Back in December of 2016, Qualcomm and Microsoft announced a partnership to bring Windows to platforms based on the Snapdragon platform. Not Windows RT redux, not Windows mobile, not Windows Mini, full blown Windows with 100% application support and compatibility. It was a surprising and gutsy move after the tepid response (at best) to the ARM-based Windows RT launch several years ago. Qualcomm and Microsoft assure us that this time things are different, thanks to a lot of learning and additional features that make the transition seamless for consumers.
The big reveal for this week is the initial list of partners that Qualcomm has brought on board to build Windows 10 system around the Snapdragon 835 Mobile Platform. ASUS, HP, and Lenovo will offer machines based around that SoC, though details on form factors, time frames, pricing and anything else you WANT to know about it, is under wraps. These are big time names though, leaders in the PC notebook space, and I think their input to the platform is going to be just as valuable as them selling and marketing it. HP is known for enterprise solutions, Lenovo for mass market share, and ASUS for innovative design and integration.
(If you want to see an Android-based representation of performance on a mobile-based Snapdragon 835 processor, check out our launch preview from March.)
Also on the show floor, Qualcomm begins its marketing campaign aimed to show the value that Snapdragon offers to the Windows ecosystem. Today that is exemplified in a form factor difference comparing the circuit board layout of a Snapdragon 835-based notebook and a “typical” competitor machine.
Up top, Qualcomm is showing us the prototype for the Windows 10 Snapdragon 835 Mobile Platform. It has a total area of 50.4 cm2 and just by eyeballing the two images, there is a clear difference in scope. The second image shows only what Qualcomm will call a “competing commercial circuit board” with an area of 98.1 cm2. That is a decrease in PCB space of 48% (advantage Qualcomm) and gives OEMs a lot of flexibility in design that they might not have had otherwise. They can use that space to make machines thinner, lighter, include a larger battery, or simply to innovate outside the scope of what we can imagine today.

This afternoon, T-Mobile's ardent CEO John Legere announced the results of the FCC's recent spectrum auction concerning the low-band 600MHz range. In a $7.99 Billion deal, T-Mobile is set to gain 45% of all of the low-band spectrum being auctioned.
T-Mobile is quick to point out that the spectrum they purchased covers 100% of the United States and Puerto Rico, with a nationwide average of 31 MHz of spectrum acquired. Having this wide of a range of spectrum available nationwide will help T-Mobile with their rollout of Carrier Aggregation, on the road to Gigabit-Class LTE and 5G.
This acquisition wasn't without help from the FCC however. In 2014, when the FCC decided to auction off the spectrum that was previously used for broadcast TV, they decided to set aside 30MHz of the available 70MHz specifically for carriers that did not currently have large holdings in low-band spectrum. This means that ATT and Verizon, who both operate large LTE networks in the 700MHz range were excluded from part of the spectrum being auctioned off.
Low-band spectrum in strategically important for LTE rollouts in particular as it can travel further and works better indoors than high-band offerings like Sprint's large available spectrum in the 2.5GHz
While it usually takes a significant amount of time to see the results of newly acquired spectrum, T-Mobile promises significant network expansion by the end of 2017. Legere claims that over 1,000,000 square miles of the newly acquires spectrum will be cleared for use by the FCC by the end of this year, and put into production by T-Mobile. T-Mobile plans to use this spectrum to both expand LTE coverage into new markets as well as strengthening their coverage in existing markets to provide more speed and greater density of coverage.
However, there is one side of the 600MHz equation that is out of the hands of T-Mobile, the user equipment. Currently, there are no shipping LTE radios capable of operating in the 600MHz range. Qualcomm has announced that their in-development X20 LTE modem will work with 600MHz, but we have no timeline as to a possible release of devices with the X20.
Hopefully, we don't have to wait too long for user devices capable of 600MHz LTE operation, it would be a real shame to have a newly expanded T-Mobile network that no one can connect to!
The road to Gigabit-class LTE and subsequently 5G seems to be a fierce one, and we look forward to seeing developments from competing carriers.

