What is Broadband?
Multiple answers to this question
Characterized by its ability to provide multiple services over a single connection
What is Broadband?
Historically, broadband has been defined as: The opposite of narrowband Having a bandwidth greater than a voice grade line of
3 kilohertz (kHz) Facilitating a data transfer rate greater than 64
kilobits per second (Kbps) Facilitating a transfer rate equal to or greater than
768 Kbps downstream and 200 Kbps upstream (NTIA definition)
Current FCC Definition is at least 4 Mbps (megabits per second) downstream and 1 Mbps upstream

What is Broadband?
Historically, broadband has been defined, cont’d: Cable television, sometimes referred to as a
“classic” broadband system
Anything referred to as “broadband” by advertisers

What is Broadband?
How is broadband different from “not broadband”? Provides higher-speed of data transmission
Provides access to the highest quality Internet services
Broadband is “always on”
Less delay – enables high bandwidth, high capacity, “real-time” services

DOCSIS
Data Over Cable Service Interface Specifications
Current DOCSIS 3.0 systems offer 100+ Mbps downstream and 20+ Mbps upstream to customers
DOCSIS 3.1 demonstrated speeds of 6 Gbps downstream in a lab setting using 750 MHz of bandwidth (85% - 100% of total bandwidth available on most active cable systems today)

Broadband’s Impact on Cable Television
Switched Digital Video (SDV)/Switched Digital Broadcast (SDB) Frequently viewed channels broadcast to all
(system-wide delivery)
Other channels are individually selectable (multi-use bandwidth)
Interactive Television (ITV) Two-way services allowing application developers
access to subscribers through the cable platform
Switched Digital Video/ Switched Digital Broadcast
CBG Communications, Inc.
Interactive Television
Interactive Television (ITV) is one way that service delivery is moving to attract the younger generation that desires and seeks out such services.
The cable industry is focusing on adding interactive elements, and consequently more on demand features, to traditional TV programming
It also allows the industry to promote convergence across TV, internet, digital phone, mobile and other device platforms, which are all platforms that the industry is involved in now

Broadband Is:
Everywhere (or rather, needs to be)
Essential
Connecting us to the Future!
