The project was internally known as “Project OGRS” (or Off Grid Radio Service), and would have used 900 megahertz radio spectrum to allow iPhone users to communicate while offline. The same technology is used for dispatch radio communications.
The report doesn’t say how far along the project was or what issues caused Apple to stop development. Apparently, one of the project’s biggest evangelicals recently left Apple.
It’s unclear if Project ORGS will show up in a future iPhone now that the initiative has been shelved. With Apple now developing its own in-house modems, however, there’s a chance we could see something show up in the future.
