The FCC bidding was not terribly exciting but the result was numerous companies buying up parts of the spectrum and more importantly to this post, the opening of 3550-3650 MHz band for anyone to use. The 3.5GHz band is already allocated to shipborne navigation and military radar systems, this will be a test of ability of computer systems to moderate interference instead of the blanket ban they have always relied on in the past.
Google is about to test that ability, they will be running a test in several US cities to check the propagation of the signal as well as any possible maritime or military interference from the broadcast. This could be a way to get high speed internet to the curb without requiring fibre optic runs and would also be compatible with LTE, if Google wanted to dip their toes into that market. You can read about the tests and where they will be happening over at Hack a Day.
"In a recently released FCC filing, Google has announced their experimental protocol for testing the new CBRS. This isn’t fast Internet to a lamp pole on the corner of the street yet, but it lays the groundwork for how the CBRS will function, and how well it will perform."

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.

Qualcomm is branching out with its SoCs to the auto industry with its upcoming line of Snapdragon 820 Automotive processors. The planned Snapdragon 820A and 820Am will begin sampling to auto makers and ODMs within the next few months and are aimed at in-car navigation, entertainment, dash displays, HUDs, and safety/driver assist systems.
Sharing a similar pedigree to the mobile-oriented Snapdragon 820, the new automotive series features Qualcomm's custom 64-bit "Kryo" CPU cores, an Adreno 530 GPU, Hexagon 680 DSP capable of processing up to eight car camera sensors, and 802.11ac Wi-Fi and Bluetooth wireless. The 802Am adds a Snapdragon X12 LTE modem which supports a maximum of 600 Mbps down and 150 Mbps upload speeds. Both chips are built on a 14nm manufacturing process and reportedly utilize a modular package and chip design that would allow auto manufacturers to save money on development costs of new vehicles by allowing upgraded hardware to be used with minimal software changes being necessary. End users aren't going to benefit from the modular nature, but the companies making the "infotainment" systems and those integrating them into new vehicles will.
Qualcomm envisions the 820 Automotive processors driving navigation and entertainment systems as well as being used for digital information displays such as dashboard readouts and windshield HUDs. The chips are also capable of limited driver assist functionality, though they won't be powering a self driving car all on their own yet. They can utilize always on sensors to provide collision alerts and 3D navigation that is aware of relative positioning (it can look for stop signs to assist a GPS which might not be accurate enough to tell you to turn at the correct time). Using between four and eight cameras, the 820Am is able to provide lane departure warnings, front collision warnings, traffic sign recognition, and object detection while backing up using machine learning / computer vision. That last bit is apparently powered by a Qualcomm technology called the Zeroth Machine Intelligency Platform.
There are rumors that Qualcomm will not be pursuing it's custom Kryo CPU cores beyond the Snapdragon 820, though I have my doubts that will happen. The higher margins of the auto industry and opportunity to sell even more chips that can be higher clocked may help to justify the higher R&D in the competitive mobile market. I'm interested to see if these once-mobile SoCs can live up to Qualcomm's promises for future vehicle tech.

The upcoming Snapdragon 820 is shaping up to be a formidable SoC after the disappointing response to the previous flagship, the Snapdragon 810, which was in far fewer devices than expected for reasons still shrouded in mystery and speculation. One of the biggest aspects of the upcoming 820 is Qualcomm’s new X12 modem, which will provide the most advanced LTE connectivity seen to date when the SoC launches. The X12 features CAT 12 LTE downlink speeds for up to 600 Mbps, and CAT 13 on the uplink for up to 150 Mbps.
LTE connectivity isn’t the only new thing here, as we see from this slide there is also tri-band Wi-Fi supporting 2x2 MU-MIMO.
“This is the first publicly announced processor for use in mobile devices to support LTE Category 12 in the downlink and Category 13 in the uplink, providing up to 33 percent and 200 percent improvement over its predecessor’s download and upload speeds, respectively.”
The specifications for this new modem are densely packed:
- Cat 12 (up to 600 Mbps) in the downlink
- Cat 13 (up to 150 Mbps) in the uplink
- Up to 4x4 MIMO on one downlink LTE carrier
- 2x2 MU-MIMO (802.11ac)
- Multi-gigabit 802.11ad
- LTE-U and LTE+Wi-Fi Link Aggregation (LWA)
- Next Gen HD Voice and Video calling over LTE and Wi-Fi
- Call Continuity across Wi-Fi, LTE, 3G, and 2G
- RF front end innovations
- Advanced Closed Loop Antenna Tuner
- Qualcomm RF360™ front end solution with CA
- Wi-Fi/LTE antenna sharing
Rumored phones that could end up running the Snapdragon 820 with this X12 modem include the Samsung Galaxy S7 and around 30 other devices, though final word is of course pending on shipping hardware.

