Method for Wireless Transmission of Data Between Multiple Network Nodes of a Communication Network and Network Node of a Communication Network for Wireless Transmission of Data

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method and network nodes for wireless data transmission within a communication network, allowing direct data exchange (i.e., not via an access node or infrastructure AP) between nodes that remain in their original configuration modes, such as infrastructure or ad-hoc modes (e.g., per IEEE 802.11). It introduces an additional 'second communication mode' that works alongside existing modes and enables network nodes in different standard modes to exchange data directly by utilizing specialized data frames layered onto the standard network stack. This avoids the need for system-level mode switching or administrative reconfiguration, providing more seamless and flexible wireless networking.

Use CasesContent extracted from patent full text and abstract with AI.

• File and media sharing directly between laptops, PCs, or mobile devices on the same wireless network without relying on the Wi-Fi router/AP.
• Enterprise or school networks that require ad-hoc peer-to-peer communication for collaboration or rapid data exchange without infrastructure changes.
• IoT device networks facilitating direct device-to-device communication while still maintaining connectivity to cloud or back-end infrastructure.
• Disaster recovery scenarios, where APs/infrastructure may be unavailable, but devices need to communicate directly for data exchange or coordination.
• Dynamic group communication applications, such as gaming or local content distribution, where membership and data sharing should occur directly and flexibly between group members.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables direct peer-to-peer (ad-hoc) communication between devices without requiring disruptive reconfiguration of network nodes.
• Supports parallel direct and infrastructure data flows—devices can perform both without mode switching.
• Reduces administrative overhead and prevents the need for privileged access to change device modes, improving usability and flexibility for ordinary users.
• Facilitates direct, secure data exchange within defined ad-hoc groups via group identification and multicasting, benefiting collaboration and private sharing.
• Maintains compatibility with standard wireless protocols (like IEEE 802.11), allowing easy deployment on existing hardware.
• Improves network resilience and adaptability, especially important in environments with fluctuating access node availability or changing group memberships.

Patent Abstract

A method for wirelessly transmitting data between a plurality of network nodes (A1, A2, B1, B2) of a communication network, wherein a configuration of at least one of the network nodes (A1, A2) is carried out such that said node is in a first communication mode, in which it can transmit data via an access node (AP) of the communication network to another network node (A2, A1). In addition, a second communication mode is provided between the network nodes (A1, A2, B1, B2), in which data is transmitted directly, which is to say not via the access node (AP), between the network node (A1, A2) configured in the first communication mode and at least one other network node, while the network node (A1, A2) configured in the first communication mode remains in the first communication mode. To this end, frames, into which the data to be directly transmitted are packed, are generated in the second communication mode and placed on the data backup layer, which is used for the first communication mode.
