Distributed Remote Base Station System Latency Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wireless communication systems face inefficiencies due to the need for signals received by distributed antennas to be sent back to a centralized base station for processing, leading to increased latencies and unacceptable disruptions in service, as each remote antenna shares capacity with every other antenna connected to the centralized base station.
Innovation Solution
A distributed base station system with a modular wireless platform that includes reconfigurable host and remote units, each equipped with a serial radio frequency (SeRF) communicator and digital to analog radio frequency (DART) modules, allowing for flexible adaptation to different data transport mechanisms, frequency bands, and communication technologies, enabling decentralized processing of wireless signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signals are sent back to centralized base station for processing, then centralized control is achieved, but latency increases
Solution Approach 1:
The patent segments the base station functionality by distributing remote antenna units (RAUs) across multiple locations, each capable of local signal processing. This segmentation allows signals to be processed at the nearest RAU rather than being transmitted back to a centralized base station, reducing latency while maintaining system-wide coordination through the controller unit.
2Productivity
If remote antennas share capacity with every other antenna, then resource utilization is optimized, but service disruption occurs
Solution Approach 1:
The system segments the network into multiple independent remote antenna units, each with dedicated processing capabilities. This segmentation allows each RAU to handle local traffic independently, preventing service disruptions caused by capacity sharing conflicts while still enabling resource optimization through the controller unit that coordinates data routing between RAUs.
Solution Approach 2:
The controller unit acts as an intermediary between remote antenna units, managing data routing and resource allocation. It receives data from transmitting mobile devices, determines the optimal destination RAU, and routes the data accordingly, thereby optimizing resource utilization across the network while ensuring service continuity through intelligent traffic management.
3Area of stationary object
If distributed antennas are used to expand range, then coverage area increases, but unnecessary signal transmission occurs
Solution Approach 1:
The controller unit serves as an intermediary that intelligently routes data between remote antenna units based on the destination mobile device's location. When a signal is received at one RAU intended for a mobile device associated with another RAU, the controller unit directs the signal locally rather than transmitting it back through the centralized base station infrastructure, eliminating unnecessary transmissions and energy waste while maintaining expanded coverage.
