    Study Notes

    Broadband Connections

    • Cable System Overview
      • Utilizes coaxial cable to transmit radio frequency (RF) signals.
      • Provides high-speed Internet access, digital cable TV, and residential phone services.
      • Operates on hybrid fiber-coaxial (HFC) networks for fast data transmission.

    Cable Components

    • Essential Equipment for Cable Systems
      • Cable Modem Termination System (CMTS): Located at the cable operator's headend, functions as a router with databases for Internet services to subscribers.
      • Cable Modem (CM): Installed on the subscriber end to enable connectivity.

    Digital Subscriber Line (DSL)

    • DSL Definition

      • Digital Subscriber Line allows high-speed Internet connections via existing copper telephone wires.

    • Types of DSL

      • Asymmetric DSL (ADSL): Higher download speeds than upload speeds.
      • Symmetric DSL (SDSL): Equal download and upload speeds.
      • ADSL service requires local loop lengths less than 3.39 miles (5.46 km) for optimal performance.

    DSL Connections

    • Connection Setup

      • Established between customer premises equipment (CPE) and a DSL access multiplexer (DSLAM) at the Central Office (CO).

    • Key Components

      • Transceiver: Typically a modem that connects a user's computer to the DSL.
      • DSLAM: Aggregates individual DSL connections into a high-capacity link to an Internet Service Provider (ISP).

    • DSL Advantages

      • Unlike cable technology, DSL offers dedicated connections, avoiding shared bandwidth issues.

    Wireless Connection

    • Broadband Wireless Technologies

      • Municipal Wi-Fi: Uses a mesh of interconnected access points for city-wide Internet access.
      • Cellular/Mobile: Utilizes radio waves via cell towers, with speeds improving significantly; LTE Category 10 supports 450 Mb/s download and 100 Mb/s upload.
      • Satellite Internet: Ideal for remote areas without terrestrial Internet; requires antenna aiming toward the equator for effective installation.

    • Market Trends

      • WiMAX has largely been supplanted by LTE for mobile connectivity, whereas cable and DSL dominate fixed access.

    Comparing Broadband Solutions

    • Factors Influencing Broadband Choice
      • Cable: Bandwidth shared among users leading to slower speeds during peak hours.
      • DSL: Bandwidth limited by the distance from the ISP's central office.
      • Fiber-to-the-Home: Requires infrastructure for direct fiber installation at homes.
      • Cellular/Mobile: Coverage can be inconsistent.
      • Wi-Fi Mesh: Often lacks widespread municipal deployment.
      • Satellite: Generally high cost with limited user capacity.
