1Measurement precision
If professional surveyors conduct wireless site surveys to design wireless networks, then the communication performance can be verified and designed accurately, but the process becomes time-consuming and expensive
Solution Approach 1:
The patent creates a digital twin (virtual copy) of the physical environment that includes geometric layout, material properties, and radio-frequency characteristics. This virtual model allows wireless network performance to be simulated and verified without requiring physical site surveys, thereby maintaining measurement precision while eliminating time consumption.
Solution Approach 2:
The patent replaces the mechanical process of physical site surveys with computational modeling and simulation. Instead of manually measuring and surveying physical environments, the system uses computer-generated 3D models and radio-frequency propagation simulations to achieve the same verification objectives, significantly reducing time requirements.

3Device complexity
If 2D floor plans are used to represent environments, then the design process can be simplified, but the accuracy of radio-frequency modeling is reduced
Solution Approach 1:
The patent transitions from 2D floor plans to 3D digital twins that capture the full spatial geometry of the environment. This dimensional enhancement allows for accurate modeling of radio-frequency propagation paths, reflections, and obstacles, thereby improving measurement precision while maintaining manageable complexity through automated modeling processes.
Solution Approach 2:
The patent automatically generates the 3D digital twin and extracts geometric and material properties before the wireless network design process begins. This preliminary creation of the comprehensive environmental model eliminates the need for manual surveying and ensures that accurate radio-frequency parameters are available from the outset, improving both accuracy and efficiency.

AI summary
During operation, an electronic device may perform measurements associated with an environment. Then, the electronic device may create a model that represents the environment, where the model specifies a two-dimensional (2D) or a three-dimensional (3D) geometric layout of the environment and/or estimated parameters associated with radio-frequency properties of at least a portion of the environment. Moreover, the electronic device may design a wireless network for use in the environment, where the designing includes determining radio-frequency characteristics in a band of frequencies associated with the wireless network based at least in part on 10 the model, and the wireless network is predicted to achieve one or more target communication-performance metrics. Next, the electronic device may provide the design information associated with the design that specifies the wireless network, where the design information includes one or more wireless-network components and one or more locations of the wireless-network components in the environment.
