Glossary

Haltian IoT terminology and definitions

A

API

Application Programming Interface - A set of protocols and tools for building software applications. Haltian IoT provides GraphQL and MQTT APIs.

Asset

An object that serves a purpose for a use case. Assets are objects to which data sources (like sensors) are attached. An asset can be statically assigned to a single space or dynamically travel between spaces.

B

BEACON

An operating mode of the Haltian EH Locator that does not route tag messages to other Haltian EH Locators/Haltian IoT Gateways, but is used to increase tag positioning accuracy.

BUILDING

One site can include several buildings. In Haltian IoT’s space hierarchy, buildings are organizational units within a site.

C

CSV

Comma Separated Values - A file format storing tabular data in plain text, with columns separated by commas and rows on separate lines.

F

FLOOR

A building can have several floors. Floors are part of Haltian IoT’s hierarchical space model.

G

GraphQL

A query language for APIs that allows clients to request exactly the data they need. Haltian IoT’s Service API uses GraphQL.

H

Haltian EH Locator

Sends and receives periodic messages that tags listen to. With RSSI-based information, the solution determines locations for tags. The locator can operate in two modes: as a router, and as a beacon.

Haltian IoT Center

Haltian server/cloud software that consists of IoT device management, data routing, compression, security, APIs, diagnostics, monitoring, firmware updates, and other backend services.

Haltian IoT Gateway

LAN or 4G (2G/3G fallback) connected device that delivers data to and from the backend. The gateway has local wireless connectivity (Bluetooth chipset) connecting to Locators/tags using Wirepas mesh protocol.

Haltian IoT Studio

Web application for device management, space configuration, and visualization. Organization managers can configure users, API keys, and access permissions through Studio.

Haltian Nano Tag

A small, Bluetooth low-energy device using Wirepas protocol for tracking assets. The tag has up to 5 years of operation time in inventory management use cases.

I

IoT

Internet of Things - Network of physical devices embedded with sensors, software, and connectivity enabling data exchange.

L

Locator Grid

The recommended maximum distance between Haltian EH Locators that together cover a specific area for optimal positioning accuracy.

M

MQTT

Message Queuing Telemetry Transport - A lightweight messaging protocol for IoT. Haltian IoT’s Stream API uses MQTT for real-time data delivery.

Measurement

Sensor data/values sent by devices. Measurements are stored in a time-series database and can be queried via the Service API or streamed via the Stream API.

O

Organization

The top-level entity in Haltian IoT access control. Users and API keys are assigned to organizations, and permissions are scoped to organizations or spaces within them.

P

Parquet

A columnar storage file format optimized for analytics workloads. Haltian IoT’s Data API exports data in Parquet format for integration with data lakes and analytics platforms.

R

RBAC

Role Based Access Control - Security approach restricting system access based on user roles. Haltian IoT uses RBAC with roles: admin, manager, designer, installer, and viewer.

ROOM

The largest individual unit of a floor that is covered with inventory and positioning infrastructure.

ROUTER

An operating mode of the Haltian EH Locator that routes messages to and from the Haltian IoT Gateway.

S

Service API

Haltian IoT’s GraphQL API for querying and mutating assets, spaces, devices, and measurements. Used for interactive applications and configuration.

Shared Wall

A light wall that can separate different spaces but does not block the wireless signal, such as metallic layers or thick concrete walls.

SITE

The highest level in the space hierarchy, e.g., a campus. Sites contain buildings, which contain floors, which contain rooms.

Space

A location unit in the Haltian IoT hierarchy: site → building → floor → room → zone.

Stream API

Haltian IoT’s MQTT API for real-time telemetry data streaming. Used for continuous data delivery to external systems.

T

TUID

Thingsee Unique Identifier - A device identifier printed on the physical device QR code (e.g., TSPR04EZU31901021). Used to identify devices during installation and can be mapped to UUID via API.

U

UUID

Universally Unique Identifier - The Haltian IoT internal device identifier used in MQTT topics and API responses. Not printed on physical devices.

W

Wall Corner

A corner formed by real physical walls, used as reference points for locator placement.

Wirepas

A wireless connectivity technology used by Haltian IoT devices for mesh networking, enabling devices to communicate and route data efficiently.

Z

ZONE

A specific area inside a room. A zone is defined by the application and is not directly related to physical infrastructure.

Zone Corner

A corner that does not necessarily have physical walls and is defined by the application for positioning purposes.

Zone Edge

An edge between a monitored zone and other areas surrounding the zone.
