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


6/27

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


7/27

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


8/27

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

Shared

communicationsinfrastructure tends tobe asynchronous

Considerat ions

& Quest ions

Lack of required talentwithin developingcountries to develop andimplement WiFisolutions

Access to requiredresources customsduties

Need ugly ruggedhardware for ruralenvironment

Licensing = time andmoney

Role of Voice/VOIP? Impact on incumbent

telcos?
