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."

At least one expert is predicting that the roll out of 5G mobile service will either be delayed or poorly implemented. Over at The Register Professor William Webb offers his insight as to why this will be. He predicts that the physical upgrading or replacing of existing signal stations from 4G to 5G will be significantly more expensive than the upgrade to 4G was and that a hybrid option will result in an insignificant increase in network speeds. He also suggests that total mobile data usage is starting to plateau and we may not even need this extra bandwidth. That is a contentious claim, with mobile usage seemingly increasing thanks to more and more streaming apps and the ever expanding market of mobile users. Any slowdown in total usage could instead be caused by pricing, many simply can't afford the overage charges incurred by heavy data usage but would gleefully slurp up more the moment their data caps increase.
"THE 5G WIRELESS VISION is flawed because technological advances are insufficient to deliver it, users won't pay extra for the higher data rates and don't need the greater capacity it is expected to provide - and because mobile operators can't afford to implement it anyway."

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.
