  • CABLE MODEM Faster than DSL Uses the same cable television lines that deliver pictures and sound to your TV set Shared connection speeds can slow down when many people in the same neighborhood are online Easy to install
  • Slide 5
  • BROADBAND OVER POWERLINE (BPL) Delivered through power lines Almost all homes and businesses are connected to the power grid Still in early stages of development Potential interference with radio signals Speeds similar to DSL and cable
  • Slide 6
  • SATELLITE Available most places, including hard-to-reach rural areas Slower than cable or DSL. WildBlue download speeds up to 1.5 Mbps and upload speeds up to 256 Kbps. Trees and heavy rain affects signal Need unobstructed view of southern sky Graphic from WildBlue.com

  • Slide 13
  • MOBILE WI-FI Wireless fidelity Wi-Fi access points found at cafs, homes, campuses, businesses. Access is limited to 50-300 feet Coverage limited by location and number of transmitters Relatively cheap for providers to set-up End-user equipment cheap and easy to install
  • Slide 14
  • WHERE TO FIND WI-FI Hotels, motels, inns, and resorts Airports Public libraries Cybercafes and fast food restaurants Courthouses City parks like NYC's Central Park Public recreation areas and rest stops Truck stops RV parks