Tagged: snapdragon 410, smartphone, rumor, Moto G, LTE, lollipop, Android
9to5google is reporting specs of the upcoming Moto G refresh, and it looks like the phone will carry over the internals of the current Moto E with a Snapdragon 410 SoC, and add an improved 13MP camera.
The current Moto G has been a favorite for many as a low-cost unlocked option (and one that runs mostly stock Android), and the adoption of the faster SoC with integrated (Cat 4) LTE baseband is a necessary move to update a device that in its current iteration is limited to 3G data speeds. It is interesting that the SoC would only match that of the $149 2015 Moto E (reviewed here), but it makes sense from a financial standpoint if the rumored Moto G is to be sold at or below its current $179 price point.
There is certainly stiff competition in the midrange smartphone market, bolstered considerably by the recently released ASUS Zenfone 2 (reviewed here as well) which starts at $199 unlocked; and with devices like the new Zenfone offering full 1080p screens the rumored choice of the Moto G’s existing 5-inch 720p screen returning in 2015 might be another indication that this new phone will feature a very aggressive price.
The alleged 2015 Moto G photo (image credit: 9to5google)
The phone is also rumored to ship with Android 5.1.1, which would carry on the recent tradition of Motorola phones running the latest versions of Android. All of this is unconfirmed information based on leaks or course, but regardless of its final form more options are always welcome in the $200-and-under unlocked phone space - and this year is shaping up to be a good one for consumers.
Motorola has released an updated version of their low-cost Moto E smartphone for 2015, adding faster hardware and LTE support to an unlocked device with an unsubsidized retail of just $149. In this review we'll examine this new phone to find out if there are any significant limitations given its bargain price.
There has been a trend toward affordability with smartphone pricing that accelerated in 2014 and has continued its pace to start this year. Of course expensive flagships still exist at their $500+ unsubsidized retail prices, but is the advantage of such a device worth the price premium? In most cases a customer in a retail space would be naturally drawn to the more expensive phones on display with their large, sharp screens and thin designs that just look better by comparison. To get the latest and greatest the longstanding $500 - $700 unsubsidized cost of popular smartphones have made 2-year contract pricing a part of life for many, with contract offers and programs allowing users to lease or finance phones positioned as attractive alternatives to the high initial price. And while these high-end options can certainly reward the additional cost, there are rapidly diminishing returns on investment once we venture past the $200 mark with a mobile device. So it’s this bottom $200 of the full-price phone market which is so interesting not just to myself, but to the future of smartphones as they become the commodity devices that the so-called “feature phones” once were.
One of the companies at the forefront of a lower-cost approach to smartphones is Motorola, now independent from Google after Motorola Mobility was sold to Lenovo in October of 2014. A year before the sale Motorola had released a low-cost smartphone called the Moto G, an interesting product which ran stock Android for a fraction of the cost of a Google Play edition or even Nexus device; though it was underpowered with decidedly low-end specs. After a redesign in 2014, however, the 2nd edition Moto G became a much more compelling option, offering a unique combination of low price, respectable hardware, a stock Android experience, and Motorola’s now trademark design language, to a market drowning in bloated MSRPs. There was just one problem: while the 2014 Moto G had solid performance and had (quite importantly) moved larger 5-inch screen with a higher 720x1280 resolution IPS panel, there was still no LTE support. Selling without a contract for just $179 unlocked made the lack of LTE at least understandable, but as carrier technology has matured the prevalence of LTE has made it an essential part of future devices - especially in 2015. Admittedly 3G data speeds are fast enough for many people, but the structure of the modern mobile data plan often leaves that extra speed on the table if one’s device doesn’t support LTE.

With MWC in full swing Intel showed off their mobile silicon to Ryan and to The Tech Report who compiled complete specifications of the Cherry Trail based Atom x5-8300 and 8500 as well as the x7-8700. All three of these chips will have an Intel designed XMM 7260 LTE modem as well as WiFi and NFC connectivity with the X7 also featuring Intel WiGig. You can also expect RealSense, True Key facial recognition and Pro Wireless Display to send secure wireless video to compatible displays for meetings. Check out the full list of stats here.
"Intel says the dual-core Atom x3-C3130 is shipping now, while the quad-core Atom x3-C3230RK is coming later in the first half of the year. The LTE-infused Atom x3-C3440 will follow in the second half. In all, the chipmaker names 19 partners on board with the Atom x3 rollout, including Asus, Compal, Foxconn, Pegatron, Weibu, and Wistron."

