Ethernet over Coax (EoC) is a networking technology that enables the transmission of Ethernet data signals over existing coaxial cable infrastructure. Coaxial cables were historically used for cable television (CATV) and other applications, but EoC repurposes them for high-speed data transmission. EoC provides a cost-effective and efficient way to deliver network connectivity and internet access to buildings or locations where coaxial cabling is already in place.

Here are some key features and characteristics of Ethernet over Coax:

  1. Coaxial Cable Infrastructure: EoC utilizes the existing coaxial cable infrastructure, which may include RG-6, RG-11, or other coaxial cable types. This infrastructure was previously used for CATV, satellite TV, or closed-circuit television (CCTV) systems.
  2. High Bandwidth: EoC services offer high bandwidth options, supporting data rates ranging from several megabits per second (Mbps) to over 1 gigabit per second (Gbps), depending on the technology and equipment used.
  3. Symmetric and Asymmetric Bandwidth: EoC can provide both symmetric (equal upload and download speeds) and asymmetric (faster download speeds than upload speeds) bandwidth options, catering to various applications and customer requirements.
  4. Modulation Techniques: EoC often uses advanced modulation techniques such as orthogonal frequency-division multiplexing (OFDM) to maximize data transmission rates over coaxial cables.
  5. Frequency Bands: EoC devices operate on different frequency bands, allowing them to coexist with existing CATV or cable television services without interference.
  6. Distance Considerations: The maximum achievable bandwidth and performance of EoC are influenced by the quality of the coaxial cable and the distance between the customer’s location and the service provider’s equipment.
  7. Managed Services: EoC services can be offered as managed solutions, including installation, configuration, monitoring, and maintenance by the service provider.
  8. Service-Level Agreements (SLAs): Many EoC services come with SLAs that specify performance guarantees, uptime commitments, and response times to ensure reliable network performance.
  9. Security Features: EoC services may include security features like firewall protection, intrusion detection and prevention, and VPN support to enhance network security.
  10. Business Continuity: EoC can be used as part of a business continuity and disaster recovery strategy, providing redundant internet connectivity options.
  11. Cost-Effective Deployment: EoC is often a cost-effective solution for delivering high-speed internet access to buildings or locations where fiber-optic infrastructure deployment is impractical or costly.
  12. Static IP Addresses: Many EoC services come with static IP addresses, which are useful for hosting websites, remote access, and VPNs.

Ethernet over Coax is particularly suitable for scenarios where there is an existing coaxial cable infrastructure, such as multi-dwelling units (MDUs), apartment complexes, hotels, and commercial buildings. It allows property owners and businesses to leverage their existing cabling to access high-speed internet and Ethernet-based network services without the need for extensive rewiring or infrastructure upgrades.
