Wireless Access Point Beacon Transmission Grouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, when a large number of mobile devices transmit beacons simultaneously, the receiver often loses or repeats beacons due to limited bandwidth and buffer constraints, leading to inefficiencies in data reception.
Innovation Solution
A transmission method where a wireless access point device receives and broadcasts packages to mobile devices, sorting them into groups based on reception status, with the first group stopping transmission after confirmation and the second group continuing to transmit until successful receipt, optimizing resource distribution and reducing losses.

Engineering Contradiction Analysis
1Quantity of substance
If a large number of mobile devices transmit beacons simultaneously, then the quantity of beacons transmitted increases, but the receiver loses or repeatedly receives beacons due to limited bandwidth and buffer constraints
Solution Approach 1:
The patent segments the transmitting mobile devices into multiple groups based on their beacon transmission timing. Devices are divided into different transmission slots or time windows, so that not all devices transmit simultaneously. This segmentation reduces the instantaneous transmission load on the receiver, preventing buffer overflow and packet loss while maintaining high overall transmission quantity across all groups.
Solution Approach 2:
The patent implements periodic transmission cycles where mobile devices transmit beacons in structured time intervals rather than continuously or randomly. By organizing transmissions into periodic slots with controlled intervals, the system manages the quantity of beacons transmitted while ensuring the receiver can process each batch reliably, thus resolving the contradiction between high transmission volume and reception reliability.
2Productivity
If all mobile devices transmit beacons continuously, then the rate of beacon transmission increases, but the receiver cannot process all beacons leading to repeated receptions and data redundancy
Solution Approach 1:
The patent applies preliminary action by having mobile devices check whether their beacon data has already been received by the system before transmitting. The receiver maintains information about previously received beacons, and transmitters query this information to avoid redundant transmissions. This preliminary check mechanism maintains high transmission productivity while eliminating data redundancy and preventing information loss through repeated receptions.
Solution Approach 2:
The patent implements a feedback mechanism where the receiver provides acknowledgment information back to transmitters about which beacons have been successfully received. Mobile devices use this feedback to determine whether to transmit new beacons or wait for the next transmission opportunity. This feedback loop optimizes the transmission rate by preventing redundant sends while ensuring all necessary beacons are delivered, thus resolving the contradiction between productivity and information loss.

AI summary
A transmission method is applied to a wireless communication system including at least one wireless access point device and a plurality of mobile devices, each mobile device correspondingly generating a first package. The transmission method includes: the wireless access point device receiving a part of the first packages of the mobile devices; the wireless access point device broadcasting a second package to the plurality of mobile devices; and each mobile device being sorted to a first group mobile device or a second group mobile device according to the second package, the first group mobile device stopping transmission of the first package to the wireless access point device and the second group mobile device continuously transmitting the first package within a time period after broadcasting the second package.
