Apple is about to announce new iPhone series with iOS7 in a couple of hours but any modem features are not leaked yet to public.
In this section, I want to expect possible LTE modem options for iPhone5s and iPhone5c respectively.
MDM9625 is latest LTE modem chipset provided by QCT(Qualcomm CDMA Technologies) but just opened recently reletively.
It supports multimode multiband radio access technologies and has been used with upgraded modem on each iPhone announcement.
There are two options for iPhone5s, one is MDM9625 and another is MDM9615. However iPhone5s is flagship model of Apple so MDM9625 is very promising candidate for it.
MDM9615 is still good candidate for iPhone5s and iPhone5c at the same time because of downsizing BOM(Bill of material) cost and use same design factor.
Big difference between MDM9625 and MDM9615 is Peak Data Rates and LTE-A features as below table.

Apple is still focusing on high margin by reducing price of each components for example, AP(Application processor), Nand Memory and LTE modem.
And there will not be quite demanding of LTE-A especially, Carrier Aggregation, from operators so MDM9615 will be a good prop until launching iPhone6 next year.
Let's wait and see how Apple will decorate new iPhones' radio feature from coming Tim Cook's key note speech.
