Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face limitations in extending coverage, maintaining low latency, and ensuring ultra-reliable connectivity due to bandwidth constraints, interference, and network architecture inconsistencies, particularly in Wi-Fi® and mesh networks, which are exacerbated by the introduction of additional access points for range extension.
Innovation Solution
A wireless communication system utilizing hybrid analog-digital repeater devices managed by a central cloud server that dynamically forms a wireless backhaul network, combining analog signal relaying for low latency with digital processing for intelligence, enabling near-zero latency and high throughput communication through a hybrid architecture that optimizes beam parameters and network topology based on telemetry data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If additional wireless access points are introduced to extend coverage, then coverage area is improved, but latency increases and network complexity increases
Solution Approach 1:
The patent replaces traditional digital Wi-Fi signal relaying with analog radio frequency signal relaying. Hybrid repeater devices receive RF signals from access points and retransmit them as analog RF signals, bypassing the digital processing delays inherent in conventional Wi-Fi mesh networks. This substitution of digital signal processing with analog signal transmission reduces latency while extending coverage area.
Solution Approach 2:
The patent introduces hybrid repeater devices as intermediary components between access points and end devices. These repeaters act as mediators that receive signals from access points and forward them to end devices, enabling coverage extension without requiring end devices to directly connect to distant access points, thereby reducing the number of hops and latency.
2Area of stationary object
If additional wireless access points are introduced to extend coverage, then coverage area is improved, but network complexity increases
Solution Approach 1:
The patent introduces a central cloud server as an intermediary that manages and coordinates the wireless network. The cloud server receives telemetry data from hybrid repeaters and access points, performs centralized processing, and sends control instructions back to network devices. This centralized management simplifies the overall network architecture by reducing the need for complex distributed protocols and peer-to-peer coordination among multiple access points.
Solution Approach 2:
The patent replaces complex digital signal processing and routing decisions at each network device with centralized cloud-based management. Instead of each access point and repeater independently making routing and configuration decisions, the cloud server performs these functions centrally, reducing the computational complexity and processing requirements at individual network devices.
3Adaptability or versatility
If conventional Wi-Fi protocols are used for data transmission, then compatibility is improved, but data transmission speed is limited
Solution Approach 1:
The patent segments the communication function into two distinct parts: control plane communication uses conventional Wi-Fi protocols for compatibility, while data plane transmission uses high-speed analog RF signaling for speed. This segmentation allows the system to maintain protocol compatibility for management and control functions while achieving high data transmission speeds through analog signal relaying in the data path.

AI summary
A wireless communication system including a central cloud server that obtains a first type of telemetry information from hybrid analog-digital repeater devices and a second type of telemetry information from a master wireless access point device and one or more service wireless access point devices. The central cloud server determines intra-node RF beam parameters and inter-node RF beam parameters for each of the hybrid analog-digital repeater devices, controls the hybrid analog-digital repeater devices to dynamically form a wireless backhaul network among the master wireless access point device, the hybrid analog-digital repeater devices, and the one or more service wireless access point devices, and controls the hybrid analog-digital repeater devices to establish one or more analog data propagation paths in the wireless backhaul network in intermediate frequencies, and establish a digital backchannel in the wireless backhaul network via a wireless local area network (WLAN) frequency less than the intermediate frequencies.