Hardware/Software Picks of the Week
In conjunction with Ericsson, Netgear, and Telstra, Qualcomm officially unveiled the first Gigabit LTE ready network. Sydney, Australia is the first city to have this new cellular spec deployed through Telstra. Gigabit LTE, dubbed 4GX by Telstra, offers up to 1Gbps download speeds and 150 Mbps upload speeds with a supported device. Gigabit LTE implementation took partnership between all four companies to become a reality with Ericsson providing the backend hardware and software infrastructure and upgrades, Qualcomm designing its next-gen Snapdragon 835 SoC and Snapdragon X16 modem for Gigabit LTE support, Netgear developing the Nighthawk M1 Mobile router which leverages the Snapdragon 835, and Telstra bringing it all together on its Australian-based cellular network. Qualcomm, Ericsson, and Telstra all see the 4GX implementation as a solid step forward in the path to 5G with 4GX acting as the foundation layer for next-gen 5G networks and providing a fallback, much the same as 3G acted as a fallback for the current 4G LTE cellular networks.

What exactly is meant by Gigabit LTE (or 4GX as Telstra has dubbed the new cellular technology)? Gigabit LTE increases both the download and upload speeds of current generation 4G LTE to 1Gbps download and 150 Mbps upload speeds by leveraging several technologies for optimizing the signal transmission between the consumer device and the cellular network itself. Qualcomm designed the Snapdragon X16 modem to operate on dual 60MHz signals with 4x4 MIMO support or dual 80MHz signals without 4x4 MIMO. Further, they increased the modem's QAM support to 256 (8-bit) instead of the current 64 QAM support (6-bit), enabling 33% more data per stream - an increase of 75 Mbps to 100 Mbps per stream. The X16 modem leverages a total of 10 communication streams for delivery of up to 1 Gbps performance and also offers access to previously inaccessible frequency bands using LAA (License Assisted Access) to leverage increased power and speed needs for Gigabit LTE support.

Qualcomm’s new X16 LTE Modem is the industry's first Gigabit LTE chipset to be announced, achieving speeds of up to 1 Gbps using 4x Carrier Aggregation. The X16 succeeds the recently announced X12 modem, improving on the X12's 3x Carrier Aggregation and moving from LTE CAT 12 to CAT 16 on the downlink, while retaining CAT 13 on the uplink.
"In order to make a Gigabit Class LTE modem a reality, Qualcomm added a suite of enhancements – built on a foundation of commercially-proven Carrier Aggregation technology. The Snapdragon X16 LTE modem employs sophisticated digital signal processing to pack more bits per transmission with 256-QAM, receives data on four antennas through 4x4 MIMO, and supports for up to 4x Carrier Aggregation — all of which come together to achieve unprecedented download speeds."
Gigabit speeds are only possible if multiple data streams are connected to the device simultaneously, and with the new X16 modem such aggregation is performed using LTE-U and LAA.

What does all of this mean? Aggregation is a term you'll see a lot as we progress into the next generation of cellular data technology, and with the X16 Qualcomm is emphasizing carrier over link aggregation. Essentially Carrier Aggregation works by combining the carrier LTE data signal (licensed, high transmit power) with a shorter-range, shared spectrum (unlicensed, low transmit power) LTE signal. When the signals are combined at the device (i.e. your smartphone), significantly better throughput is possible with this larger (aggregated) data ‘pipe’.
Qualcomm lists the four main options for unlicensed LTE deployment as follows:
- LTE-U: Based on 3GPP Rel. 12, LTE-U targets early mobile operators deployments in USA, Korea and India, with coexistence tests defined by LTE-U forum
- LAA: Defined in 3GPP Rel. 13, LAA (Licensed Assisted Access) targets deployments in Europe, Japan, & beyond.
- LWA: Defined in 3GPP Rel. 13, LWA (LTE - Wi-Fi link aggregation) targets deployments where the operators already has carrier Wi-Fi deployments.
- MulteFire: Broadens the LTE ecosystem to new deployment opportunities by operating solely in unlicensed spectrum without a licensed anchor channel
The X16 is also Qualcomm’s first modem to be built on 14nm FinFet process, which Qualcomm says is highly scalable and will enable the company to evolve the modem product line “to address an even wider range of product, all the way down to power-efficient connectivity for IoT devices.”
Qualcomm has already begun sampling the X16, and expects the first commercial products in the second half of 2016.
