Cost-Effective Wired Communication Technology Using Existing Wire

In the development of communication networks, various challenges emerge in achieving wireless signal coverage in certain areas, while the cost of deploying traditional wired Ethernet remains prohibitive in specific locations. Industries accustomed to slower wired communications now seek high-speed alternatives to facilitate IoT integration and enhance operational efficiency, yet they are hesitant to undertake extensive rewiring efforts.

Building networks across diverse settings, including buildings, condominiums, and factories, often encounters significant cost hurdles. This is primarily due to the need for multiple Wi-Fi repeaters to cover areas with poor signal reach, as well as the requirement for numerous network switches and construction work involving cable installation under floors and above ceilings.

A solution lies in technology that facilitates data communication over existing wires within facilities, such as flat cables, twisted pair wires, coaxial cables, and power lines. The effective communication speed varies from several Mbps to several tens of Mbps, depending on the type of cable and the wiring environment. Moreover, this technology seamlessly integrates with Wi-Fi, Ethernet, and other existing infrastructures, providing a cost-effective approach to network construction. By leveraging these technologies, it becomes feasible to establish society's network infrastructure at a reduced cost, particularly in challenging environments such as concrete structures, underground areas, tunnels, and spaces with metal walls.
