Telecom companies can benefit enormously from accurate 3D maps when planning to roll out 5G networks and need to know about the density and height of buildings in large areas (as well as other obstacles such as trees and topography). This information can help identify the best location for cell towers.  

Let's delve into the key aspects that make 3D nationwide coverage a transformative leap in connectivity:

1. Precision in Network Planning:

3D mapping technology provides unparalleled precision in the planning and deployment of wireless networks. By incorporating detailed 3D models of cities, towns, and rural areas, telecommunication companies can strategically position antennas and base stations to optimize signal strength and coverage. This precision ensures efficient utilization of resources and enhances the overall performance of the network.

Precise and up-to-date geodata ensure the relevant information to estimate all the possible outcomes and make a better decision.

Our 3D BUILDINGS AND 3D TREES provide a high level of detail, in both urban and rural areas. 3D data creates a complete digital twin of the country along with other layers of geodata used for regional planning:

• Street-road networks
• Railways
• 3D Bridges
• Terrain
• Hydrography
• Land use
• Population density
• Geodata is delivered in the formats of most GIS and radio planning tools.

2. Enhanced User Experience:

The shift to 3D nationwide coverage is not only about technical advancements but also about improving the end-user experience. With a more accurate representation of the environment, users can expect seamless connectivity and enhanced services. Whether in urban jungles or remote landscapes, 3D coverage ensures a consistent and reliable connection for users across the nation.

3. Addressing Topographical Challenges:

Traditional coverage models often struggle to address topographical challenges, especially in regions with varied landscapes. 3D mapping technology, powered by advanced algorithms, can adapt to diverse terrains, providing optimized coverage even in geographically complex areas. This adaptability is crucial for achieving comprehensive nationwide coverage.

Our research and development teams have combined our GIS expertise with advances in artificial intelligence. This combination provides a tool that makes it easy, fast, and cost-effective to create 3D models of cities, towns, villages, and even remote areas – anywhere on Earth.

4. Future-Proofing Connectivity:

• Disaster recovery
• Environmental management

3D GEODATA FOR SOLAR RESOURCE ASSESSMENTS

Solar energy is used worldwide and currently, we are witnessing an increasing trend in its usage for generating electricity and heating/desalinating water.

Today, Photovoltaics (PV), also called solar cells, is one of the fastest-growing renewable energy technologies and is ready to play a major role in the future global electricity generation mix.

Solar PV installations can be combined to provide electricity on a commercial scale, or arranged in smaller configurations for mini-grids or personal use. Using solar PV to power mini-grids is an excellent way to bring electricity access to people who do not live near power transmission lines, particularly in developing countries with excellent solar energy resources.

SOLAR ROOF PV POTENTIAL MODELLING

Solar resource assessments are a core method for developing and deploying solar energy plants. In turn, 3D buildings and 3D vegetation are key initial sources for evaluating solar resource availability and running solar energy simulations.

High-accuracy 3D datasets provide high solar project value and increase its performance. Precise and up-to-date geodata ensures the relevant information to make a better decision. Data details, accuracy, and relevance are critical parameters for solar resource assessment and modeling.

LOD3 3D buildings manufactured by Visicom for solar energy projects involve such small elements as roof furniture, elevator shafts, towers, spires, and also sloping roof elements.

The assigned parameters:

• azimuth
• tilt angle
• area of flat parts
• roof height

are calculated for each element separately, creating the background for producing solar rooftop maps (solar cadaster). The high accuracy of the building elements' footprints is tailored specifically to the estimation and calculation of the solar energy potential for each roof.

SAMPLE OF DATA FOR ROOF SURFACES

PREVIEW OF FINAL BUILDINGS DATA

To create a 3D data set for large areas where solar stations are planned to be installed, LIDAR data are used among other sources. It is possible to achieve completeness and precision of ≥85% if the density of LIDAR points is more than 8 per one sq.m, and ≥90% if the density of LIDAR points is more than 15 per one sq.m. Due to the precise setting of the threshold coefficients used in the recognition of obstacles, our LIDAR processing algorithm allows us to recognize buildings and the main elements of roofs, allocate tree crowns, and restore the structure of buildings closed by crowns. After recognition and vectorization, the necessary attributes of roofs, heights, area, and slope of the roof elements are assigned to the buildings and trees.

