RF繁殖

Site and terrain visualization, propagation model specification and visualization, path loss, TIREM™, Longley-Rice, outdoor and indoor ray tracing

RF propagation describes the behavior of electromagnetic radiation from a point of transmission as it travels through the surrounding environment. The analysis of RF propagation is essential in understanding how electromagnetic waves incur losses from a transmitter to a receiver in different scenarios. You can use propagation models to calculate the coverage, SINR, signal strength, path loss, and link loss between a transmitter and a receiver in basic, urban, terrain, and multipath environments.

特色示例

在地形上规划雷达网络覆盖

在地形上使用传播建模计划雷达网络。DTED Level-1 Terrain数据是针对包含五个候选单位雷达位点的区域进口的。雷达方程用于确定是否可以检测到目标位置，如果使用Longley-Rice传播模型或Terrain Integrated Rough Earth Model™（TIREM™）计算出额外的路径损失。选择最佳的三个地点以检测到地面高度500米的目标。该方案已更新以建模一个目标，该目标的飞行在地面高250米处。两种情况都显示了雷达覆盖图。

计划在地形上的5G固定无线访问链接

使用5G技术在地形上计划固定的无线访问（FWA）链接。FWA是5G的用例，可为有线服务不可用或表现不佳的房屋或企业提供宽带服务。FWA将基站连接到用户的固定无线终端（FWT）[1]。在5G所需的高频下，叶子和天气等路径损失障碍在确定链接成功方面起着重要作用。

5G城市宏观细胞测试环境的SINR地图

Construct a 5G urban macro-cell test environment and visualize the signal-to-interference-plus-noise ratio (SINR) on a map. The test environment is based on the guidelines defined in Report ITU-R M.[IMT-2020.EVAL] [1] for evaluating 5G radio technologies. This report defines several test environments and usage scenarios in Section 8.2. The test environment in this example is based on the urban environment with high user density and traffic loads focusing on pedestrian and vehicular users (Dense Urban-eMBB). The test environment includes a hexagonal cell network as well as a custom antenna array that is implemented using Phased Array System Toolbox™.
