Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If retransmission of digital audio data is implemented, then reliability of audio transmission is improved, but latency increases
Solution Approach 1:
The system pre-positions multiple Remote Digital Antennas at different spatial locations before transmission occurs. These RDAs are ready to receive and process signals simultaneously, eliminating the need for retransmission delays by having redundant reception paths prepared in advance.
Solution Approach 2:
The invention creates multiple copies of the digital audio signal reception capability through redundant RDAs. Each RDA independently receives and processes the same transmitted signal, providing backup reception paths that eliminate the need for retransmission and associated latency.
2Reliability
If spatial diversity with multiple antennas is used, then reliability of signal reception is improved, but device complexity increases
Solution Approach 1:
The system divides the reception function into separate Remote Digital Antennas distributed at different locations. Each RDA is a simple, identical unit that performs only signal reception and initial processing, while the complex coordination and signal combination functions are centralized in the main receiver, reducing individual component complexity.
Solution Approach 2:
Each Remote Digital Antenna is designed as a universal, multi-functional unit capable of receiving signals across multiple frequencies and formats. This standardization allows the same simple RDA design to be deployed repeatedly without increasing individual unit complexity, while the system as a whole gains enhanced reliability.

AI summary
Embodiments relate to a system and a method for a redundant real-time wireless receiver network. A Remote Digital Antenna Digital Receiver (“RDADR”) is coupled to multiple Remote Digital Antenna (“RDAs”). The RDADR and the multiple RDAs are coupled via a digital bus. The multiple RDAs attempt to receive one or more digital signals from a transmitter. If the one or more digital signals are received without an error by one of the multiple RDAs, the RDA that received the one or more error-free digital signals sends the digital signals to the RDADR using the digital bus. The redundant real-time wireless receiver network provides a reliable and fault tolerant system to deliver digital audio signals in real-time.
