Looks like they ARE using a pager network http://www.ambientdevices.com/cat/orb/orborder.html Better coverage. Wireless coverage from the Ambient Information Network covers over 90% of the U.S. population. Check if you're covered. >From the FAQ https://myambient.com/java/my_devices/help.jsp#9 Is there a monthly cost? The Ambient Device will work perfectly with no monthly fees, we at Ambient have a firm belief that every product should be useful without having to pony up ever month. We do offer some types of information that cost us more to operate, these Premium Channels we do have to charge a monthly fee for - but are completely an optional choice on your part. Basic channels, like stock market indexes or weather in major cities are always free. > -----Original Message----- > From: piclist-bounces@mit.edu > [mailto:piclist-bounces@mit.edu] On Behalf Of William Chops Westfield > Sent: Friday, July 01, 2005 9:13 AM > To: Microcontroller discussion list - Public. > Subject: Re: [EE]: ambient orb > > > On Jun 30, 2005, at 11:02 PM, Alison Lewis wrote: > > > Is it a cell phone network, or is > > there something else going on there?
