The world of mobile devices is a curious one. Handset manufacturers are always raising the bar for features in both hardware and software in order to convince customers to use their device. Yet, no matter how much innovation goes into the handset the vendors are still very reliant upon the whims of the carriers. Apple knows this perhaps better than anyone
In Your FaceTime
FaceTime was the first protocol to feel the wrath of the carriers. Apple developed it as a way to facilitate video communication between parties. The idea was that face-to-face video communications could be simplified to create a seamless experience. And it did, for the most part. Except that AT&T decided that using FaceTime over 3G would put too much strain on their network. At first, they forced Apple to limit FaceTime to only work with wireless connections. That severely inhibited the utility of the protocol. If the only place that a you can video call someone is at home or in a coffee shop (or on crappy hotel wireless) that makes the video call much less useful.
Apple finally allowed FaceTime to operate over cellular networks in iOS 6, yet AT&T (and other carriers) restricted the use of the protocol to those customers on the most current data plans. This eliminated those on older, unlimited data plans from utilizing the service. The carriers eventually gave in to customer pressure and started rolling out the capability to all subscribers. By then, it was too late. Apple had decided to take a different track – replace the need for a carrier.
Message For You
The first shot in this replacement battle came with iMessage. Apple created a messaging protocol like the iChat system for Mac, only it ran on iPhones and iPads (and later Macs). It was enabled by default, which was genius. The first time you sent an Short Message Service (SMS) text to a friend, the system detected you were messaging another iPhone user on a compatible version of software. The system then flipped the messaging over to use iMessage instead of SMS and the chat bubbles turned blue instead of green. Now, you could send pictures of any size as well as texts on any length with no restrictions. 160-character limits were no longer a concern. Neither was paying your carrier for an SMS plan. So long as the people you spoke with were all iDevice users the service was completely free.
iMessage was Apple’s first attempt to sideline the carriers. It removed a huge portion of their profitability. According to an article published at the launch of iMessage, carriers were making $.20 per message outside of an SMS plan for data that would cost about $.0125 on a data plan. Worse yet, that message traversed a control channel that was always present for the user. There was no additional cost to the carrier beyond flipping a switch to enable message delivery to the phone. It was a pure-profit enterprise. Apple seized on the opportunity to erode that profitability.
Today, you can barely find a cellular plan that *doesn’t* include unlimited text messaging. The carriers can no longer reap the rewards of a high profit, low cost service like SMS because of Apple and iMessage. Carriers are instead including it as a quality of life feature that they make nothing from. Cupertino has eliminated one of the sources of carrier entanglement. And they’re poised to do it again in iOS 7.
You Can Hear Me Now
FaceTime Audio was one of the features of iOS 7 that got swept under the rug in favor of talking about flat design or parallax wallpaper. FaceTime Audio uses the same audio codec from FaceTime, AAC-ELD, to initiate a phone call between two iDevice users. Only it doesn’t use the 3G/LTE radio to make the call. It’s all done via the data connection.
I tested FaceTime Audio for the first time after my wife upgraded her phone to iOS 7. The results were beyond astonishing. The audio quality of the call was as crisp and clear as any I’d every heard. In fact, I would compare it to the use of Cisco’s Wideband G.722 codec on an enterprise voice system. My wife, a non-technical person even noticed the difference by remarking, “It’s like you’re right next to me in the same room!” I specifically tried it over 3G/LTE to make sure it wasn’t blocked like FaceTime video. Amazingly, it wasn’t.
The Mean Opinion Score (MOS) rating that telephony network use to rate call clarity runs from 1 to 5. A 1 means you can’t hear them at all. A 5 means there is no difference between talking on the phone and talking in the same room. Most of the “best” calls get a MOS rating in the 4.1-4.3 range. I would rate FaceTime audio at a 4.5 or higher. Not only could I hear my wife clearly on the calls we made, but I also heard background noise clearly when she turned her head to speak to someone. The clarity was so amazing that I even tweeted about it.

FaceTime Audio calling could be poised to do the same thing to voice minutes that iMessage did to SMS. I’ve already changed the favorite for my wife’s number to dial her via FaceTime Audio instead of her mobile phone number. The clarity makes that much of a difference. It also helps that I’m not using any of my plan minutes to call her. Yes, I realize that many carriers make mobile-to-mobile calls free already. However, I was also able to call my wife via FaceTime Audio from my iPad as a test that worked perfectly. Now, I not only don’t use voice minutes but have the flexibility to call from a device that previously had no capability to do so.
Who Needs A Phone?
Think about the iPod Touch. It is a device that is very similar to the iPhone. In fact, with the exception of the cellular radio one might say they’re identical. With iMessage, I can get texts on an iPod touch using my Apple ID. So long as I’m around a wireless connection (or have a 3G MiFi device) I’m connected to the world. With FaceTime audio, the same Apple ID now allows me to take phone calls. The only thing the carriers now have to provide is a data connection. You still can’t text or call non-Apple devices with iMessage and FaceTime. However, you can reduce the amount of money you are paying for their services due to a reduction in the amount of minutes and/or texts you are sending. That should have the mobile carriers running scared.
I once said I would never own a cellular phone because sometimes I didn’t want to be found. Today, I get nervous if mine isn’t with me at all times. I also didn’t get SMS messaging at first. Now I spend more time doing that than anything else. Mobile technology has changed our lives. We’ve spent far too much time chained to the carriers, however. They have dictated what when can do with our phones. They have enforced how much data we use and how much we can talk. With protocols like FaceTime Audio, the handset manufacturers are going to start deciding how best to use their own devices. No carrier will be able to institute limits on minutes or texts. I think that if FaceTime Audio takes off in the same way as iMessage, you’ll see mobile carriers offering unlimited talk plans alongside the unlimited text plans within the next two years. If 50% of your userbase is making calls on their data plans, they need for all those “rollover” minutes becomes spurious. People will start reducing their plans down to the minimum necessary to get good data coverage. And if a carrier decides to start gouging for data service? Just take your device to another carrier. Or drop you contact in favor of a MiFi or similar data-only connection. FaceTime Audio is the beginning of easy Voice over IP (VoIP) calling. It’s the end of the road for carrier dominance.
