According to reports, Apple it has put on hold a technology for iPhones that would have allowed people to send text messages to other iPhones through a 900MHz radio spectrum that is generally used for dispatchers in the public service and manufacturing industries, allowing phones to act as walkie-talkies for text messages.
It seems that this would have been different from the Walkie-Talkie function of Apple for him Apple Watch, which is essentially a FaceTime Push-to-talk (PTT) audio call.
The information says that Apple and Intel were working together on technology, which would have been integrated into Intel chips on future iPhones, before it was suspended.
According to reports, in Apple, the project went through the OGRS Project (pronounced "ogres"), which probably refers to the patents it presented a year ago regarding something called Off Grid Radio Service ("OGRS").
The patents describe a device-to-device wireless communication system that sounds as if it would work, well, outside the network, just as it would with the allegedly archived technology. (Intel allegedly called the Shrek Project effort).
The report says that the internal champion of the project, Rubén Caballero, left Apple at the beginning of this year. The news that shook the industry Apple establishing itself with Qualcomm earlier this year along with the expected movement of Apple from Intel modems to Qualcomm modems could also have played an important role. That change was so great that Intel ended up selling its entire smartphone modem business, which Apple then bought for $ 1 billion.
Putting a walkie-talkie on a phone is not a new idea: industrial workers have used phones with PTT buttons for years, which gives them priority in cellular networks to make walkie-talkie calls. There are also phones with a real walkie-talkie built in, if you want something like that. With information from The Verge.
