1. Bandwidth for the Home Chapter 15 The Management of Telecommunications Houston H. Carr and Charles A. Snyder

2. 2 Chapter 15 Introduction Digital bandwidth to the home has evolved greatly over the past few years. Until recently, connectivity from a home meant a modem over POTS lines.

3. 3 Chapter 15 Options for the Home Bandwidth Media WiredWireless Low High

4. 4 Chapter 15 Video-on-demand Video-on-demand gives the user choice, based on storage of movies and other programs at the source. Near video-on-demand gives user access to a large library of films, but requires human intervention.

7. 7 Chapter 15 Small office/home office (SOHO) More people are working out of their homes, or small satellite offices due to  The size and nature of their businesses  The need for special accommodations. People who work in SOHO realize the value of fixed and mobile connectivity.

8. 8 Chapter 15 HFC and FTTC for the Home Fiber-based broadband alternatives for the home  Hybrid fiber coax (HFC)  Fiber to the curb (FTTC)

9. 9 Chapter 15 Wireless considerations Wireless is a strong competitor to coaxial cable, UTP, and fiber media for three reasons  The cost of the last miles is less  Installation can be much quicker and less expensive, and  The end node can often move without special considerations.

10. 10 Chapter 15 Wireless considerations Cellular to the home Multipoint Multichannel Distribution Systems (MMDS) Data from satellite Bluetooth and IEEE 802.11a/b

11. 11 Chapter 15 Bluetooth Bluetooth is an attempt to allow any wireless device to connect to any other wireless device.  Designed for short distances  Bandwidth of about 700 Kbps

12. 12 Chapter 15 IEEE 802.11a/b A second wireless method of connectivity. IEEE 802.11b has a bit longer range and much higher bandwidth (11 Mbps). IEEE 802.11a parameters call for a bandwidth of 51 Mbps, offering a path for video conferencing and other high-speed needs.

13. 13 Chapter 15 Internet access Applications and issues include  Web-based learning  Copyright Infringement  Video compact disk movies (V-CD)  Video porn  Online banking and Bill paying  Online auctions  Audio, still pictures, and video download  Interactive video chat  Web-based gaming
