Greg,
If you are off the grid, you can use satellite communications. Here in the states, we have Hughes Net (static operations). If you are moving around, your best bet would be a portable satellite radio. Those can get kind of pricy, so there are some outfits that will rent them for project work (see below). http://www.mackaysatellite.com/bgan-thrane-explorer-700-weekly-rental.html?_ __store=default Thanks, Alex Mahrou Rocky Mountain Geospatial Consultants Rockymountaingeo.com <http://twitter.com/#!/AlexMahrou> Twitter: AlexMahrou Direct: (720)244-3695 From: [email protected] [mailto:[email protected]] On Behalf Of joe brickley Sent: Tuesday, March 22, 2011 8:38 AM To: [email protected] Cc: [email protected] Subject: Re: [Geowanking] Off-the-grid SMS or data transfer Depending on the application it may also be worth looking into long range wifi. http://en.wikipedia.org/wiki/Long-range_Wi-Fi Joe On Tue, Mar 22, 2011 at 4:05 AM, Anselm Hook <[email protected]> wrote: http://reviews.cnet.com/gps/spot-connect-satellite-messenger/4505-3490_7-344 67097.html <- this thing is coming out soon - maybe it is an option? a On Mon, Mar 21, 2011 at 8:10 PM, Greg Yetman <[email protected]> wrote: > Hi, > We have a project that requires sending field data (including position > measured from GPS) back to a server in areas without cell phone coverage.
