Solution Overview
Problem
The existing methods for adjusting the positions of wireless transceivers in cellular access points to establish and maintain wireless backhaul connections are labor-intensive and require substantial manpower, as they rely on manual adjustments by field engineers.
Innovation Solution
A system where cellular access points, including macrocell and small cell systems, can request and receive location data or positioning instructions from a telecommunication network server, allowing them to autonomously adjust their wireless transceivers to establish and maintain wireless backhaul connections using techniques like beamforming and RF sweeps, reducing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment of wireless transceivers by field engineers is used, then wireless backhaul connections can be established, but substantial manpower investment is required
Solution Approach 1:
The wireless transceivers automatically perform RF sweeps and beamforming operations to establish and maintain wireless backhaul connections without requiring manual intervention by field engineers. The system self-configures by autonomously scanning for available connections and adjusting antenna positions based on signal quality measurements.
Solution Approach 2:
The system performs preliminary RF sweeps and signal quality assessments before finalizing wireless backhaul connections. By pre-evaluating potential connection targets and preparing beamforming parameters in advance, the system reduces the need for iterative manual adjustments and accelerates deployment.
2Reliability
If field engineers manually adjust wireless transceiver positions, then connections can be established, but the process is labor-intensive and time-consuming
Solution Approach 1:
The wireless transceivers perform periodic RF sweeps and signal quality measurements to automatically detect and establish optimal backhaul connections. This periodic automated scanning replaces continuous manual adjustment, significantly reducing deployment time while maintaining connection reliability.
Solution Approach 2:
The patent replaces the mechanical manual adjustment process with an automated electronic control system that uses RF signal measurements and algorithmic decision-making to position and configure wireless transceivers. This substitution eliminates the time-consuming manual intervention while achieving the same connection establishment goal.
3Ease of operation
If automated systems are implemented, then manpower requirements are reduced, but system complexity increases
Solution Approach 1:
The wireless transceiver system integrates multiple functions including RF sweeping, signal quality measurement, beamforming, and automatic position adjustment into a single unified platform. This multi-functionality reduces the need for separate specialized equipment and simplifies the overall system architecture despite the advanced automation capabilities.
Solution Approach 2:
The patent introduces a centralized controller or management system that coordinates the automated operations of multiple wireless transceivers. This intermediary manages the complexity by providing high-level coordination and abstraction, allowing individual transceivers to operate autonomously while maintaining system-wide optimization through centralized oversight.

AI summary
Described herein are techniques preparing a wireless backhaul among cellular access points. The cellular access points may obtain either (i) locations of themselves and other devices or (ii) instructions for adjusting position of wireless transceivers of the cellular access points. Based at least in part on the locations or instructions, the cellular access points may adjust positions of the wireless transceivers and initiate wireless connections via the wireless transceivers. The cellular access points may receive the locations or instructions from a server of the telecommunication network, which may determine pairs of the cellular access points based at least in part on the locations of the cellular access points.
