Active Antenna TRX Module Segmentation for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional active antenna architectures face challenges in reducing power consumption without affecting the radiation pattern and coverage, leading to increased dropped and blocked calls during TRX module switching.
Innovation Solution
An energy-efficient active antenna architecture with master and slave TRX modules, where master modules are always active and radiate minimum output power, and slave modules are switched on/off based on traffic load, maintaining the radiation pattern and coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If TRX modules are switched off to save power, then power consumption is reduced, but the radiation pattern and coverage are affected
Solution Approach 1:
The antenna array is segmented into multiple independently controllable TRX modules, each capable of being switched on or off individually. This segmentation allows selective deactivation of certain modules to reduce power consumption while maintaining others to preserve coverage and radiation pattern characteristics.
Solution Approach 2:
The system dynamically adjusts the operational state of TRX modules based on traffic load conditions. During low traffic periods, fewer modules are activated to save energy; during high traffic periods, more modules are activated to maintain service quality. This dynamic adaptation resolves the contradiction between power savings and coverage maintenance.
2Use of energy by stationary object
If TRX modules are switched off to save power, then operational expenses are reduced, but network performance indicators deteriorate
Solution Approach 1:
The system changes the operational parameters of TRX modules based on network conditions. By adjusting which modules are active and at what power levels, the system optimizes the balance between operational expenses and network performance indicators such as dropped calls and blocked calls.
3Productivity
If maximum output power is used, then service capacity is maximized, but energy efficiency deteriorates
Solution Approach 1:
Instead of always operating at maximum capacity, the system applies partial action by activating only the necessary number of TRX modules based on actual traffic demand. This avoids the energy waste of operating at maximum power when full capacity is not required, thereby improving energy efficiency while maintaining adequate service capacity.
