5G Propagation model
Ray-tracing Propagation models: This model is established upon high-precision electronic maps and multipath modeling which plays an important role in 5G network planning. The beam-based ray-tracing propagation model includes the features as a) Direct radiation: the transmitter and receiver are not affected by tall buildings or dense vegetation. b) Reflection: when it occurs, the incident ray, reflected ray, and reflection point is at the same point. c) Diffraction: the condition of diffraction is related to the wavelength of the electromagnetic wave and the size of the obstacle edge. d) Signal transmission: the transmission energy is related to the dielectric constant and permeability of the material. e) combined paths: the transmission mode of multiple paths combined can be marginalized.
UMI and UMA Propagation Models: The high-frequency and experience-centric propagation model does not include environmental features. To develop a high-frequency propagation model featuring high efficiency and accuracy. It includes important aspects such as the height coefficient of the receiver/transmitter.
Refined coverage prediction
Coverage prediction is the most commonly used approach to evaluate network coverage, as well as the foundation of network planning. It is capable of simulating the network coverage for various 5G services like eMBB (enhanced Mobile Broadband), etc. It covers coverage in frequency bands (3.5/4.5/28/39 GHz), it also covers outdoors, etc. It supports propagation models like the Ray-tracing model, UMI and UMA propagation models, static beamforming, and dynamic beamforming of Massive MIMO, signal level, interference, signal quality, and uplink and downlink throughput of the pilot, broadcast, control and traffic channels, coverage prediction after the penetration loss caused by an unspecified number of materials.
3D Coverage Prediction
In the future, mostly the traffic generated is indoor data traffic. 3D coverage prediction function can extend the simulation range from a 2D plane to a 3D space. In this, multiple coverage indicators are displayed: 3D space modeling which uses an electronic map providing important information for large structures, 3D propagation model - 3D simulation, and 2D outdoor simulation are different in terms of radio signal propagation. Under 3D prediction - signal level, interference, signal quality, throughput as well as various traffic channels are predicted in the 3D scenarios.
Automatic Cell planning
Massive MIMO (Multiple Input Multiple Output) is one of the main features of the 5G technology. Massive MIMO groups together antennas at the transmitter and the receiver to provide better throughput and spectral efficiency. Massive MIMO antenna beams are classified into static and dynamic beams. 5G static broadcast beams cover the entire cell using the narrow beams which are transmitted over proper time and frequency resources. Dynamic beams can be configured based on the coverage scenarios. ACP solution can help in the planning the massive MIMO antenna beam patterns by:
- It can accurately identify the building scenarios which are based on high-precision digital maps.
- It can determine the height, angle, and azimuth of massive MIMO antennas after collecting various statistics.
- It can generate the best set of RF and BF parameters for new sites.
5G Radio Propagation modeling
Radio propagation provides the best way to provide the best support for 5G propagation scenarios: based on true 3D ray tracing/launching algorithms, supports 5G spectrum for multi-layer 5G networks, it is integrated with building material electromagnetic property, supports MIMO, multi-user MIM) and 3D MIMO, it works in indoor, indoor to outdoor and outdoor to indoor scenarios.
Planning a new network with mmWave frequencies has its different challenges as the signals get easily obstructed which creates problems for the network planners to plan the network. With Planning Automation, network planners gain an up-to-date view of the dynamic, multi-technology network and can ensure that all the content changes do not interfere with each other or it will impact the service quality of experience. It has several benefits like :
- Extensive 5G capabilities
- Advanced Network Modeling
- OSS Integration
- Highly Automated
- Global reach and local support
- A future proof investment
Accurate Site Planning
In the 5G era, more sites are growing and also densely deployed. Accurate Site planning solutions will help to reduce the construction costs of the network. This solution will help in selecting new sites to realize the network construction objectives like coverage and throughput. This solution supports site-level and sector-level planning based on various values and scenarios.
