Urban 2.5D/3D Telecom Models (Digital Maps of Terrain) - this is detailed planning of telecommunication networks in urban areas with dense development, where all objects of urban infrastructure potentially obstructing the propagation of radio waves are displayed.

Regional 2D Telecom Models (Digital Maps of Terrain) - this is the design of telecommunication networks covering large territories.

The composition of Telecom digital terrain models includes:

  • Vector 3D/2.5D/2D Model
  • Clutter 3D/2.5D/2D Model
  • Digital 3D/2.5D/2D Relief Model
  • Digital 3D/2.5D Model of Obstacle Heights
  • Orthophoto plans;
  • Address database

Purposes of Telecom Models

Telecom models (digital maps of terrain) are used for the purposes of planning, optimization, deployment, and operation of cellular radio communication networks and broadband access like Wi-Fi and WiMAX.

Detailed planning of telecommunication networks in urban areas with dense development, displaying all objects of urban infrastructure that potentially obstruct the propagation of radio waves. Providing accurate and cost-effective modeling of obstacle heights over large areas, both in urban and integrated planning processes within and beyond cities.

For regional planning, these models are used for large-scale planning of radio networks and are an ideal option for use in rural areas, at the initial stage of planning, or for nominal planning.

To address the issue of designing 3G/4G/LTE networks outside cities, height values are added to buildings and vegetation features in suburban and rural areas.

For planning new 5G networks and enhancing the 4G telecom industry for all territories from regions to city centers, precise geodata with high resolution are necessary for:

  • Planning next-generation networks

  • Line of sight analysis

  • Traffic flow modeling

  • Population distribution modeling
Applying highly accurate and up-to-date cartographic base data (CMM) for radio network coverage calculation (process of planning and optimizing the positioning of cellular base stations) leads to:
  • Infrastructure cost optimization (CAPEX, OPEX),
    and, consequently,
  • Improved communication quality (increased customer base, increased ARPU (Average revenue per user)).

Advantages of Using Remote Sensing Data

Remote sensing data of very high and high resolution can be obtained more quickly as they may already be available in the operator's archives, and new imaging does not require any approvals from competent authorities. Suitable for creating 2D models (regional models).

Satellite imagery does not require on-site visits, unlike aerial photography and UAV-based imaging.

Aerial photography allows obtaining images with high spatial resolution (up to 1 cm/pixel) and provides a higher level of detail for orthophotoplans and models, achieving a root mean square error (RMSE) of coordinate determination of less than 10 cm, and can be performed below solid cloud cover. Aerial photography is suitable for creating highly accurate CMM and CMR. Suitable for creating 3D and 2.5D models (urban models).

  • the territory of interest (location / coordinates of the object in any convenient form, and the area of the object);
  • a specific task that needs to be solved with the use of CMM
  • As the main material for creating (updating) the data project, remote sensing materials available in the archives of spacecraft operators for the most current date are used, or a new survey is ordered. High accuracy of all parameters is ensured through the use of stereo pairs of high-resolution satellite images and ultra-high-resolution UAV data or aerial photography.
  • When creating (updating) a data project, additional and reference materials are used in the form of various geographical descriptions, maps and atlases of a larger (small) scale, reference books, as well as data available to the Customer.
  • Cartographic products available in public and private funds or cartographic products provided by the Customer can be used as updated telecom models.

Data is provided in formats specified by the Customer according to the requirements of the technical assignment and compatible with ASSET, ATOLL, Mapinfo, and other software (as per the customer's requirements).

The recommended software for using CMM is the ONEPLAN solution.

5G networks operate in the range of centimeter and millimeter waves (cmWave/mmWave). They are located in the high-frequency spectrum and have an advantage due to the possibility of transmitting a large amount of data. However, they are also more easily absorbed by gases in the air, trees, foliage, nearby buildings and structures. Therefore, high-precision digital terrain models are needed for high-quality network planning, which will describe both the earth's surface and urban infrastructure objects in as much detail as possible. The propagation of radio waves in the 5G frequency range can be significantly influenced by various objects that are not given due attention on standard digital models: poles, bus stops, fences, monuments, advertising stands, pavilions, etc. In addition to the expanded object composition, the digital terrain model should have increased accuracy characteristics: both in the planned position and in height. The qualification selection of objects should also be changed in the direction of increasing the details of the display of urban infrastructure, natural forms and changes in the landscape of a technogenic nature. Digital terrain models describe in detail the elements of terrestrial and urban infrastructure that can be obstacles to the propagation of radio waves: buildings with their individual architectural forms, bridges, engineering structures, communications with increased detail of individual elements, as well as vegetation. Buildings, engineering structures and vegetation have a breakdown by individual heights of their individual elements. All vegetation elements are divided into tiers of their altitude range in such a way that they form a common forest from different heights, without violating the integrity of perception and modeling of its forms. Maximum realism and accuracy is achieved thanks to the high resolution (1 or 2 m).
The clutter model describes the features of the earth's surface and infrastructure that affect the propagation of radio waves. These elements of the earth's surface are grouped into various classes according to the customer's choice: buildings, structures, hydrography, vegetation, road network, etc. The number, composition, numbering, and color of clutters can be modified by agreement.
