  1. Types of Broadband

  2. Wired: Digital Subscriber Lines (DSL) Cable Modem Leased Lines (T1) Fiber Optic Cable Broadband Over Powerline (BPL) Wireless: Satellite Fixed Wireless Wi-Fi WiMAX Broadband Flavors

  3. Digital Subscriber Line (DSL) • Uses plain old phone lines (POTS) • Voice and data over the same line • Speed 1.5-8 Mbps • Requires location near central phone office or switch (18,000 feet) • Phone lines are everywhere but not all of them are able to support DSL • Direct one-on-one connection; bandwidth is not shared with neighbors

  4. 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

  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 ham radio signals • Speeds similar to DSL and cable

  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 256Kbps. • Trees and heavy rain affects signal • Need unobstructed view of southern sky Graphic from WildBlue.com

  7. Fiber Optic Cable • Delivered over fiber optic cables • Very high bandwidth • High cost to build fiber network • Low maintenance

  8. Wireless Broadband • Fast relatively inexpensive deployment • DSL and cable speeds • Many varieties • Point-to-Point • Point-Multipoint • Mesh • Hot zones • Hot spots

  9. Point-to-Point Fixed Wireless • Uses part of the radio spectrum to send and receive signals. Typically made up of on-the-ground antenna-to-antenna systems. • Requires indoor or outdoor antenna • Coverage about 5 miles transmitter or access point • High bandwidth • Usually licensed • Backbone or transport layer • Line of site

  11. Point-to-Multipoint Fixed Wireless • Broadband delivery to premise • Consumer or business grade • One antenna to many sites • Line-of-sight • Large coverage area • Licensed or unlicensed

  12. Mesh Network Wireless • Nodes (radios) • Connect to user • Transmit to aggregation point • Typically unlicensed • Favor urban areas or hot zones Aggregation Point

  13. Mobile Wi-Fi • Wireless fidelity • Wi-Fi access points found at cafés, 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

  14. Where to 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

  15. WiMAX • Wi-Fi on steroids • Can cover a large area – 30 miles • Still in early stages of development • Can support ultra-broadband - a really big pipe with lots of bandwidth and speed. Just what you would need to run your own real-time online video channel.

  16. How Much Broadband Costs Depends on… • How fast you want to go • Residential or business use • Pricing of the provider
