The Era of Guerilla Infrastructure

• Guerilla vs. Commercial Infrastructure
• Bottom Up
• Completely Decentralized
• Self-Assembling
• Use at Your Own Risk
• Paves the Way for Commercial Deployment
• Examples
• NSFnet?Internet
• NCSA Mosaic?Web
• Napster?Peer-to-Peer Storage
• SETI_at_home?Peer-to-Peer Computing
• IEEE 802.11?Broadband Wireless Internet
• LamdbaGrid?Global LambdaNet ??

Broadband Wireless Internet is Here Today

• Local Area Wireless Internet Watering Holes
• Ad Hoc IEEE 802.11 Domains
• Real Broadband--11 mbps Going to 54 mbps
• Security and Authentication can be Added
• But, it is Shared and Local
• MobileStar--Admiral Clubs, Starbucks, Major
  Hotels,
• Wide Area InternetCDMA20001xEV
• Peak is 2.4 Mbps downstream, 307 kbps Upstream
• Average is 600 kbps upstream, 220 kbps down
• Extends CDMA Cellular/PCS Voice to IP Packet Data
• UCSD Has Antennas Working With Several Mile

Elektrosmog is the Embodiment of 3G Skepticism
Founded in Stockholm on August 30, 2000,
Elektrosmog is a discussion group for public,
wireless access to the Internet over non-telecom
networks, such as the Wireless LAN standard IEEE
802.11b. Membership is open and doesn't cost
anything. The project grew out of a skepticism
towards the claims of the telecom industry
regarding the usefulness and success of the
future "third generation mobile telephone
systems" as the only means to implement "the
wireless Internet". This skepticism culminated in
the fall of 2000 with the European telecom
operators' applications for radio frequency
bandwidth for the future UMTS networks. We
envision a cloud of free Internet connectivity
that will cover most inhabited areas. The
coverage might be spotty, vary over time, and be
hard to control or predict, just like a fog or
smog. 369 members as of June 1, 2001

Will The Planned Global Rollout of 3G Proceed as
Planned?

• Lack of 3G Global Standardization
• Constrains Economies of Scale
• The Economics of Telecom
• The Huge Debt Load
• The Investment in 3G Buildout
• Is There a Business Case to Recoup?     
• Technological Breakouts
• IEEE 802.11 Buildout
• 3G Data Only Can Deploy Now (CDMA20001xEV)
• Will They Skim the Cream of the 3G Market?
