Engineering Contradiction Analysis
1Area of stationary object
If multiple macro base stations are added to expand network capacity, then coverage area increases, but interference among base stations increases and capacity expansion is limited
Solution Approach 1:
The patent segments the base station functionality by separating the transceiver units (TRXs) from the antennas through a distributed antenna system (DAS). This allows multiple TRXs to be centrally located while antennas are distributed throughout the building, enabling capacity expansion without adding multiple separate macro base stations that would cause interference.
Solution Approach 2:
The patent transitions from horizontal deployment of multiple macro base stations across a landscape to a vertical/distributed architecture where a single multi-TRX base station connects to antennas distributed throughout a building's three-dimensional space. This dimensional shift eliminates inter-base-station interference while providing comprehensive coverage.
2Productivity
If conventional pico base stations are deployed to add capacity, then network capacity increases, but infrastructure requirements and installation costs increase for each site
Solution Approach 1:
The patent merges multiple pico base station functionalities into a single multi-TRX base station that serves the entire building through the DAS. Instead of deploying separate pico base stations at multiple locations, one centralized base station with multiple TRXs provides equivalent or superior capacity while reducing overall infrastructure requirements.
Solution Approach 2:
The distributed antenna system serves as a universal infrastructure that can support multiple TRXs and various wireless protocols simultaneously. This multi-functional approach allows a single base station to provide capacity for multiple users and services without requiring separate infrastructure for each pico cell.
3Ease of manufacture
If conventional pico base stations with single transceiver units are used, then installation is simpler, but coverage and capacity are limited especially in indoor environments
Solution Approach 1:
The system provides dynamic capacity allocation where multiple TRXs can be activated or deactivated based on real-time coverage and capacity requirements. The distributed antenna system enables flexible resource allocation throughout the building, allowing the network to adapt to varying indoor coverage challenges without requiring physical reconfiguration of base stations.
