It’s the usual annoyance when your phone won’t connect to the network. But for firefighters and paramedics and police officers, it can be a matter of life and death.

Apple has a patent with which it wants to fight robberies in its stores
Apple would like to get around all this by teaching iPhones to share network connections with each other. The technology would work similarly to regular internet connection sharing via a hotspot feature. One of the team members who had a network connection could then pass it on to the others via Wi-Fi. Apple even claims that using so-called Proximity Services is in some ways more advantageous than connecting through an access point. It can make better use of bandwidth, it can be faster and less energy intensive. Another use of the technology would be for selected iPhones to communicate with each other directly, even if no carrier is available.
