What Is Attached to Our Global ICT Infrastructure?
How much gear is attached to the edges of our global ICT infrastructure? Our estimate has now reached 17 billion items, driven by mobile and broadcast devices. The World Bank tells us that the western hemisphere now has more mobile phones than people. This is an average number; 30% of Latin America's population lack access to mobile services.
|Device Type||2012 Estimate
|Cable, Sat & DTV STBs, DVRs||0.8|
|Consumer Broadband ||0.4|
|Personal Music Players||0.2|
|Satellite TV Dishes*||0.2|
 Modems, routers, residential gateways, etc.
 Portable GPS units for driving, boating, backcountry, etc. excluding GPS-equipped smart phones and tablets
Mobile devices - phones, tablets, navigation systems - are the largest segment, representing over 6 billion pieces of e-gear. (Some estimates put the 2012 total as high as 7 billion.)
Broadcast devices - radios, televisions, STBs - are the second largest segment at over 4 billion. Broadcast is the original broadband wireless ICT infrastructure. It is still expanding worldwide even as it converts from analog to digital and uses many ICT technologies. Broadcast shares with other forms of ICT the same issues of resource consumption, toxin emissions, and e-waste.
We examine dozens of reports, studies and forecasts from around the world. We evaluate their data and determine how to incorporate it into our edge gear model. Cross-referencing and consistency checks give us confidence in the numbers. The comment below from 2009 illustrates some of the challenges in doing this.
