Types of Broadband

Broadband Flavors

Wired:Digital Subscriber

Lines (DSL)Cable ModemLeased Lines (T1)Fiber Optic CableBroadband Over

Powerline (BPL)

Wireless: Satellite Fixed Wireless Wi-Fi WiMAX

Digital Subscriber Line (DSL)

Uses plain old phone lines (POTS) Voice and data over the same lineSpeed 1.5-8 MbpsRequires location near central phone office or

switch (18,000 feet)Phone lines are everywhere but not all of them

are able to support DSLDirect one-on-one connection; bandwidth is not

shared with neighbors

CPI:-

Cable ModemFaster than DSLUses the same cable television lines that

deliver pictures and sound to your TV setShared connection; speeds can slow down

when many people in the same neighborhood are online

Easy to install

A Typical cable modem setup at customer end :

Broadband Over Powerline (BPL)

Delivered through power linesAlmost 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

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 signalNeed unobstructed view of southern sky

Fiber Optic CableDelivered over fiber optic cablesVery high bandwidthHigh cost to build fiber networkLow maintenance

Wireless BroadbandFast relatively inexpensive deploymentDSL and cable speedsMany varieties

— Point-to-Point— Point-Multipoint— Mesh— Hot zones— Hot spots

Point-to-Point Fixed WirelessUses 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 bandwidthUsually licensedBackbone or transport layerLine of site

Point-to-Multipoint Fixed WirelessBroadband delivery to premiseConsumer or business gradeOne antenna to many sitesLine-of-sightLarge coverage areaLicensed or unlicensed

Mesh Network Wireless Nodes (radios)

Connect to userTransmit to aggregation point

Typically unlicensedFavor urban areas or hot zones

Aggregation Point

Mobile Wi-Fi

Wireless fidelityWi-Fi access points found at cafés, homes,

campuses, businesses.Access is limited to 50-300 feetCoverage limited by location and number of

transmittersRelatively cheap for providers to set-up End-user equipment cheap and easy to

install

Where to Wi-FiHotels, 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 stopsTruck stops RV parks

WiMAXWi-Fi on steroids Can cover a large area – 30 milesStill 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.
