Ethernet over Coax (EoC) is a networking technology that enables high-speed data transmission over existing coaxial cable infrastructure. It repurposes the same coaxial cables that were traditionally used for cable television (CATV) and other video-related applications to deliver Ethernet-based data services. EoC is primarily used in scenarios where organizations want to upgrade their network connectivity without having to replace the existing coaxial cabling, making it a cost-effective solution.

Key Features of Ethernet over Coax (EoC):

  1. Utilizes Existing Coaxial Cabling: EoC leverages the installed base of coaxial cables, which may include RG-6 or RG-59 cables used for cable television, to transmit Ethernet data.
  2. High-Speed Connectivity: EoC offers high-speed internet and network connectivity, with typical bandwidths ranging from several Mbps to over 100 Mbps, depending on the quality and length of the coaxial cables.
  3. Symmetrical or Asymmetrical Bandwidth: EoC can provide symmetrical (equal upload and download speeds) or asymmetrical bandwidth, depending on the service offering and customer requirements.
  4. Scalability: EoC services are scalable, allowing organizations to increase or decrease bandwidth as needed to accommodate changes in data traffic.
  5. Compatibility: EoC can coexist with existing CATV and video distribution systems, making it suitable for hotels, multi-dwelling units (MDUs), and other facilities where both data and video services are needed.
  6. Quality of Service (QoS): EoC can support QoS features to prioritize network traffic based on application requirements, ensuring that critical applications receive the necessary resources.

Use Cases for Ethernet over Coax (EoC):

  1. Hospitality Industry: Hotels and resorts often use EoC to provide high-speed internet access to guests over existing coaxial cabling in guest rooms.
  2. Multi-Dwelling Units (MDUs): EoC is suitable for connecting apartments, condominiums, and other MDUs to high-speed internet services without rewiring the building.
  3. Education: Educational institutions can use EoC to upgrade network connectivity in older buildings where coaxial cables are already in place.
  4. Business Connectivity: Small and medium-sized businesses may adopt EoC to connect branch offices or remote locations using existing coaxial infrastructure.
  5. Backup Connectivity: EoC can serve as a backup connectivity option in case of primary connection failures, providing network redundancy and continuity.
  6. Digital Signage: EoC can be used to connect digital signage displays, information kiosks, and video surveillance cameras.
  7. CCTV Surveillance: EoC is suitable for transmitting video feeds from security cameras over long distances.
  8. Event Venues: Temporary network connectivity at event venues can be established using EoC, especially when setting up networks for conferences, trade shows, or outdoor events.

In summary, Ethernet over Coax (EoC) is a networking technology that repurposes existing coaxial cable infrastructure to deliver high-speed internet and Ethernet connectivity. It is a cost-effective solution for organizations and facilities where upgrading the network infrastructure would be impractical or expensive. EoC can provide reliable connectivity for various applications, including hospitality, MDUs, education, and business environments.
