Solution Overview

Problem

Wireless LAN operators face challenges in securely broadcasting information to customers while maintaining network security, as existing methods require either maintaining separate networks, providing access credentials, or forgoing wireless information distribution.

Innovation Solution

A system where a wireless access point periodically broadcasts a beacon with a data file, including information like store maps or coupons, allowing receiving devices to store the data without establishing a connection, using a processor to determine if a threshold of repeated transmissions is met, ensuring secure and efficient distribution of information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the wireless LAN is secured to prevent general public access, then network security is improved, but the ability to provide information wirelessly to customers deteriorates

Engineering Contradiction:
Improvenetwork securityVSAvoidinformation distribution capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the wireless communication functionality into two distinct modes: a secured network mode for authenticated devices and a broadcast mode for public information distribution. The access point separates the control plane (requiring authentication) from the data plane (allowing open broadcasts), enabling simultaneous network security and information distribution capability without requiring separate physical networks.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If two separate networks are maintained (one secure, one public), then network security and information distribution are both satisfied, but device complexity increases

Engineering Contradiction:
Improveinformation distribution capabilityVSAvoidnetwork management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The access point is designed with multi-functionality, serving both as a secured network gateway and an open broadcast transmitter. The same hardware infrastructure performs dual roles: establishing authenticated connections for network access while simultaneously broadcasting information to all devices in range. This eliminates the need for separate physical networks while maintaining both security and information distribution functions.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If access credentials are provided to customers, then information distribution is enabled, but network security deteriorates

Engineering Contradiction:
Improveinformation distribution capabilityVSAvoidnetwork security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent extracts the information distribution function from the authenticated network access function. Instead of requiring customers to join the secured network to receive information, the system separates these functions by broadcasting information over an open channel that does not require authentication. This extraction allows information distribution without compromising network security, as the broadcast channel remains independent of the authenticated network.

Inventive Principle:
Principle #2Taking out (Extraction)

4Adaptability or versatility

If one unsecured network is maintained for both business and general public use, then information distribution is improved, but network security deteriorates

Engineering Contradiction:
Improveinformation distribution capabilityVSAvoidnetwork security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the communication protocols into two distinct layers: a secured layer for network access control and an open broadcast layer for information distribution. The access point simultaneously operates both layers, with the broadcast layer transmitting information packets that any device can receive without authentication, while the secured layer maintains network access restrictions. This segmentation enables unsecured information distribution within an otherwise secured network infrastructure.

Inventive Principle:
Principle #1Segmentation

AI summary

An apparatus includes a communications interface configured to receive a transmission from a wireless device. The transmission may include a beacon message and a date file. The apparatus may further include a memory device and a processor. The processor may be configured to determine whether a threshold is satisfied based on whether additional transmissions including the data file are received from the wireless device. The processor may be further configured to cause the memory device to store the data file in response to determining that the threshold is satisfied.
