1. NEW MEDIA AND COMMUNICATION TECHNOLOGIES
New Tech: Assumptions to be tested about “Broadband”
Platforms for economic and social change
Role in user-to-user collaboration
Different networks/devices have different advantages/limitations
Dysfunctional as well as beneficial effects accompany technological change

2. Key concepts
Access to technology not only shapes what you can now do; it now shapes what you can dream about doing
Information and communications infrastructure is one of the important benchmarks in determining your and your community’s competitiveness and level of prosperity
Network-connected devices and apps are doing more, faster and more economically for you/for your business/for your community than ever before
The networking of digital devices and apps allows local communities and local businesses to transform themselves by reaching out to potential markets and collaborators almost anywhere on earth (or space)

3. BROADBAND MEDIA AND COMMUNICATIONS INFRASTRUCTURE
BROADBAND TELEPHONY
BROADBAND CABLE
BROADBAND WIRELESS
BROADBAND SATELLITE
BROADBAND BROADCASTING
BROADBAND INTERNET

4. BROADBAND TELEPHONY
TELEGRAPHY: FAST DISTANT COMMUNICATION STARTED WITH ELECTRICAL CURRENT VIA COPPER WIRE Advantages? Limitations? TELEPHONY: SIMULTANEOUS (2-WAY) VOICE COMMUNICATION VIA COPPER WIRE BB-TELEPHONY: ANALOG TO DIGITAL, IP-NETWORKS, xDSL COPPER LINES, FIBER OPTIC LINES ROLE OF BELL LABS: MICROELECTRONICS, DIGITAL SYSTEMS; SOLFTWARE; PHOTONICS

5. DATA OVER TELEPHONE LINES
DIAL-UP MODEMS

6. Digital Subscriber Line (DSL)
Digital pipeline into customer premises
Convert regular “twisted pair” copper telephone line into high-capacity telecommunication line
Voice-grade modem vs. DSL
14.4Kbps – 56Kbps vs. 1.5Mbps – several Mbps

7. FIBER OPTICS
LIGHT (LED AND LASER)

8. Fiber Optics
FIBER OPTICS
FLEXIBLE GLASS CABLES

9. Technological Factors
Flexible glass (or plastic) fibers
Sound/video/data converted to electrical signal, which is converted to light pulses
Light travels faster
Less attenuation
Optical fibers carry more information
Not affected by electrical or radio interference of lightening.

10. Economic Factors High capacity/high data rate
Accuracy (low error bit rate)
High reliability (low maintenance)
Data security
Fewer amplifiers/repeaters
Smaller size, lesser weight
Sand (silicon) vs. copper
Global market: Internet growth,
VoIP (IP telephony)

11. Applications PPV VOD Internet E-commerce/E-gov/E-edu/E-health
IP-Telephony (VoIP)
DTV/HDTV
Digital Video Recorders/Burners
Gaming
