Mobile devices are quickly becoming much more than just a means to make a voice call. Top of the line devices are now being tested for their ability to be the brains for satellites. But perhaps more important than their capabilities is that they are the most rapidly disseminating technology in human history. Soon only a tiny minority will lack an always on link to the network. What’s more astounding is that this graphic is five years old and currently there are 6 billion mobile phone subscriptions, though duplicates reduce the number of users.

This ubiquity is going to have an unparalleled impact on how just about every facet of social organization operates. The next generation is growing up with an intuitive grasp of making the most of their new technical assistants, and they will incorporate them into new workflows for organizations that are unthinkable at the moment.

The complement to price decreases that are resulting in such tremendous uptake is the exponential increase in capabilities in even the simplest devices. More and more devices are benefiting from applications that enable them to collect data, profit from information services designed to be accessed via SMS or WAP, and increasingly connect directly to the internet over wireless broadband networks. The addition of GPS radios and cameras drastically improves the ability to verify information collected with these devices.

Soon regardless of where in the world you are, you’ll only be a few miles–at the most!–from the nearest node of our globally connected culture.


Three days later as if to highlight the challenges that still remain the Seacom fiber optic cable connecting east Africa to India and Europe failed. The disruption brought connection speeds in Tanzania and Kenya to a crawl while Uganda and Rwanda switched back to more expensive satellite connections. Submarine cables are difficult to repair and vulnerable to accident or malfeasance. In 2008 large parts of the Middle East and Asia were left without connections after an anchor severed the FLAG cable in the Mediterranean.

The challenges don’t end once a cable is laid; extending the connection to rural locations is difficult and costly. Copper wire used for low bandwidth lines is frequently stolen with South Africa alone estimated to lose $1 billion dollars because of replacement costs. These examples highlight both the potential and vulnerability of an increasingly sophisticated communications infrastructure.
