Continuity in Yosemite/iOS 8: Which network powers what service?

“If you have the latest Mac and the latest iPhone or iPad running Apple’s latest OSes, and if you have Wi-Fi and Bluetooth turned on, the new Continuity features work like magic,” Iljitsch van Beijnum reports for Ars Technica. “What powers that magic?”

“A wide range of network options, including Bluetooth Low Energy (BTLE), peer-to-peer Wi-Fi, regular local networking, and iCloud/iMessage,” van Beijnum reports. “Each aspect of Continuity actually picks and chooses from these connectivity options, sometimes using more than one.”

“We looked at Continuity while both iOS and OS X were in beta. Now that they are out, we’ve gone back and tested what the released version can accomplish,” van Beijnum reports. “I think this is a complete list of what the current version of Continuity can do, as well as a couple of similar features that Apple doesn’t cover under the ‘Continuity’ umbrella:”

• Handoff, AirDrop, and more will bridge the device gap—if your hardware is up to it.
• Let Macs and iPads send and receive SMSes if you have an iPhone
• Let Macs (and iPads?) make and answer phone calls through an iPhone
• AirDrop files between devices
• AirPlay to an Apple TV
• Remotely control a Keynote presentation
• Start work on one device and Handoff to another in Safari, Maps, Contacts, Notes, Reminders, Keynote, Pages, and Numbers, as well as third-party applications in the future
• Set up an Instant Hotspot

van Beijnum writes, “Let’s take a look at the various network requirements behind each feature.”

  1. The ONLY WAY you can UNITE iOS, and OS X, is to use the same processor for iOS AND OS X. . Can Apple run FCP X on an iPAd ?
    This is the ONE thing MicroSoft has.
    But then again, their Surface 3 with an i7 quad core, is really JUST A LAPTOP with a thin keyboard (Not fooling me MS, ya can get a LOW priced laptop INSTEAD).

  2. • Let Macs and iPads send and receive SMSes if you have an iPhone.

    That’s one of the funniest functions and a great example of how automation looks awesome on paper but may backfire in practice.

    When I received a phone call on my iPhone I walked to the kitchen counter, but halfway out walking there my iPad started ringing, while reaching the iPhone I saw it’s not important call so I hung up, which left the iPad still ringing for 10 seconds. When I got back to the iPad and sat down, the iMac started ringing in the other room.

    I know what the idea is, if I’m not near the iPhone I will just wait (or the call finds me) till the call gets transferred around, which works fine if the iPad is upstairs, the phone in my jacket pocket at the entrance and I sit at iMac listening music in the music room. I would’ve already missed lot of SMS and phone calls because at home, I don’t use the iPhone at all, it really turns to an old style “just a phone” smart phone that usually sits in a dock.
