Abstract: The IPv4 address space is a legacy allocation dedicated to Amateur Radio Data Communications (www.ampr.org). The allocation to Sweden is  The space facilitates deployment of an independent, non-commercial part of Internet serving society based on amateur radio rules and operated by volunteers. It can be made available to primary organisations responsible for emergency managementl, e.g. during accidents and extreme weather situations, and can be used for research, education and innovative development of emergency management systems. The AMPR address space has until recently had only one connection to Internet, announced out of  University of California in San Diego (UCSD). Since May 2013, the Swedish allocation is also announced out of SUNET,the Swedish University Network. The partnership between  the Sweidsh radio amateur community and SUNET is based on cooperation to make important amateur radio resources available for emergency communication.  Also other infrastructure owners have shown an interest in joining in this partnership.

A very active pioneering period in the 1990ies faded away after the turn of the millennium shadowed by the Internet development. Since then regulatory and technical development, and the partnership with SUNET, have motivated a restart. The radio amateur clubs are now invited to connect useful resources to Internet via AMPRnet. Gateways AMPRnet/SUNET are deployed at SUNET points of presence all over the country.  Examples of useful resources include remotely controlled HF-stations, VHF/UHF-repeaters, sensor networks for environment monitoring, radio beacons, etc.

Important goals for AMPR in Sweden include to contribute to increased redunace, robustness ad security of the Swedish communication infrastructure. Radio amateurs have access to masts for redundant radio links and can smetimes get access to spare fiber capacity due to their non-commercial and public good nature.  Power supply is secured via powerlean solutions, use of alternative renewable energy sources and innovative power storage systems. Security solutions are developed together with the univeristy networks.  Technically, since the unique resources of AMPR is the IPv4 address space, IP-based Internet technology is in focus. Integration with other technologies is supported whenever possible. Audio, video, data, all sorts of services and applications are considered. The same goes for all sorts of links to cary IP-packets. Not only amateur radio bands, but also license exempt spectrum and frequency bands that can be used for experiments at low cost, such as unused TV-channels.  For implementation,  open and robust low-energy solutions are a priority, both on the hardware and software sides.
