The DCU-S.O.S. - Set-up in April 2012 by the Democratic Commonwealth Union Micronation (under a dual Communications Federation and Civil Defence Bureau mandate), is a civil intiative to provide a back-bone of emergency communications to civil society in the event that other forms of communications become unreliable or are "cut-off" accidentally or deliberately.
The network is dependent on the idea of citizens' participation and co-operation, of which there are many communication mediums and "citizen bands" in use now by so many for everyday activities (both business and leisure) and that only a handful of people know of the benefits that these "citizen bands" can provide in an emergency if properly administered.
The DCU, as the foremost pioneer of ultra-local communications in the micronational community, has realised a need for this sort of infrastructure to be in place to cater for any emergencies that may arise, as well as the utilisation of skills and resources of ordinary people to make a difference.
This need was most evident during the English Riots in Summer 2011, where ordinary people could not access any police or fire services and risked getting caught up in the esculating violence and muddle of mismanagement by the authorities: many citizens even took matters into their own hands, both during (as an auxilary "peace officer" presence) and afterwards (in the clean-up operation that took place) which the UK Coalition Government claimed was down to "sucessful policing", which as we all know wasn't the case and risked the lives of many, particularly without any proper communications infrastructure to deal with emergencies and situation analysis to those who had no choice but to take action themselves to stop the esculating of the situation.
The scheme for an emergency civilian network is not new and indeed has been trialed out in the United States (known as the National SOS Radio Network: http://www.nationalsos.com/index.html) for use in such instances as for the rescue of stranded persons in a hurricane scenareo, in which the use of the Family Radio Service co-ordinate with GMRS Radio to give a very simple, but highly effective emergency network - this relies on educating the public, businesses, organisations and emergency or civil defence services about the way such a network can exist.
The DCU SOS Network is however likely to be a much wider programme due to the number of potential communications options which are now available to the general public (From CB, PMR446, all the way up to set-channel "business band" radio, along with other methods.
In addition, mobile telephone, landline, WiFi, text, Multi-Media Messaging amongst others will compliment into a robust warning system in times of severe emergency. An example of which can be found on the "How It works" tab.
