A last mile example (design b/w = 3kHz)
Future<br />
<strong>Wireless</strong><br />
<strong>Broadband</strong><br />
(10-20 years)<br />
Project Scope<br />
<strong>to</strong> home<br />
<strong>to</strong> mobile
Future requirements versus baseline<br />
HD displays and services will drive future home requirements<br />
Applications unknown; use HDTV on demand as proxy<br />
- HDTV needs 10-20Mb/s constant streaming (see later)<br />
<strong>Last</strong> <strong>Mile</strong> technology HD Services ?<br />
Now ADSL + WiFi baseline No*<br />
Future? TBD… Yes<br />
*But don’t we have 8Mb/s ADSL now … ?
Contention, contention, contention<br />

50:1 contention reduces 8Mb/s ADSL <strong>to</strong> only 160kb/s<br />
Present services and future needs are ‘chalk and cheese’
The need for speed<br />
Quality increases demanded by users will counter codec gains<br />
