Perma-net and Nearly-net

April 1st, 2003 · No Comments

Clay Shirky writes about 3G in the context of what’s happening with WiFi, starting by describing the two types of networks that are there around us:

Call the first network “perma-net,” a world where connectivity is like air, where anyone can send or receive data anytime anywhere. Call the second network “nearly-net”, an archipelago of connectivity in an ocean of disconnection. Everyone wants permanet — the providers want to provide it, the customers want to use it, and every few years, someone announces that they are going to build some version of it. The lesson of in-flight phones is that nearlynet is better aligned with the technological, economic, and social forces that help networks actually get built. The most illustrative failure of permanet is the airphone. The most spectacular was Iridium. The most expensive will be 3G.

The idea [with 3G] is that users want to be able to access data any time anywhere. This is of course true in the abstract, but there are two caveats: the first is that they do not want it at any cost, and the second and more worrying one is that if they won’t use 3G in environments where they have other ways of connecting more cheaply.

The nearlynet to 3G’s permanet is Wifi (and, to a lesser extent, flat-rate priced services like email on the Blackberry.)

Wifi is like the cell phone, only useful at either end of travel, but providing better connectivity at a fraction of the price. This matches the negative feedback loop of the airphone — the cheaper Wifi gets, both in real dollars and in comparison to 3G, the greater the displacement away from 3G, the longer it will take to pay back the hardware investment (and, in countries that auctioned 3G licenses, the stupefying purchase price), and the later the day the operators can lower their prices.

The lesson of nearlynet is that connectivity is rarely an all or nothing proposition, much as would-be monopolists might like it to be. Instead, small improvements in connectivity can generally be accomplished at much less cost than large improvements, and so we continue growing towards permanet one nearlynet at a time.
