Manager and the engine included, no licence fee; the apps available today |
| Integrations | REST API, WebSocket, webhooks |
| Firmware updates | Anchors: over the air from Loki Manager |
Under D.Lgs. 81/2008 the obligations sit with the employer. Loki supports the risk assessment with data, feeds the emergency plan with a time-stamped log, and gives the safety manager who and where at the moment it matters. It does not make a plant compliant and it does not guarantee safety.
| D.Lgs. 81/2008 | Lone-worker and emergency measures: who is where, with a time-stamped log for the risk assessment and the emergency plan. |
| ISO 45001 | Emergency preparedness and response: positions and events available to the emergency plan and to your systems. |
| ATEX | Not certified: Loki is not for use in classified areas. |
| INAIL ISI | Safety investments of this kind are eligible for the INAIL ISI grant; we provide the documentation. |
| App | What it does | Status |
|---|---|---|
| Live map | Every tag on your plan, now. | Available |
| History | Where everything was. | Available |
| Integration | Positions in your systems. | Available |
| Fleet health | Know when something stops. | Available |
| Man down | A fall, or no movement: an alarm with the position. | In development |
| SOS | Press and hold. The control room sees who and where. | In development |
| Evacuation | Who is at the assembly point, who is not. | In development |
| Restricted areas | A zone you draw, a rule that holds. | In development |

| Intrusion monitoring | Movement where there should be none. | In development |
Apps run in Loki Manager on your server; the hardware stays the same. The list and the statuses are on the apps page.

A site survey takes a morning. We come with four anchors and a laptop, map a cell, and leave you the data.
