How to build and implement DTN based internet access with gender and cultural sensitive approach (eLearning-DTN) is the name of a unique learning platform that explains how a network step-by-step can be established in areas that lack internet infrastructure. The technology that is used is called Delay Tolerant Networking (DTN), originally created by NASA for space communications and taken further by the N4C consortium. N4C research and development is in turn built on projects carried out in Swedish Lapland since beginning of year 2000. eLearning-DTN is a how-to-do-it course that transfer innovation from that development (www.n4c.eu) into practical usage. The development of the eLearning-DTN platform was financed by EU:s Life Long Learning program.


The InterPlanetary Networking Special Interest Group (IPNSIG) aims to realize a functional and scalable system of interplanetary data communications before the year 2020. Membership in IPNSIG is international and interdisciplinary. The IPNSIG has promoted the eLearning-DTN courses that now are available. Read more about it:


eLearning-DTN explains how DTN can be used and how people can build their own network. The course is free of charge and the investment cost for the network is low as hardware that is used is commercial off-the-shelf (COTS) ready-made and available for sale equipment that can be bought everywhere. Software that is used is mainly Open Source Software (OSS). Partner in eLearning DTN has been IPN, Coimbra, Portugal, MEIS, Slovenia and Power Lake AB in Sweden. Work has been coordinated by Luleå University of Technology (LTU) in Sweden.
