Wi-Fi Charging Access Point Channel Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging multiple mobile devices over a Wi-Fi network can cause network congestion and slow down data transmission due to the simultaneous transmission of charging packets alongside data packets.
Innovation Solution
Implementing a method where access points detect and categorize chargeable devices into fully charged and need-charging groups, using separate channels for data and charging packets to manage traffic efficiently, thereby preventing congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple mobile devices are charged simultaneously over Wi-Fi network, then charging capability is improved, but network congestion occurs and data transmission speed decreases
Solution Approach 1:
The patent segments the Wi-Fi network traffic into separate channels: one channel dedicated to data transmission and another channel dedicated to charging packet transmission. This segmentation allows simultaneous data communication and device charging without mutual interference, resolving the contradiction between improving charging capability and maintaining data transmission speed.
2Productivity
If charging packets are transmitted alongside data packets, then device charging is enabled, but network congestion is caused
Solution Approach 1:
The patent introduces a new dimension in the network communication protocol by creating separate transmission channels for charging packets and data packets. This dimensional separation in the protocol structure allows both types of traffic to coexist without competing for the same network resources, thereby enabling device charging while preventing network congestion.
3Ease of operation
If Wi-Fi network is used for charging, then wireless charging is achieved, but network performance deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of a dedicated charging packet channel that mediates between the charging function and the data transmission function. This intermediary channel ensures that charging operations can be performed wirelessly without directly interfering with data transmission, thus maintaining network performance while enabling wireless charging.

AI summary
Embodiments include methods, systems, and computer program products of a Wi-Fi charging system. An example Wi-Fi charging system includes a plurality of chargeable devices (CD) configured to be charged wirelessly. The plurality of chargeable devices is grouped into a fully charged group, and a need-charging group according to a charging status of each of the plurality of chargeable devices respectively. The Wi-Fi charging system also includes at least one access point (AP) that wirelessly charges the chargeable devices using a Wi-Fi communication network. The access point uses a first AP channel to transmit a plurality of data packets to the chargeable devices in the fully charged group, and a second AP channel to transmit a plurality of data packets and a plurality of charging packets to the chargeable devices in the need-charging group.
