Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radios are fixedly assigned to antennas, then device complexity is reduced and ease of operation is improved, but network capacity and adaptability deteriorate when traffic increases
Solution Approach 1:
The patent implements dynamic radio allocation where radios are not permanently assigned to specific antennas but are dynamically assigned based on real-time traffic conditions. The system monitors channel utilization and automatically reallocates radios from underutilized antennas to overloaded antennas, transforming the static allocation into a dynamic adaptive system that responds to changing network conditions.
Solution Approach 2:
The patent makes radios universal by enabling them to serve multiple antennas rather than being dedicated to a single antenna. Each radio in the shared pool can be assigned to any antenna that requires additional capacity, making the radio resources multi-functional and adaptable to different network conditions and traffic patterns.
2Productivity
If additional hardware is deployed to increase capacity, then network capacity is improved, but cost and device complexity increase
Solution Approach 1:
The patent merges previously separate radio resources into a unified shared pool that serves multiple antennas. By combining the radio resources and implementing a common allocation mechanism, the system achieves better utilization of existing hardware, eliminating the need to deploy additional radios for each antenna and reducing overall hardware requirements.
Solution Approach 2:
The patent changes the allocation parameter from fixed one-to-one mapping to dynamic many-to-many mapping. This parameter change enables the same hardware resources to serve different configurations based on traffic demands, effectively increasing network capacity without adding physical hardware.
3Adaptability or versatility
If multiple air interface standards are supported at each base station, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements universality by enabling radios to support multiple air interface standards (such as GSM, CDMA, TDMA) through software configuration rather than requiring separate hardware for each standard. This multi-functionality allows a single radio to adapt to different standards based on the service requirements and network conditions.
Solution Approach 2:
The patent uses software-based radio implementations that can copy and emulate different air interface protocols. Instead of having separate physical hardware for each standard, the system uses software layers that can replicate the behavior of different radio standards, reducing hardware complexity while maintaining multi-standard support.
