Distributed Antenna Switch Aggregating Downlink Data Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distributed Antenna Systems (DAS) face challenges in efficiently aggregating and routing serialized data streams across multiple network interfaces and remote antenna units, leading to complexities in signal distribution and management within closed environments.
Innovation Solution
A distributed antenna switch is designed to aggregate downlink serialized data streams from multiple network interfaces into a single aggregate stream, which is then communicated to remote antenna units, while also receiving and splitting uplink streams, using a combination of digital communication links and serial link interface units to manage data routing and conversion efficiently.

Engineering Contradiction Analysis
1Reliability
If distributed antenna systems use multiple network interfaces to receive serialized data streams, then signal coverage and reliability are improved, but device complexity and routing management become worse
Solution Approach 1:
The patent combines multiple downlink serialized data streams from different network interfaces into a single aggregate downlink serialized data stream. The distributed antenna switch receives multiple input streams and merges them into one aggregated stream that is then transmitted to remote antenna units, simplifying the routing architecture while maintaining support for multiple network interfaces
Solution Approach 2:
The distributed antenna switch is designed to handle multiple types of data streams from different network interfaces through a universal aggregation mechanism. The same switch infrastructure processes and aggregates streams from various sources, providing multi-functional capability without requiring separate routing paths for each interface
2Productivity
If distributed antenna systems aggregate multiple serialized data streams into a single stream, then routing efficiency is improved, but data stream management complexity increases
Solution Approach 1:
The aggregate downlink serialized data stream is segmented and distributed to different remote antenna units based on their specific requirements. Each remote antenna unit receives the aggregated stream and can extract or process the relevant portions it needs, allowing efficient routing while maintaining manageable data stream handling at each endpoint
Solution Approach 2:
The distributed antenna switch acts as an intermediary device that manages the aggregation and distribution of serialized data streams. It mediates between multiple network interfaces and remote antenna units, handling the complexity of stream management centrally while presenting simplified interfaces to both sides

AI summary
A distributed antenna switch includes a plurality of first interfaces, each of the plurality of first interfaces configured to receive a downlink serialized data stream from a different network interface across a different first digital communication link; at least one second interface, the at least one second interface configured to communicate an aggregate downlink serialized data stream to a remote antenna unit over a second digital communication link; and wherein the distributed antenna switch is configured to aggregate the plurality of downlink serialized data streams from the different network interfaces into the aggregate downlink serialized data stream.