SoFIA, Cherry Trail Make Debuts
Mobile World Congress is traditionally dominated by Samsung, Qualcomm, HTC, and others yet Intel continues to make in-roads into the mobile market. Though the company has admittedly lost a lot of money during this growing process, Intel pushes forward with today's announcement of a trio of new processor lines that keep the Atom brand. The Atom x3, the Atom x5, and the Atom x7 will be the company's answer in 2015 for a wide range of products, starting at the sub-$75 phone market and stretching up to ~$400 tablets and all-in-ones.
There are some significant differences in these Atom processors, more than the naming scheme might indicate.
Intel Atom x3 SoFIA Processor
For years now we have questioned Intel's capability to develop a processor that could fit inside the thermal envelope that is required for a smartphone while also offering performance comparable to Qualcomm, MediaTek, and others. It seemed that the x86 architecture was a weight around Intel's ankles rather than a float lifting it up. Intel's answer was the development of SoFIA, (S)mart (o)r (F)eature phone with (I)ntel (A)rchitecture. The project started about 2 years ago leading to product announcements finally reaching us today. SoFIA parts are "designed for budget smartphones; SoFIA is set to give Qualcomm and MediaTek a run for their money in this rapidly growing part of the market."
The SoFIA processors are based on the same Silvermont architecture as the current generation of Atom processors, but they are more tuned for power efficiency. Originally planned to be a dual-core only option, Intel has actually built both dual-core and quad-core variants that will pair with varying modem options to create a combination that best fit target price points and markets. Intel has partnered with RockChip for these designs, even though the architecture is completely IA/x86 based. Production will be done on a 28nm process technology at an unnamed vendor, though you can expect that to mean TSMC. This allows RockChip access to the designs, to help accelerate development, and to release them into the key markets that Intel is targeting.
New Features and Specifications
It is increasingly obvious that in the high end smartphone and tablet market, much like we saw occur over the last several years in the PC space, consumers are becoming more concerned with features and experiences than just raw specifications. There is still plenty to drool over when looking at and talking about 4K screens in the palm of your hand, octa-core processors and mobile SoC GPUs measuring performance in hundreds of GFLOPS, but at the end of the day the vast majority of consumers want something that does something to “wow” them.
As a result, device manufacturers and SoC vendors are shifting priorities for performance, features and how those are presented both the public and to the media. Take this week’s Qualcomm event in San Diego where a team of VPs, PR personnel and engineers walked me through the new Snapdragon 810 processor. Rather than showing slide after slide of comparative performance numbers to the competition, I was shown room after room of demos. Wi-Fi, LTE, 4K capture and playback, gaming capability, thermals, antennae modifications, etc. The goal is showcase the experience of the entire platform – something that Qualcomm has been providing for longer than just about anyone in this business, while educating consumers on the need for balance too.
As a 15-year veteran of the hardware space my first reaction here couldn’t have been scripted any more precisely: a company that doesn’t show performance numbers has something to hide. But I was given time with a reference platform featuring the Snapdragon 810 processor in a tablet form-factor and the results show impressive increases over the 801 and 805 processors from the previous family. Rumors of the chips heat issues seem overblown, but that part will be hard to prove for sure until we get retail hardware in our hands to confirm.
Today’s story will outline the primary feature changes of the Snapdragon 810 SoC, though there was so much detail presented at the event with such a short window of time for writing that I definitely won’t be able to get to it all. I will follow up the gory specification details with performance results compared to a wide array of other tablets and smartphones to provide some context to where 810 stands in the market.

Tagged: CES, smartphone, p90, LTE, Lenovo, Intel, ces 2015, atom z3560
Unveiled today at CES, the Lenovo P90 is the first smartphone to use Intel's latest Atom Z3560 processor and 5-mode XMM 7262 modem. The smartphone pairs the high end hardware with a colorful body that weighs 156g and is a mere 8.5mm thick.
The Lenovo P90 brings Intel back to the Lenovo smartphone family following a year dominated by smartphones powered by MediaTek and Qualcomm SoCs. Unfortunately, like the K900 that came before it, the P90 will not be available in the United States. Now that I've crushed the dreams of some US readers...
On the outside, the P90 looks to be your average roughly rectangular smartphone with curved edges. Lenovo does manage to spice things up a bit by offering it in Lava Red in addition to Pearl White and Onyx Black. A large 5.5" 1920x1080 display dominates the front of the device. A 5 megapixel front facing camera sits above the display and a 13MP camera with flash and optical image stabilization (OIS) sits on the back.
The Lenovo P90 is powered by a 64-bit quad core Intel Atom Z3560 clocked at 1.83 GHz paired with 2GB of RAM and 32GB of internal flash storage. Lenovo is using the Intel XMM 7262 modem for cellular connectivity which is LTE capable and supports data speeds of up to 150 Mbps download and 50 Mbps upload (obviously, dependent on carrier support, congestion, and signal strength, et al). A large 4,000mAh battery powers the P90.
Unlike the Vibe X2 Pro, the Intel-Powered P90 will ship with Android 4.4 KitKat. Obviously, the Atom-powered phone will have to use binary translation for many apps that are not available natively in x86-64, but the Z3560 should be plenty of hardware to handle that overhead even with the alleged 20%-40% performance hit.
The Lenovo P90 will be available in February for $369. It will hit China and Europe but not this side of the pond.
Are you interested in an Intel-powered smartphone? Do you care what the SoC is, or do you just want something with enough oomph to run your applications? I do wish Intel would be more aggressive in getting its SoCs into phones that will be available here, if only for more competition.
