Further analysis of the logic board photos reveal that the iPhone 6 will have Qualcomm’s MDM9625 LTE Modem, confirming earlier reports of the device supporting LTE Advanced. These next-generation LTE Advanced networks are slowly rolling out around the world, and can provide theoretical speeds of up to 150 Mbps, compared to the iPhone 5s, iPhone 5c and iPhone 5’s LTE modem’s 100 Mbps speed.
Some reports suggested that Apple could use an even higher-end Category 6 LTE modem with speeds of up to 300 Mbps, but if recent leaks are to be believed, Apple’s opting for a moderate improvement rather than one that triples the theoretical speeds.
Part of the speed benefits of the MDM9625 and new LTE-Advanced technology compared to earlier generations of modems comes from the use of carrier aggregation to combine channels for greater bandwidth. With the MDM9625, this carrier aggregation requires a pair of companion chips, a WTR1625L transceiver chip and a WFR1620 chip. These chips appear to be located on the opposite of the iPhone 6 logic board from the LTE modem itself.
A China Telecom ad suggested that the iPhone 6 will be available in a single model that would support all carriers rather than in separate variants for each carrier specific technology.
Apple will unveil the iPhone 6 on September 9th, with the launch expected to be on September 19th. The device is expected to feature an all-new ultra thin design with narrower bezels and rounded edges. It is also expected to include Apple’s new A8 chip, improved Touch ID fingerprint sensor, and an improved 8-megapixel camera with optical image stabilization.[via MacRumors]
