1 Broadband Networks

2 What is Broadband? Transmission capacity faster than 1.5 Mb/s (International standard) Transmission speed of more than 200 Kb/s

3 Why Broadband? Greater multimedia based entertainment and information programming Improved capability for telework Better potential for e-government Increased possibilities for stuff we don’t even know about yet

4 Growth Up 27% in 2003 Dial-up connections growth = 0%

5 Broadband Technologies Cable modem DSL Fixed Wireless Broadband Wireless Local Area Networks Fiber to the Home Satellite Broadband Broadband over power lines

6 Current State 61% of users still use dial-up to access the Internet 54% of Broadband users access the Internet via cable modem 42% use DSL 3% use wireless or satellite

7 Broadband Use News41% Research for Work30% Stream Multimedia21% Download Music13%

8 How Fast? Cable Modem: 1.5 mbps downstream and 128 kbps upstream – Adelphia – 16mbps – Cablevision – 100mbps DSL: same as cable modem Wireless: 128 kbps to 10 mbps over 50 km Satellite: 500 mbps downstream and 256 kbps upstream Power Lines: 256 kbps

9 Which will Dominate? Cable does now DSL will later Voice over IP will be the main revenue source
