Broadcast Device Configuration Message for Wireless Network Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless network protocols fail to efficiently handle communication between a broadcast device and network devices when the broadcast device is outside the transmission range of the network, leading to interference and unacceptably high communication breakdown periods.
Innovation Solution
A method is introduced where a broadcast device transmits a short message containing configuration information to network devices, allowing them to switch from ongoing communication to receiving broadcasted payload data without significant interference, using a transmission frame structure that enables simultaneous communication and data reception.

Engineering Contradiction Analysis
1Productivity
If the broadcast device starts transmitting payload data without prior signalling, then the network devices can receive the transmitted data, but the transmission interferes with the ongoing communication in the wireless network and causes unacceptably high communication breakdown periods
Solution Approach 1:
The broadcast device transmits a preliminary message containing configuration information before transmitting the payload data. This preliminary action allows network devices to prepare for reception in advance, knowing when to switch from ongoing communication to broadcast reception, thereby reducing interference and communication breakdown periods.
Solution Approach 2:
A message containing configuration information acts as an intermediary between the broadcast device and network devices. This intermediary provides advance notice and scheduling information, enabling network devices to coordinate their transition from network communication to broadcast reception, thus minimizing interference.

If the broadcast device is placed outside the transmission range of network devices, then the broadcast device can have higher transmit range, but conventional network protocols cannot handle the communication between the broadcast device and devices in the wireless network
Solution Approach 1:
The communication process is segmented into two distinct phases: a preliminary message transmission phase containing configuration information, and a payload data transmission phase. This segmentation allows network devices to first receive and process configuration information when within range, then switch to receiving payload data when the broadcast device moves outside the normal network range.
Solution Approach 2:
The system changes communication parameters dynamically - initially using conventional network protocols for configuration message exchange when devices are in range, then transitioning to a broadcast mode with different parameters when the broadcast device moves outside the transmission range of network devices.
3Reliability
If network devices spend time synchronizing with the transmitted data after detecting interference, then they can resume communication, but the communication breakdown period becomes unacceptably high
Solution Approach 1:
Configuration information including timing and synchronization parameters is transmitted in advance in the preliminary message. Network devices use this pre-provided information to quickly synchronize when payload transmission begins, eliminating the need for lengthy synchronization procedures after detecting interference.
Solution Approach 2:
The configuration message provides feedback information about the upcoming payload transmission schedule, allowing network devices to anticipate and prepare for the transmission rather than reacting after interference is detected, significantly reducing the communication breakdown period.
