The iPhone 5 Won't Have 4G LTE, Here's Why

Apple's purported iPhone is generally referred to as the iPhone 5, though recent reports have suggested it could be called the iPhone "4G" should it be enabled with the 4th generation cellular wireless standard.

Although there has been some debate about what constitutes 4G technology, here our some reasons why Apple's forthcoming smartphone won't have 4G LTE.

LTE technology hasn't advanced so far as to be integrated in a slim, elegant design. The LTE chipsets are a separate modem that stands on top of or next to an existing chipset and for this reason, there are no slim phones yet that have integrated the LTE technology.

A slim design is definitely one of Apple's priorities and the company wouldn't be willing to sacrifice it for the LTE technology. Furthermore, sticking to the present HSPA network would keep the battery running all day, whereas introducing LTE would greatly diminish battery life - again, a sacrifice Apple is not likely to make.

Later next year could also see the arrival of 'single-chip LTE solutions' from the likes of Qualcomm, enabling a slimmer handset with improved battery life, PC Mag reports.

AT&T and Verizon, iPhone's current carriers are also developing LTE technology, but Verizon is one step ahead. AT&T's network won't be widespread until mid-2012, as is the case with many other global carriers.

But AT&T will most probably have HSPA 14.4, which it considers to be 4G, although no other company does, and possibly even HSPA+ 21 - which is more widely accepted as 4G. This could lead to the situation where both carriers will get the upcoming iPhone at the same time and AT&T could call the device "4G", but Verizon won't be able to.
