1 LIGHTS! Broadband Basics Presented by: Tom Robinson, President 73 Chestnut Rd, Suite 301 Paoli, PA Phone (610) NATOA ANNUAL CONFERENCE SEPTEMBER 17, ORLANDO, FL

2 What is Broadband? Multiple answers to this question Characterized by its ability to provide multiple services over a single connection

3 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

4 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

7 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

8 Broadband Speed Comparisons

10 Broadband Technology Elements Wireline Fiber optic infrastructure Also copper such as twisted pair (phone lines) and coax (cable TV)

11 Wireline Connectors

12 Broadband Technology Elements Wireline, cont d Advanced transport methodologies Such as Gigabit Ethernet (1 billion bits per second) Switched services Information appliances In the house and portable

13 Broadband Technology Elements Wireline, cont d NIUs, NIDs, home gateways, etc. At the side of the building

14 Broadband Technology Elements Wireless Wireless antennas and towers

15

16 Broadband Technology Elements Wireless, cont d Wireless Fidelity (Wi-Fi) a & g data transfer rates up to 54 Mbps b data transfer rates up to 11 Mbps n throughputs in excess of 150 Mbps Cellular Broadband 3G (3 rd Generation) Speeds of up to 4 Mbps

17 Broadband Technology Elements Wireless, cont d WiMAX Significantly greater coverage areas Used for backhaul initially As WiMAX evolves, it will migrate further into the network e 4G (4 th Generation) Speeds of up to 30 Mbps+ LTE (Long Term Evolution)

18 Wireless Technology Options Best effort services 100% of networks throughput is shared by all users Every user gets equal priority on and access to the network Priority-based services VoIP Emergency communications IP video

19 Broadband Networks LAN Local Area Network In home, in office, in building Metropolitan Area Network (MAN) Wide Area Network (WAN) Institutional Networks (I-Nets) Community Broadband Networks

20 Residential HFC Residential Downtown Plant Cable System Headend Network of Networks Residential HFC Plant HFC Plant Library Schoo Fire Station Residential City Backbone and Cable Backbone Residential Residential Residential

21 Broadband Services Services Provided Primarily to Businesses Transparent LAN, Ethernet private line services 10 Mbps 100 Mbps 1 Gbps T-1 (1.54 Mbps) Dark fiber lease

22 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.])

25 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)

26 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)

27

28 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 (multiuse bandwidth) Interactive Television (ITV) Two-way services allowing application developers access to subscribers through the cable platform

29 Switched Digital Video/ Switched Digital Broadcast

30 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

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

33 Thank you!
