Solution Overview

Problem

The conventional method of installing access points (APs) freely by subscribers makes it difficult to optimize the configuration of the entire mobile communication network, especially in the 6G era where higher frequency and wider bandwidth radio communications are required, leading to issues with efficiency, rapidity, effective utilization of frequency resources, fault tolerance, and optimization.

Innovation Solution

A communication device (NCAP) that can be installed by subscribers but controlled by network operators, providing functions similar to a radio base station, and configured to optimize the network architecture through self-organizing networks (SON) and other frameworks, ensuring efficient, rapid, and fault-tolerant network deployment.