Automation of the process of buildings recognition allows us to quickly produce high-quality 3D data sets for large territories in urban and suburban areas.

VISICOM AND 5G: BIG NEW GENERATION

WHY IT IS IMPORTANT TO TAKE INTO ACCOUNT ALL 5G REQUIREMENT CREATING DIGITAL MAPS

5G (fifth generation) it is the abbreviated name of the fifth-generation mobile communication, which is able to replace the present 3G and 4G. This abbreviation hides a whole set of technologies, many of them are still under construction. The completion of the testing part and approval of standards is anticipated prior to 2020.

The implementation of the fifth generation of mobile networks guarantees to become a revolutionary breakthrough in communications because of subsequent innovations:

• New ranges
• Network slicing
• D2D (Device-to-device)
• Massive MIMO Technology

VISICOM'S GEODATA

Company Visicom creates its own maps taking into considering all the features of the fifth generation of telecommunication networks. 3D maps for 5G planning - this is the type of maps that produced specifically for the fifth generation of networks, inside of cities. 

5G network planning in suburban areas near the big megapolises and rural areas has faced new challenges that have an effect on planning processes. In order to meet the extended requirements regarding map accuracy, we propose to upgrade existing 2D into 2.5D Models with additional Clutter Height Layer.

At higher frequencies (including the mmWave bands), the signal propagation is greatly impacted by manmade and natural obstacles, therefore, the usage of cmWave and mmWave frequencies is an important component of 5G technology.

Our geodata portfolio includes over 1500 cities across 120 + countries.

5G AND GEOSPATIAL DATA

Prediction of radio wave propagation with Wireless InSite propagation model – a product of our partners Remcom (https://www.remcom.com/wireless-insite-em-propagation-software) – based on the Visicom 3D model tailored to 5G.

Bearing the development of telecommunication industry in mind, it is most certainly that in the nearest future a huge amount of various devices will be available online providing multimedia services, alternate/augmented realities, IoT solutions. Such innovations are already featured many aspects of human activities; further, they will become part of our ordinary life:  transport, energetics, healthcare, manufacturing, business, public safety etc.

Currently, the radio-planning processes are in progress serving as a foundation for 5G-networks widespread implementation and ensuring their dynamic development. Global mobile operators and vendors swiftly move from testing and trials to launching, generating new rules and technical requirements, simultaneously reducing the costs.

The main benefit of 5G networks is their ability to carry an enormous amount of data, which is possible due to high-frequency radio waves they are based on. On the other hand, such mm-wave frequencies are substantial impacted when they face either small obstacles. 3D Geodata as a model describing the environment serve as a basis for 5G planning. Because of the sensitivity of radio waves it is necessary to have an adequate level of maps detalization, which tends to grow – buildings are described with roofs features, pipes, air conditioners, spires, sloping roofs; vegetation, which also can affect the signal propagation, is represented starting from solid bodies with average height to 3D separate trees with crown and trunk features. All these trends motivate geodata providers to invest more into R&D creating new technologies for 3D data processing; to design deep neural networks; to implement machine learning architectures for satellite image classification, segmentation, and comprehensive automation of all obstacles processing and visualization.

The geodata suppliers are promptly adopting to the growing demands announcing the extending production capabilities and technologies. On the other hand, the amount of such detailed 3D data is increasingly enhancing, thereby outpacing the potential of planning tools to handle them. Now some tool vendors are actively working on this, so, once the new advanced algorithms are available, the next great stage in 5G planning enabling ultra-high speed and ultra-low latency will be in service.

5G will make networks several times faster, increase networks capacity, open possibilities to cover not only dense built-up territories in cities but suburbs and villages, and it will really unlock the potential of IoT and smart cities development, connecting all people and all things.

“The most interesting things in this way are all new possibilities and services, that we are not able to predict yet” – said the CEO of geodata provider company VISICOM (Ukraine), Dr. Volodymyr Kolinko – “and our company is ready to support all aspects of new generation networks development, since geospatial data and mobile networks are of crucial importance to each other and to their mutual future”.
