Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems with multiple radio base stations operating in the 2.4 GHz band experience interference and high investment costs due to the need for separate components for each access point, leading to inefficient infrastructure and potential interference in radio communication.
Innovation Solution

Engineering Contradiction Analysis
1Reliability
If multiple separate radio base stations are deployed to serve different groups of radio communication devices, then each group can have dedicated radio communication, but interference occurs between access points operating in the same frequency band and investment costs increase due to separate components for each access point
Solution Approach 1:
The patent combines multiple radio modules (first radio module for WLAN communication and second radio module for radio frequency identification communication) into a single radio base station. This merging allows both communication types to share common infrastructure components while the radio modules are coupled to enable them to influence each other's radio activity, thereby preventing interference between the different communication groups.
2Reliability
If multiple separate radio base stations are deployed to serve different groups of radio communication devices, then each group can have dedicated radio communication, but infrastructure costs increase due to separate power supply, computer modules, and electrical connections for each access point
Solution Approach 1:
The patent merges multiple radio modules into a single radio base station that shares common infrastructure including power supply, computer module, and electrical connections. This reduces the overall number of components needed and simplifies the infrastructure while maintaining dedicated communication channels for different device groups through the coupled radio modules.
Solution Approach 2:
The single radio base station is designed to perform multiple functions by housing both the first radio module for WLAN communication and the second radio module for radio frequency identification communication. This multi-functional design allows one base station to serve multiple communication purposes that would traditionally require separate dedicated access points.
3Ease of operation
If radio modules operate independently without coupling, then each module can operate autonomously, but interference occurs between the radio modules when they operate in the same frequency band
Solution Approach 1:
The patent establishes a coupling between the first radio module and the second radio module that enables feedback mechanisms. Each radio module can detect radio activity and influence the other's operation, allowing them to coordinate their transmissions and avoid simultaneous operation in the same frequency band, thereby preventing interference while maintaining autonomous operation capabilities.

AI summary
The invention relates to a base station or a radio access point having a plurality of radio modules, of which one communicates with electronic price indication signs. If a plurality of radio modules use the same frequencies and communicate simultaneously, disturbances can occur in the form of interference. The invention solves this problem in that the radio modules (21, 22, 23) are coupled (24) such that a radio module (22) can influence another radio module (21, 23) with regard to the radio activity of said other radio module. In particular, the radio module that communicates with the electronic price indication signs (22) can silence the other radio modules (21, 23) by means of a radio activity control signal (FS).
