Solution Overview

Problem

There is a need for efficiently facilitating communications in wireless communication devices that operate over both IEEE 802.11 WLAN infrastructure connections and Wi-Fi Peer-to-Peer (P2P) connections, particularly in environments requiring concurrent and seamless data transfer without infrastructure traversal.

Innovation Solution

A wireless communication device is configured with a first wireless transceiver for IEEE 802.11 WLAN-STA connections and a second wireless transceiver for Wi-Fi P2P connections, using distinct Media Access Control (MAC) addresses for each type of connection, allowing concurrent operation and efficient data transfer between different wireless networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a wireless device uses a single transceiver for both WLAN infrastructure and Wi-Fi P2P connections, then device complexity is reduced, but communication efficiency and reliability deteriorate due to inability to maintain concurrent connections

Engineering Contradiction:

Improvetransceiver configurationVSAvoidconcurrent connection reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent divides the wireless communication functionality into separate transceivers: a first transceiver dedicated to WLAN infrastructure connections and a second transceiver dedicated to Wi-Fi P2P connections. This segmentation allows each transceiver to operate independently without interference, enabling reliable concurrent connections while maintaining clear functional boundaries between different communication modes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements multi-functionality by enabling the wireless device to simultaneously maintain both WLAN infrastructure connections and Wi-Fi P2P connections through separate transceivers. Each transceiver is specialized for its specific function, yet together they provide universal communication capability across different network types, allowing the device to adapt to various communication scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a wireless device maintains concurrent WLAN and Wi-Fi P2P connections, then communication versatility is improved, but power consumption increases due to both transceivers operating simultaneously

Engineering Contradiction:

Improveconnection type versatilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic transceiver management where the wireless device can selectively activate or deactivate transceivers based on current communication requirements. The system dynamically switches between using the first transceiver for WLAN infrastructure connections, the second transceiver for Wi-Fi P2P connections, or either transceiver for ad-hoc connections, thereby reducing power consumption by keeping only the necessary transceiver active at any given time.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the operational parameters of the transceivers by allowing flexible assignment of connection types to either transceiver. The system can modify which transceiver operates in which mode (WLAN infrastructure, P2P, or ad-hoc), enabling parameter optimization for power efficiency while maintaining versatility in connection capabilities.

Inventive Principle:

3Reliability

If a wireless device uses distinct MAC addresses for different connection types, then communication reliability is improved, but device complexity increases due to additional address management

Engineering Contradiction:

Improveconnection identification accuracyVSAvoidaddress management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the addressing function by assigning distinct MAC addresses to different transceivers: a first MAC address for the first transceiver handling WLAN infrastructure connections and a second MAC address for the second transceiver handling Wi-Fi P2P connections. This segmentation ensures clear identification and routing of communications while simplifying address management through transceiver-specific addressing.

AI summary

A wireless communication device includes a first wireless transceiver and a second wireless transceiver. The wireless device is configured for communicating via the first transceiver over a first connection with a first device, where communications to and from the wireless device are addressed with a first hardware address assigned to the first transceiver. The wireless device is further configured for communicating via the first transceiver over a second connection with a second device, where communications to and from the wireless device are addresses with a second hardware address assigned to the second transceiver. The first transceiver may be configured for communications in accordance with IEEE 802.11, and the second transceiver may be configured for communications in accordance with BLUETOOTH®. The first connection may be a wireless local area network (WLAN) infrastructure connection, and the second connection may be a WiFi Peer-to-Peer (P2P) connection.
