Iphone 4s what does extended mean

The idea was for everyone to be using the same cat; that way, manufacturers could exploit economies of scale. This would mean cellphone companies could make fewer models that worked in more places in the world, infrastructure vendors could manufacture interchangeable cell towers and radio stacks, and end users could move their cellphones between countries or between operators within the same country.

GSM was by far the most successful second-generation wireless 2G standard. Even as consumers were becoming familiar with the technology, however, the next global standard -- Universal Mobile Telecommunications System UMTS -- was being developed.

The ITU is the United Nations agency charged with coordinating standards for digital communication among all member nations. Lather, rinse, repeat: as gadget blogs filled up with brand new 3G handsets in the early s, the ITU pushed on and defined target goals for next-generation networks to hit.

These were defined in a standard called IMT-Advanced , which was finalised in The standards process churns slowly; the actual specification for IMT-Advanced was finally adopted early in Rather, ITU standards are sort of like aspirational goals for technology vendors to achieve. Meanwhile, of course, mobile vendors have mouths to feed so they need to keep selling us shiny geegaws. Again, these enhance data speeds over and above what the initial versions of 3G could offer, but far short of the requirements for IMT-Advanced -- and rather closer to 3G performance than they are to "4G.

These intermediate standards are a replay of what happened with 2G. HSCSD boosted download speeds to This led to EDGE often being referred to as "2. Apple coded the original iPhone OS releases to communicate to the customer if they were on a GPRS network with a dot or a EDGE one with an 'E' -- the difference is significant, and the user has a better experience if he or she knows what performance to expect before using the device.

Some people do that, but it wasn't enough for the marketing departments at some big cellular operators. It's always easier to sell things to people when you don't have to make them read a post as long as this one before they understand what they are buying, and it's even easier still when you've taken the last number and turned it up one louder -- hence digital camera's megapixel myth.

So they did just that, without as much as a by-your-leave, starting in None of these networks met the IMA-Advanced speed threshold, nowhere near it -- but that did not stop the carriers from taking advantage of the lack of a technical standard for "4G" to gain some branding bonus. Now Apple has joined in, in a surprising move, seeing as how it is normally lauded for being immune to carrier interference.

Update : As commenters have correctly pointed out, in the ITU let out a heavy sigh and acknowledged what carrier marketing had already done to confuse the marketplace. Since 4G has no official meaning within the standards process, one can't say authoritatively that the indicator is technically wrong; only that it is decidedly confusing.
