Qualcomm has announced their first successful 5G New Radio (NR) connection using their prototype sub-6 GHz prototype system. This announcement was followed by today's news of Qualcomm's collaboration with Ericsson and Vodafone to trial 5G NR in the second half of 2017, as we approach the realization of 5G. New Radio is expected to become the standard for 5G going forward as 3GPP moves to finalize standards with release 15.

"5G NR will make the best use of a wide range of spectrum bands, and utilizing spectrum bands below 6 GHz is critical for achieving ubiquitous coverage and capacity to address the large number of envisioned 5G use cases. Qualcomm Technologies’ sub-6 GHz 5G NR prototype, which was announced and first showcased in June 2016, consists of both base stations and user equipment (UE) and serves as a testbed for verifying 5G NR capabilities in bands below 6 GHz."

Qualcomm first showed their sub-6 Ghz prototype this past summer, and it will be on display this week at MWC. The company states that the system is designed to demonstrate how 5G NR "can be utilized to efficiently achieve multi-gigabit-per-second data rates at significantly lower latency than today’s 4G LTE networks". New Radio, or NR, is a complex topic as it related to a new OFDM-based wireless standard. OFDM refers to "a digital multi-carrier modulation method" in which "a large number of closely spaced orthogonal sub-carrier signals are used to carry data on several parallel data streams or channels". With 3GPP adopting this standard going forward the "NR" name could stick, just as "LTE" (Long Term Evolution) caught on to describe the 4G wireless standard.

Along with this 5G NR news comes the annoucement of the expansion of its X50 modem family, first announced in October, "to include 5G New Radio (NR) multi-mode chipset solutions compliant with the 3GPP-based 5G NR global system", according to Qualcomm. This 'multi-mode' solution provides full 4G/5G compatibility with "2G/3G/4G/5G functionality in a single chip", with the first commercial devices expected in 2019.

"The new members of the Snapdragon X50 5G modem family are designed to support multi-mode 2G/3G/4G/5G functionality in a single chip, providing simultaneous connectivity across both 4G and 5G networks for robust mobility performance. The single chip solution also supports integrated Gigabit LTE capability, which has been pioneered by Qualcomm Technologies, and is an essential pillar for the 5G mobile experience as the high-speed coverage layer that co-exists and interworks with nascent 5G networks. This set of advanced multimode capabilities is designed to provide seamless Gigabit connectivity – a key requirement for next generation, premium smartphones and mobile computing devices."

“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.

Qualcomm Announces Snapdragon X50 5G Modem

Subject: Networking, Mobile | October 17, 2016 - 11:00 PM |
Tagged: Snapdragon X50, snapdragon, qualcomm, modem, mobile, mmWave, LTE, cellular, 5G

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.

Qualcomm Announces X16 Modem Featuring Gigabit LTE

Subject: Mobile | February 12, 2016 - 04:26 PM |
Tagged: X16 modem, qualcomm, mu-mimo, modem, LTE, Gigabit LTE, FinFET, Carrier Aggregation, 14nm

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.

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.
