Intel targets next-generation mobile data with first LTE-enabled multi-mode wireless modem

in General Discussion edited January 2014
With the launch of Samsung's Galaxy Tab 3 10.1, Intel has become just the second company in the world to ship a wireless radio platform capable of communicating on 2G, 3G, and LTE networks in a single package.


Intel's XMM 7160, whose sobriquet lets slip the platform's lineage as an evolution of technology acquired from German semiconductor manufacturer Infineon, is Intel's strongest-yet shot across the bow of rival chipmaker Qualcomm in the fast-growing mobile broadband modem segment.

The 7160 combines two new pieces of kit -- the X Gold 716 baseband chip and the SMARTi m4G transceiver --?into a package the company says can support up to 15 of the 40 LTE bands found worldwide, alongside 3G and EDGE networking. Until now, only Qualcomm could lay claim to shipping a radio with similar capabilities.

In broad terms, the transceiver controls the sending and receiving of signals through a device's antenna system, passing them to the baseband which functions as the "brain" of the radio. The baseband encodes and decodes the signals and communicates with the device's processor to move data in and out.

The combination of transceiver and baseband chip forms the foundation for a device's wireless capabilities, and as a result improvements in power consumption or size can have a tremendous impact on a device's architectural and industrial design. This is the primary area where Intel claims to have an advantage over the competition with the new platform --?the company says the 7160 consumes up to 30 percent less power than rivals with a 12 percent reduction in physical dimensions.

Despite the impressive efficiency gains, Intel still has a high mountain to climb in its quest to become a major player in wireless broadband technology. In addition to missing support for standards like China's TD-LTE, the 7160 lacks the capability to take advantage of next-generation LTE features like carrier aggregation for faster downloads, though the company says these features are coming in the radio's next revision which is expected in early 2014.

Another factor working against Intel is the radio's legacy architecture. While Qualcomm's Gobi line can be integrated into the same package as an application processor, the 7160 must remain a separate part on a device's logic board, taking up valuable space. Intel told AnandTech in August that the company believes it is two to three years away from a complete transition from Infineon's architecture to Intel designs.

After the Samsung victory, Intel may have its eye on a larger prize with the new platform: regaining Apple's iPhone radio business. Apple used Infineon parts in the original iPhone, iPhone 3G, and iPhone 3GS, migrating to Qualcomm silicon with the iPhone 4.

    I think the question here is why are there 40 LTE bands?

    when the article says 3G, can we assume they mean GSM 3G and not both GSM 3G and CDMA 3G (Verizon). You know the thing Qualcomm has a bunch of patents on.   How about Verizon LTE?

    patents and frequency separation between different carriers I would guess.

    If by "GSM 3G" you mean UMTS, then yes, that is what is included here. However, Qualcomm also has patents on UMTS, as UMTS is also based on a CDMA technology. Not sure though what the relevance of these patents is in your opinion. As they are all covered by standards, they fall under FRAND agreements, which means that while Qualcomm will likely earn money also from sales of this Intel product, they are not able to raise prohibitively high fees.


    And for all I know, Verizon LTE is supported.

    My guess is that this is Intel's ultimate goal, as this is an area where Qualcomm may not be able to follow. They could sell an advanced x86 based SoC which contains the graphics processor and the cellular modem together with the main CPU, thus radically reducing size requirements, cost and power consumption. Apple might be the first customer in line for such a package, as they are obviously quite happy with Intel's integrated graphics solutions for most of their Mac lineup already now.


    That's where it gets really interesting though, because they could take such a chip and stick it into an iPhone and iPad without any further changes. There was talk about Macs moving to ARM at some point. Right now I wonder if a change in the other direction isn't more likely mid-term.

    I don't see Apple giving up the LTE bands just added to support China Mobile!

    And, I think Apple may be more interested in low-power WiFi and Bluetooth LE on a separate chip ala the M7. That way, Apple could support these wireless activities on iPhones and iPads while the APU is idle or asleep. I suspect that Apple acquired Massif for this capability.

    However, Apple could cooperate/co-develop this capability with Intel for Mac mobile devices ala Thunderbolt. This could become a bargaining chip for Apple to get Intel to manufacture their A8 APUs.

    Qualcomm are still developing the best BaseBand chip. And if both company Roadmap is any indication, it will continue to be this way in the next two years.

    Intel have some serious work to do to leapfrog Qualcomm.
