The WirelessRevolut ion
Wireless = leapfroggingopportunities
But what kind ofwireless? Radio links (1-100Mhz) Cellular/ WLL Satellite/VSAT WiFi LAN/WAN
Insight:Same factorsdriving WiFi revolution indeveloped world candrive a revolution indeveloping world: Low cost for users and
providers
East of setup, use andmaintenance
Bandwidth and scalability Spectrum delicensing

Vis ion
Local entrepreneurswithin developing
countries will use WiFito: Overcome infrastructure
cost barriers
Innovate and experimentwith applications andcontent
Stimulate thedevelopment dynamic forrural first milecommunities
Grow the infrastructureaccording to first mile
needs and demands,scaling up to universalbroadband connectivity

The RuralICT Mark et
Latent demand forinformation and
communication services The needs of the end-
users come first = thefirst mile
But need low-risk seed
infrastructure to seewhat is demanded
User adoption takes time
Service adoption alsotakes time

AsynchronousIs Suf f ic ient
ICTs introduced asshared resource
But this hasdrawbacks for real-time infrastructures:
High level of adoption
required to achievecost recovery
Who am I going tocall? problem
