Re: [Int-area] GPS over wifi

[Rob Brew <[e-mail]>]

Dear all.

Having received the post from Alex I have responded. If you would rather I
move this RFC to antarea I will do so.  Personally I feel it's more of an
internet problem as GPS is being delivered using HTTP protocols.

By this I mean if there is no wif-fi connection and no GPS connection the
phone's GPS
location software can reach out to such a wireless network without an ssid
for the purposes of gaining it's GPS location. This would require some
reprogamming of GPS location software by Google and Apple.

All that is needed for this to happen is to reconfigure underground routers
and set up a server to deal with the requests, having populated a table on
the server of GPS locations.
