Outline

• The Big Picture

• What is “Web 2.0”?

• What’s next? “TV 2.0”?

• What network infrastructure will it take to support it?

Slide 4

What is “Web 2.0”?

• “Parsumer”: “harnessing the collective intelligence”– Databases and Metcalf’s Law– Blogging– P2P

• Rich user experiences– AJAX

• Loosely coupled systems– Reuse and reassembly

• Mashups– Continuous software releases (An ASP model)

• Real-time monitoring of user behaviour– Many devices involved– Simple programming models

• RSS versus SOAP and Web service discovery (UDDI)


Slide 5

“Parsumer” experiences

• Amazon advisory system

– Amazon as a reference system

• eBay reputation system

• del.icio.us, Flickr, youtube, etc, etc

• Wikipedia, Wikitravel, Wikihow

Slide 8

Transforming Access to 3G-850 Everywhere

• 3G-850 Equipment installed into over 5,000 base stations

• Upgrade and migration to a single, Soft-Switch based core

• Upgrade of all legacy 2G hardware and enabling of EDGE

• Voice, Video, high speed data & fixed wireless broadband

over a single network

• Coverage well in excess of current GSM network

Slide 11

Web 2.0 with an IPTV platform

• Not merely TV - a new media experience

– Time shifted TV

– Video on demand

• Targeted advertising

• Education, health care, retail delivered as video rich media

• “Parsumer” TV programming

– Community TV
