Solution Overview

Problem

The challenge of deploying cellular networks with high capacity and density in locations that are not pre-wired, particularly in urban environments, is exacerbated by the high cost and logistical challenges of traditional fiber-based cabling, which limits installation flexibility and increases deployment time and cost.

Innovation Solution

The use of 60 GHz wireless communication systems, leveraging integrated circuits and advanced System-on-Chip (SoC) technology, to establish high-throughput, low-latency wireless fronthaul connections between radio and distributed units, eliminating the need for extensive fiber installations and enabling flexible, scalable, and cost-effective network deployment.

Solution Approach 1:

The patent replaces the mechanical fiber-optic cabling system with a wireless communication system operating at 60 GHz. Instead of physically installing fiber cables through urban environments, the system uses wireless signals to establish fronthaul connections between radio units and distributed units, eliminating the need for trenching, cable laying, and physical infrastructure installation while maintaining high data transmission capacity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the transmission medium parameter from physical fiber-optic cables to electromagnetic waves in the 60 GHz frequency band. This parameter change enables rapid deployment without physical installation while achieving the required network capacity through high-frequency wireless communication with sufficient bandwidth for 5G fronthaul requirements

Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent segments the data transmission stream into multiple parallel channels using MIMO technology with multiple transmit and receive antennas. Each antenna element or antenna pair operates as an independent spatial channel, allowing the system to achieve aggregate bandwidth equivalent to or exceeding fiber-optic connections by combining the capacity of multiple wireless channels

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent exploits the spatial dimension by implementing MIMO (Multiple-Input Multiple-Output) communication with multiple antennas. This adds a spatial dimension to the wireless channel, creating parallel transmission paths through space that multiply the effective bandwidth and capacity of the wireless fronthaul connection

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
