# Modeling Wireless Channels for Future 6G Networks > This patent describes a method for creating detailed mathematical models of how wireless signals travel in future 6G networks, covering all types of frequencies and environments. - **Patent:** US 12451984 - **Original title:** 6G pervasive channel modeling method suitable for all frequency bands and all scenarios - **Owner:** Southeast University - **Granted:** 2025 - **Status:** Active - **Times cited:** 0 - **Field:** telecommunications, software, semiconductors ## What it does This patent details a method for creating comprehensive models of wireless communication channels, specifically for 6G networks. It starts by defining the environment, like the frequency band (from sub-6 GHz to terahertz), the type of antennas used, and the placement of devices. Then, it calculates various signal losses, including path loss, shadowing (obstacles), and weather effects. The method models how signals bounce off surfaces (scatterers) to determine their delay, angle, and strength. Finally, it accounts for movement of devices and changes in the environment over time to update these channel models dynamically, ensuring accurate signal transmission and reception. ## What it does NOT cover - Modeling methods that do not account for both large-scale and small-scale fading effects simultaneously. - Channel models that are limited to only specific frequency bands like only sub-6 GHz or only millimeter wave. - Methods that do not consider the spatial consistency of channel parameters. - Models that do not include the 'birth-death' process of signal clusters over time. - Channel modeling for existing 4G or 5G networks that do not incorporate the specific elements defined for 6G. ## The clever bit The innovation lies in creating a unified mathematical framework that can represent complex wireless channel characteristics across vastly different frequency bands and environments, while also dynamically updating these models based on real-time factors like device movement. ## Real-world examples 1. Simulation tools for 6G network design 2. Development of new wireless communication standards 3. Research into terahertz and optical wireless communication ## Why it matters Accurate channel modeling is crucial for designing and optimizing future wireless communication systems like 6G. This patent provides a framework that aims to be universal, covering a wide range of frequencies and scenarios that 6G is expected to encompass, from global coverage to specific high-bandwidth applications. ## Frequently asked questions ### What does Modeling Wireless Channels for Future 6G Networks cover?
