Qualcomm has announced the Snapdragon X20 LTE modem, their 2nd-generation Gigabit LTE solution built on 10nm FinFET and offering what Qualcomm says are “a number of industry firsts”, which include first to Category 18 (downlink) and first to receive up to 12 spacial LTE data streams simultaneously.
“It is the first commercially announced Gigabit LTE chipset designed to deliver fiber-like LTE Category 18 download speeds of up to 1.2 Gbps, a 20 percent improvement in download speeds over the previous generation. Additionally, it allows support for up to 5x20 MHz downlink Carrier Aggregation (CA) across licensed and unlicensed FDD and TDD radio frequencies, as well as 4x4 MIMO on up to three aggregated LTE carriers. Lastly, it supports integrated Dual SIM Dual VoLTE (DSDV) capability, a first for Snapdragon LTE modems. These leading-edge features of the Snapdragon X20 LTE modem are supported by the first commercially announced single-chip RF transceiver capable of simultaneously receiving up to 12 spatial streams of LTE data.”
Compared the the X16 modem featured in the upcoming Snapdragon 835 SoC, the Snapdragon X20 LTE modem moves from Cat 16 to Cat 18 on the downlink, with support for 5x20 MHz (vs. the X16’s 4x20 MHz) Carrier Aggregation and “can simultaneously receive 12 unique streams of data on as few as three 20 MHz carriers”, with up to 256-QAM and 100 Mbps per stream. Uplink is at the same 2x20 MHz/64-QAM as the X16 modem, for speeds of up to 150 Mbps.
The X20 LTE modem now includes VoLTE for both cards in a dual-SIM implementation:
“The Snapdragon X20 LTE modem also features more advanced dual SIM functionality and, as the first Snapdragon LTE modem to support DSDV, it provides users with the benefits of Ultra HD Voice and other IMS-based services on both SIMs inserted into the device.”
Qualcomm has begun to sample the Snapdragon X20 LTE modem to customers, with the first commercial devices expected 1H 2018.
Full press release after the break.
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 has officially unveiled the development of a new 5G modem with the Snapdragon X50, which targets OEMs and early 5G development. The X50 supports milimeter wave (mmWave) technology initially, and rather than replace existing LTE solutions the X50 is designed to work alongside LTE modems integrated into Snapdragon SoCs, for a seamless handoff between 5G and 4G networks.
"The Snapdragon X50 5G modem will initially support operation in millimeter wave (mmWave) spectrum in the 28GHz band. It will employ Multiple-Input Multiple-Output (MIMO) antenna technology with adaptive beamforming and beam tracking techniques, which facilitates robust and sustained mobile broadband communications in non-line-of-sight (NLOS) environments. With 800 MHz bandwidth support, the Snapdragon X50 5G modem is designed to support peak download speeds of up to 5 gigabits per second.
Designed to be used for multi-mode 4G/5G mobile broadband, as well as fixed wireless broadband devices, the Snapdragon X50 5G modem can be paired with a Qualcomm® Snapdragon™ processor with an integrated Gigabit LTE modem and interwork cohesively via dual-connectivity. Gigabit LTE will become an essential pillar for the 5G mobile experience, as it can provide a wide coverage layer for nascent 5G networks."
Ratification of an official “5G” standard has not taken place, but Qualcomm hopes to position itself at the forefront of its development. The mmWave technology (which is explained in this video) is only one part of the puzzle:
"Work has begun on defining, standardizing and designing the new OFDM-based 5G New Radio (NR) as part of the global 3GPP standard. 5G NR is being designed to support a wide variation of device-types, services and deployments. It is also being designed to get the most out of every bit of spectrum across a wide array of available spectrum bands and regulatory paradigms."
(More information is available on Qualcomm's 5G Technologies page.)
The Snapdragon X50 modem is set to begin sampling to OEMs in the second half of 2017, with the first half of 2018 projected for the first commercial products featuring the new modem.

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 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.
