Dear all. I have submittetd the following draft RFC for approval.
Obviously whilst underground mobile phone users at public locations, such as the London underground, will not be able to know their GPS location, as the GPS signals cannot penetrate the earth. I have submitted a RFC draft at https://tools.ietf.org/html/draft-brew-intarea-underground-01 to bypass this problem, as well as a server application in Java at https://github.com/rydal/underground . As we know the IP Address contacting the server the server contains a map containing the GPS location of each underground site, as referenced by IP address. The returns the phsycial GPS location and name of the site as a JSON array. To prevent false servers reporting inaccurate information https can be used to verify the authenticity of the server. Providing this service to mobile phone user's without a current WIfi connection i propose going one stage further, create a hidden wireless network wih the name ".location". In cases where no GPS location can be found a mobile phone's GPS system can be programmed to seek such a network providing the same service. This would require alterations to th servics as provided by mobile phone providers such as Apple and Android. If you are interested in this concept please review it (and my code), and maybe it will become something. For a video demonstration of this service please check the link at the github site. Thanks, Rob Brew.
