Engineering Contradiction Analysis
1Quantity of substance
If fiber deployment is used to provide high-capacity transport, then bandwidth and capacity are improved, but deployment cost and complexity increase significantly
Solution Approach 1:
The patent replaces physical fiber optic infrastructure (mechanical system) with wireless millimeter wave communication systems. This substitution eliminates the need for expensive fiber laying while providing comparable high-capacity transport through advanced wireless technologies operating in 28 GHz and 38 GHz bands
Solution Approach 2:
The patent changes the operational parameters by utilizing millimeter wave frequency bands (28 GHz, 38 GHz) with bandwidths of 500 MHz to 2 GHz, enabling high-capacity wireless transport that can replace fiber in cost-sensitive deployments while maintaining adequate performance
2Ease of manufacture
If wireless backhaul is used to reduce deployment cost, then ease of deployment is improved, but latency and connection reliability worsen
Solution Approach 1:
The patent implements dynamic beamforming and adaptive modulation techniques that adjust transmission parameters in real-time to optimize performance. The system dynamically manages multi-hop connections and performs continuous link quality assessment to maintain low latency despite wireless medium variations
Solution Approach 2:
The patent performs preliminary beam alignment and connection establishment before actual data transmission begins. The system pre-configures multi-hop paths and performs link quality assessments in advance to minimize latency during active communication
3Adaptability or versatility
If traditional routing protocols are used in wireless backhaul, then compatibility is improved, but network efficiency and adaptability to topology changes worsen
Solution Approach 1:
The patent segments the routing function into hierarchical levels: traditional protocols handle basic connectivity while an overlay optimization layer manages path selection and topology adaptation. This segmentation maintains compatibility with existing infrastructure while enabling advanced efficiency improvements through software-defined networking principles

AI summary
Systems and methods are described for providing wireless backhaul transport. One element of the system is a highly integrated radio transceiver, including an integrated antenna. The radio transceiver may operate in the millimeter wave range (between 30 GHz and 300 GHz), and due to the small wavelengths, it is possible to integrate the antenna, which may typically compromise a number of antenna elements, with the radio transceiver in a single integrated circuit (IC) package, commonly referred to as a system-in-package (SiP) and/or antenna-in-package (AiP) format. The system supports multi-hop point-to-multipoint or multi-hop mesh networking topologies. Low level MAC routing tables are built and maintained to enable efficient packet and frame forwarding.
