Radiation Imaging Antenna Selection for Stable Wireless LAN
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiation imaging apparatuses face issues with unstable wireless communication due to the dynamic switching of antennas, leading to downtime and reduced usability when non-optimum antennas are selected based on variations in received signal strength indicator (RSSI) values.
Innovation Solution
A radiation imaging system with a control apparatus that determines the most suitable antenna for wireless communication by considering the radiation imaging system's environment and location, using information such as received signal strength indicator (RSSI), signal-to-noise ratio (SNR), and data rate, and transmits this information to the radiation imaging apparatus to ensure stable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If antennas are dynamically switched based on RSSI values, then wireless communication adaptability is improved, but communication stability deteriorates due to non-optimum antenna selection and downtime
Solution Approach 1:
The control apparatus performs preliminary actions by determining the optimal antenna before wireless communication actually starts. The control apparatus obtains information about the radiation imaging system, determines at least one antenna to be used based on this information, and transmits the determined antenna information to the radiation imaging apparatus in advance, preventing communication instability caused by dynamic switching during operation.
2Adaptability or versatility
If dynamic antenna switching is implemented, then communication environment adaptability is improved, but system downtime increases due to antenna reselection
Solution Approach 1:
The optimal antenna is determined in advance before communication operations begin. The control apparatus obtains system information, determines the appropriate antenna based on this information, and transmits the determination result to the radiation imaging apparatus beforehand, eliminating the need for time-consuming antenna reselection during communication operations.
3Ease of operation
If antenna selection is based on RSSI variations, then initial communication setup is simplified, but communication reliability deteriorates due to signal fluctuations
Solution Approach 1:
The control apparatus acts as an intermediary between the radiation imaging system and the antenna selection process. It obtains information about the radiation imaging system, determines the appropriate antenna based on this information, and transmits the determination result to the radiation imaging apparatus, thereby mediating the antenna selection to ensure both simplicity and reliability.
