It is based on recommendation ITU-R P.2040 [1]. This work is part of the research project EConoM, funded by the Federal Ministry for Digital and Transport of Germany within the initiative InnoNT (funding number 19Ol22009F). It was supported within the TARGET-X framework, a project funded by the Smart Networks and Services Joint Undertaking (SNS JU) under Horizon Europe (funding number 101096614).

Systems of units may distinguish between base and derived units. Base units are the units which measure the base quantities for the corresponding system of quantities. The base units are used to define units for all other quantities as products of powers of the base units. Such units are called derived units for the system. http://qudt.org/schema/qudt/ hasUnit http://w3id.org/cno# hasAttenuationRate http://w3id.org/cno# hasDirection http://w3id.org/cno# hasFrequency http://w3id.org/cno# hasGain Simple description of the obstacle Material. http://w3id.org/cno# hasMaterial http://w3id.org/cno# hasPosition http://w3id.org/cno# hasPower Connects an element that the process has transformed. hasOutputElement Numeric value of for somethinig described by an unit. http://qudt.org/schema/qudt/ numericValue Conductivity Frequency Coefficient according to Table 3 of ITU-R P.2040-3 http://w3id.org/cno# hasConductivityFrequencyCoefficient Conductivity Frequency Exponent according to Table 3 of ITU-R P.2040-3 http://w3id.org/cno# hasConductivityFrequencyExponent Relative Permittivity Frequency Coefficient according to Table 3 of ITU-R P.2040-3 http://w3id.org/cno# hasRelativePermittivityFrequencyCoefficient Relative Permittivity Frequency Exponent according to Table 3 of ITU-R P.2040-3 http://w3id.org/cno# hasRelativePermittivityFrequencyExponent The WKT serialization of a Geometry. http://www.opengis.net/ont/geosparql# asWKT A unit of measure, or unit, is a particular quantity value that has been chosen as a scale for measuring other quantities the same kind (more generally of equivalent dimension). For example, the meter is a quantity of length that has been rigorously defined and standardized by the BIPM (International Board of Weights and Measures). Any measurement of the length can be expressed as a number multiplied by the unit meter. http://qudt.org/schema/qudt/ Unit A customary logarithmic measure most commonly used (in various ways) for measuring sound.Sound is measured on a logarithmic scale. Informally, if one sound is (10 decibels) "louder" than another, this means the louder sound is 10 times louder than the fainter one. A difference of 20 decibels corresponds to an increase of 10 x 10 or 100 times in intensity. http://qudt.org/vocab/unit/ dB "Decibel Referred to 1mw" is a 'Dimensionless Ratio' expressed as dBm. http://qudt.org/vocab/unit/ dBm HZ is the SI unit of frequency defined as the number of cycles per second of a periodic phenomenon. One of its most common uses is the description of the sine wave, particularly those used in radio and audio applications, such as the frequency of musical tones. The word is named for Heinrich Rudolf Hertz, who was the first to conclusively prove the existence of electromagnetic waves. http://qudt.org/vocab/unit/ Hz A unit of power equal to one thousandth of a watt. http://qudt.org/vocab/unit/ mW The attenuation rate is a simplified, summed value representing the reduction in intensity of electromagnetic waves as they pass through a building element. It quantifies the loss of energy due to absorption. http://w3id.org/cno# AttenuationRate Direction characterizes the pattern in which an antenna radiates or receives signals. Typical types include omnidirectional antennas, which radiate equally in all directions, and directional antennas, which focus the signal in a specific direction for increased range and performance. http://w3id.org/cno# Direction Directionality refers to an antenna's ability to focus the signal in a specific direction, enhancing signal strength and range in that direction while minimizing it in others. http://w3id.org/cno# Directional Frequency is the number of occurrences of a repeating event per unit time, measured in Hertz (Hz). http://w3id.org/cno# Frequency Gain is a measure of an antenna's ability to direct or concentrate radio frequency energy in a particular direction, expressed in decibels (dB). http://w3id.org/cno# Gain Material is a class used to describe the relevant properties affecting radio wave propagation. http://w3id.org/cno# Material 1 1 Obstacles describe any physical object or material that can impede, reflect, scatter, or absorb radio waves, thereby affecting signal strength and propagation. Obstacle Omnidirectionality refers to an antenna's ability to radiate or receive signals uniformly in all horizontal directions, providing 360-degree coverage http://w3id.org/cno# Omnidirectional Position refers to the specific location or coordinates of an antenna in a given space. http://w3id.org/cno# Position Power refers to the amount of energy transmitted or received by an antenna per unit time, measured in milliwatts (mw). http://w3id.org/cno# Power 1 1 1 An antenna is the interface between radio waves propagating through space and electric currents moving in metal conductors. Antenna The generic class process serves as the central element of the construction process ontology. It can represent a classical process or a subfield common in some definitions such as an activity or a task. Due to the problem of the subjectivity of classifications of the term, no further distinction will be made here. http://w3id.org/ioc# Process A Material according to the IFC4 ifcOWL ontology https://standards.buildingsmart.org/IFC/DEV/IFC4/ADD2_TC1/OWL# IfcMaterial Element - Constituent of a construction entity with a characteristic technical function, form or position [[ISO-12006], 3.4.7]. http://w3id.org/bot# bot:Element Conductor is a subclass of material known for its high electrical conductivity, causing significant absorption and reflection of radio waves, which leads to substantial signal attenuation. http://w3id.org/cno# Conductor Dielectric is a subclass of material that does not conduct electricity but affects radio wave propagation by allowing waves to pass through with reduced speed and minimal signal loss due to its ability to store electrical energy. http://w3id.org/cno# Dielectric A receiver is a device that captures incoming radio waves and converts them back into electrical signals for processing. http://w3id.org/cno# Receiver 1 1 A transmitter is a device that converts electrical signals into radio waves and radiates them into the surrounding environment. http://w3id.org/cno# Transmitter "Abstract node for geometry that should not contain geometry descriptions (neither RDF-based or text-based). This node can be used to attach additional information to the information as author, time of creation, geometry context or dependencies with other geometry descriptions as transformations, complementations or derivations. By creating subclasses of this class for specific types of geometry descriptions (e.g. OBJ, GEOM, glTF), more informational value can be added and used in querying for specific geometry description formats."@en ; https://w3id.org/omg# Geometry
