What is Broadband? Multiple answers to this question Characterized by its ability to provide multiple services over a single connection CBG Communications, Inc.
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 CBG Communications, Inc.
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 CBG Communications, Inc.

Broadband Services Services for business, SOHO business, and the residential community Digital Subscriber Line (xDSL) Cable modem services (HSI) Integrated wireless services (cellular voice/wireless Internet access for integrated voice/data devices [smartphones, tablets, etc.]) CBG Communications, Inc.
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) CBG Communications, Inc.
Broadband Impact on Cable Television Transport to the headend Digital, optical, IP-based Uncompressed digital Delivery to subscribers Compression ratio or encoding rate utilized QAM (Quadrature Amplitude Modulation)-based IPTV (Internet Protocol Television) CBG Communications, Inc.
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 CBG Communications, Inc.
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 CBG Communications, Inc.
Broadband Is: Everywhere (or rather, needs to be) Essential Connecting us to the Future! CBG Communications, Inc.
