While we are fully sympathetic with a focus on wireless in the access network, we have for long been advocates of bringing optical fiber as close as possible to the user and for moving from point-to-point or ring architectures in current fiber networks to mesh architectures. In this context, reports of a breakthrough in optical communication makes us happy. Of course, we understand it takes a little while to go from the pages of Science to reducing repeaters in actual optical fiber cables. One way to understand the challenge of sending data through fiber-optic circuits is to imagine a person shouting to someone else down a long corridor. As the listener moves farther away, the words become fainter and more difficult to discern as they echo off the walls.
Since Bangladesh was connected to the world through an undersea cable a year or so ago, it has had great difficulty keeping connected. The dry portion of the cable snapped twice in August 2007. Contrast this with Sri Lanka and Pakistan, which have had problems only once each in the past five years. Obviously redundancy is a key issue in Bangladesh. :: bdnews24.
Vint Cerf, one of the fathers of the Internet now at Google, appears to see a key role for the mobile especially in developing countries. ACM: Ubiquity – Cerf’s Up Again! — A New Ubiquity Interview with Vint Cerf CERF: Well, certainly that has happened in the sense that the mobile telephony has allowed the provision of communication services, and let me include in that Internet access, in places where it was very difficult to obtain that service before. And so, I think roughly the number of telephone terminations has more than doubled in the last five years. It’s gone from a little over a billion to a little over 2.
