Definition

xAnchor

BLE AoA Antenna array device, should be connected to an xAnchor+ device.

xAnchor+

Hardware component which is an Anchor with Computing Board with Linux OS and hosting system software and Scenario-specific software. Up to 3 xAnchor devices can be connected to a single xAnchor+.

Application,
App

A software component of the rtlscloud that provides specific functionality.
Currently there are following Applications available:
* iot spaces
* rtls analysis
* tracking
* Users & Permissions

Asset

An Asset to be located, with one tag or more tags assigned to it.

Device

A physical device having a unique identity and belonging to exactly one tenant. All data sent from a device, as well as from the application to the device, is therefore treated as belonging to the corresponding tenant. A Device can be shared between different Spaces.
Typical devices are:
* xAnchor
* xAnchor+
* xEdge
* Gateway

xEdge

This is a virtual device, that can be hosted on a dedicated hardware, or run embedded within rtlscloud. The purpose of this device is:
* Provide connectivity between rtlscloud and xAnchors, when required
* Provide runtime for scenario-specific software modules, that play central role for several xAnchors+

Feature

A single function or a group of functions that a Device can provide and configure. A device can expose one or more features (for example positioning or presence detection).

Gateway

Localization

Determining whether an Asset is located inside a predefined Location. It uses the Asset’s Position as input.

Location

Measurement

A physically determined value used for positioning — for example the distance between an anchor and an asset, or a received signal strength (RSSI). Positioning derives a Position from a series of measurements.

Notification

Onboarding

The process of connecting a device within rtlscloud.
* An xEdge can be connected to rtlscloud directly.
* An xAnchor+ can be connected either to rtlscloud directly, or to an xEdge, that in its turn onborads an xAnchor+ in rtlscloud.

Organisation

List of Users, Groups and Tenants which are managed by a Company.

OrgAdmin

An administrator role within an Organisation that manages its users, groups and tenants.

Policy

A rule in the authorization model that grants or restricts a role’s access to specific resources. Managed in the Users & Permissions application.

Position

Define concrete place where an Asset can be. It can have coordinates from an Coordinate System or any other unique identifier like device id, marker id or address

Positioning

A process of identifying a position of an Asset within some specific coordinate system, for instance Cartesian (Dekartes) Coordinate System, based on series of Measurements. This process can utilize one ore more methods such as Trilateration, Triangulation, and so on.

RTLS

Realtime Location System

rtlscloud

rtls analysis Application

Scenario

A digital twin template for specific HW infrastructure and use cases

Space

A Space serves as a root for a single location tree.

iot spaces Application

Tag

A physical tag which can be assigned to an asset. A Tag belongs to and unique within a particular tenant. A Tag is shared between all Spaces of a Tenant, but it may have a default space.

Tenant

A tenant is a logical entity, in German called “Mandant”, which serves as the root for a set of devices, assets and spaces, that means an Asset or Space or Device are always belonging to a single Tenant and exist only once within a particular Tenant.
