Relative to the iPhone 4’s antenna issues everyone’s howling about, I’m trying to square this with this. Is the software really displaying the reception-strength bars wrong, or is it really a hand-position-muffles-antenna issue?

Independent, Apple loses an opportunity to shed its ‘too authoritarian’ image by stone-walling, especially with it’s somewhat shocking press release on the topic, parodied here by @gruber.

The Anandtech review – using real reception measurements not the graphical bars – indicates that iPhone 4’s antenna is better than earlier models in areas of low reception. This is great news for folks who have to endure poor connectivity in their usual locations, but it does nothing to explain the mysterious death grip issue – whereby holding the phone in a normal and comfortable way reduces the antenna’s effectiveness.

It’s important to point out that all phones employing the built-in-antenna or antenna-inside-case paradigms can suffer from attenuation just being held in the hand. It’s just that Apple’s problem seems dramatic – and surprisingly like something that would/should have been caught early on in the product cycle.

From my viewpoint – I’m not an iPhone owner, though I have had a long succession of smartphones – it makes perfect sense for iPhone 4 owners to get themselves a bumper-type case which reduces (resolves?) the attenuation problem. The double benefit: normal handling doesn’t ding up the phone’s case and even an occasional drop will be tolerated. To those who would get pissy over spending $29 on such a case, I’d simply ask that you take a long look at what the iPhone is costing you over the two-year period of your contract (upwards of $2000 including all fees for hardware and services) and recognize that perhaps $29 is worth it to protect that investment.

UPDATE: Here’s a great, recent, review of the iPhone 4 discussing both the quality of the device compared to earlier models (and Android devices) and the antenna issue (which, it’s claimed, happens only under low-connectivity conditions).

AT&T is ending its unlimited data plan. Owners of Apple’s iPhone – who account for a very high percentage of data traffic on AT&T’s network – will be affected. But I predict most iPhone users will be affected positively. That’s because AT&T claims that 3% of its users account for 40% of the traffic. Once those 3% of users are reigned in – by making it more expensive to over-consume bandwidth – everyone on AT&T will start to see better performance, particularly in the very congested areas (New York and San Francisco in particular). And, the 97% of typical users will pay less for the bandwidth they do consume.

Frankly, you don’t need an economics degree to understand this situation. What AT&T is doing is arresting a true Tragedy of the Commons situation on their network. AT&T’s network approximates a public resource – a network utilized by a large customer base with widely differing aspirations and needs. Some of these users – a tiny percentage – have destroyed the resource by making overly-aggressive use of it, to the point the some users can’t even acquire access to the network at all for reasonably long periods. Everyone – including, curiously, the over-users – is frustrated.

Certainly, AT&T’s problem is not created solely by network over-use. AT&T has internal policies for managing its network, and the company in effect “places bets” on how the network will be used in order to craft the best possible access characteristics. AT&T also decides when, and how, to upgrade its network. None of us is privy to any of these considerations, and we can only believe AT&T’s public announcements on these matters. But overuse has seriously limited the tools AT&T has at its disposal. Something had to give.

It should be noted that Carnegie Mellon University – one of the nation’s most prestigious Computer Science schools – has instituted a fairly bold policy that throttles bandwidth available to users who have consumed too much in a given period of time. Students are subscribed automatically to CMU’s network, and there is no additional fee for network over-use. But this policy is deemed prudent here because it limits the tragedy of the commons situation (which affects all users). In the mobile arena, TMobile is already employing traffic shaping.

What sorts of usage consume lots of bandwidth? As explained here, streaming media, peer-to-peer file sharing and file download account for 66-75% of mobile bandwidth usage; web browsing 25-33% of usage – in both cases, dependent on region. To quote:

“…voice (VoIP), instant messaging, email and all other apps besides video and Web applications are a negligible driver of bandwidth consumption”

That’s right – the network is not being over-consumed by the Blackberry crowd, heavy users of Facebook, or people exchanging IMs. It’s being overused by consumption of media – streamed or downloaded files, legal and illegal. If you’re one of the people who’s got SlingBox Mobile, or a jailbreak phone running iHulu, or just can’t get enough AirSharing – well, you’re one of the people in AT&T’s crosshairs. And deservedly so (in my opinion).

Frankly, despite all the hype or what it’s called – 3G, 4G, LTE, WiMax, EV-DO – the mobile networks are simply not ready for high levels of media consumption. So those who do consume in this fashion need to compensate those harmed (impractical in this case) or pay more for over-consumption (which, indirectly, will compensate those harmed).

Please note that the altruistic blogosphere will no doubt erupt in anger over this change. Curbs on our freedom! Control by the Wicked Overlord! A slippery slope to usage monitoring, privacy invasion and government censorship!!! All very odd for a group of people normally in favor of spreading the most benefit to the most people (and disallowing the maximum benefits from accruing to the privileged few).

Gartner validates what we’ve all been feeling – in 3Q2008, worldwide growth of smartphone sales was at its weakest point since tracking began (at 11.5%).

North America was a bright spot, however, growing at 68% with Blackberry and iPhone devices totaling 70% of sales. In Europe, Apple made great progress – moving to number two behind Nokia. MacOSX is now the third most popular smartphone operating system worldwide. Windows Mobile is taking a beating – with numbers down 3% – another illustration of the importance of brand in the mobile marketplace.

An interesting side note: Gartner monitors smartphones from manufacturer HTC only on its own-branded devices. HTC meanwhile is the ODM for numerous other brands and for carrier-branded (predominantly) Windows Mobile devices (like the TMobile Wing). HTC also manufactures TMobileUSA’s G1 device, based on the Google Android operating system (which Gartner is not measuring as a separate category yet). One wonders where inclusion of these numbers would put HTC in the charts!
