Mobile World Congress 2017 was all about 5G and getting real. Although there is still much hype in the market, actual trials are underway and companies are getting realistic with what can be rolled out first and the progression of technologies needed to work their way into full 5G deployment. 5G connections are forecast to reach 1.1 B by 2025 according to a study made by MWC2017outsideGSMA with wide deployment expected by 2020. The first 5G application being targeted seems to be fixed wireless access for certain locations. Verizon has the jump on everyone launching more than 10 city trials in the USA by June. This is part of the 5G Technology Forum effort supported by several companies such as Cisco, Ericsson, Intel, LG, Nokia, Qualcomm and Samsung. They will be using 28 and 39 GHz phased array technology in the tests.

Just before the event started, 22 mobile communications companies announced collective support for accelerating the 5G new radio (NR) standardization schedule to enable large-scale trials and deployments as early as 2019. The firms are supporting a proposal for the first phase of the 5G NR specification, to be discussed at the next 3GPP RAN plenary meeting. The companies comprising the consortium are AT&T, British Telecom, Deutsche Telekom, Ericsson, Etisalat Group, Huawei, Intel, KDDI, Korea Telecom, LG Electronics, LG Uplus, NTT DOCOMO, Qualcomm Technologies, SK Telecom, Sprint, Swisscom, Telia Company, Telstra, TIM, Vivo, Vodafone and ZTE. The first 3GPP 5G NR specification will be part of Release 15 and based on the current 3GPP Release 15 timeline, the earliest 5G NR deployments based on standard-compliant 5G NR infrastructure and devices will likely be in 2020. 5G Americas (the industry trade association and voice of 5G and LTE for the Americas) announced the publication of Wireless Technology Evolution Towards 5G: 3GPP Release 13 to Release 15 and Beyond that outlines the progress and evolution of LTE technology and the developing 5G standards. The 5G Americas white paper provides a detailed discussion on the key feature enhancements that were included in 3GPP Rel-13 to Rel-15.

IoTA similar track is being followed with IoT as Low Power Wide Area (LPWA) providers that are developing sensible plans for wide scale deployment. The main question is how the proprietary networks will stack up against standard cellular versions now ready to compete with them. And cost is an issue still being address by the networks and device manufacturers.  Strategy Analytics forecasts that IoT cellular devices will transition from a 4G air interface to 5G through 2025, with shipments of 4G IoT modules peaking within two years. 5G modules will begin shipping in 2019 and outsell 4G modules in 2024. Total shipments will exceed 190 million in 2025. The automotive vertical market will remain the single largest consumer of IoT cellular modules during the forecast period and will significantly increase its market share by 2025.

The connected vehicle was a hot topic at MWC as many automotive manufacturers were present. BMW attended for the first time doing live outside demonstrations of autonomous parking. Telefónica and Ericsson, in partnership with KTH and Idiada, showcased the potential of 5G networks with a demo the used Telefonica’s trial 5G network to drive a car prototyped by KTH at Idiada’s race track in Tarragona, Spain, from remote locations at Fira (in Telefónica and Ericsson’s booths). The demo used 15 GHz signals with narrow beams that follow the car / prototype continuously from the 5G base station in order to ensure the reliability and ultra-low latency required by the whole network that connects the cars with the Fira. There were many other remote and autonomous car demos, too many to mention here.

While all of the talk of MWC 2017 was about 5G and IoT, for Microwave Journal it was the unprecedented level of integration at the device level that was the most interesting. GLOBALFOUNDRIES’ release of 45nm RF SOI; Xilinx 16nm All Programmable RFSoCs; Anokiwave/Ball’s, UCSD/TowerJazz’s, and IBM/Ericsson’s 32 element - 28 GHz phased arrays; IDT’s mmWave dual modem; and Cambridge Consultant’s all digital single chip radio are examples of innovations and technologies that will enable the future of wireless. Only with these high levels of integration and innovative radio architectures will the industry achieve the cost and performance levels needed to realize the 5G and IoT goals in the future.

With the second-generation VST, engineers can simultaneously generate and measure up to 32 LTE carriers, each with 20 MHz of bandwidth, and use the software to specify a variety of carrier spacing schemes. The release of NI-RFmx also features algorithm improvements for reduced measurement time. Engineers performing modulation quality and spectral measurements for wireless technologies such as UMTS/HSPA+ and LTE/LTE-Advanced Pro can experience EVM measurement time reductions of up to 33 percent by installing the latest version of the software.

NI was also partnering with a team of 5G engineers from the Universities of Bristol and Lund and BT to perform field trials of a massive MIMO system at the BT Labs in Adastral Park, Suffolk. The trials were conducted in a large indoor hall mimicking a stadium environment and outdoors within the Adastral Park campus. The team obtained promising results indicating that this technology could offer spectrum efficiency figures in excess of the 100 bits/s/Hz mark (sum rate capacity of about 2 Gbps). The system used a 128 element Massive MIMO system operating at 3.5 GHz. Initial experiments used 12 streams in a single 20 MHz channel to show the real-time transmission and simultaneous reception of ten unique video streams, plus two other spatial channels demonstrating the full richness of spatial multiplexing supported by the system. The system was also shown to support the simultaneous transmission of 24 user streams operating with 64 QAM on the same radio channel with all modems synchronizing over-the-air.

R&SRohde & Schwarz featured a new demonstrator solution that makes use of the R&S TSME ultracompact drive test scanner and R&S ROMES drive test software to enable over-the-air characterization of 5G network coverage. In addition, data gathered by this test solution on the propagation of signals at 28 GHz can be used to determine the optimum position of receiving Customer Premises Equipment (CPE) antennas and also to validate and improve network planning tools. The company also expanded the internal analysis bandwidth of its R&S FSW high-end signal and spectrum analyzer to 1.2 GHz by introducing the new R&S FSW-B1200 option. The 1200 MHz bandwidth enables research and development for next generation mobile standards, especially in the 28 GHz and 39 GHz bands for 5G, as well as characterization of wideband amplifiers for 5G. A setup consisting of an R&S FSW with the R&S FSW-B1200 option in combination with an R&S SMW200A vector signal generator easily performs in-depth amplifier and predistortion measurements. The R&S SMW200A supports signal generation up to 40 GHz with up to 2 GHz bandwidth.

Cambridge Consultants said their wireless technology breakthrough is bringing the vision of ‘smart dust’ a step closer to reality. The key is a radical shift in the cost of the most expensive part of the Bluetooth Smart chips at the heart of every connected IoT device, the radio. Cambridge Consultants has used its all-digital radio technology Pizzicato to dramatically cut the silicon cost to just seven cents – less than a tenth of the current cost. The Pizzicato digital radio transmitter consists of an integrated circuit outputting a single stream of bits, and an antenna – with no conventional radio parts or digital-to-analogue converter. Patented algorithms perform the necessary ultra-fast computations in real time, making it possible for standard digital technology to generate high-frequency radio signals directly. It will be interesting to follow this technology and see if it is realized in product (they are looking for partners to take this to market).

With the integration of high performance ADCs and DACs in an All Programmable SoC, radio and wireless backhaul units can now meet previously unattainable power and form factor requirements, while increasing channel density. Additionally, RFSoC devices allow manufactures to streamline design and development cycles to meet 5G deployment timelines. The integrated 16nm-based RF data conversion technology includes: Direct RF sampling for simplified analog design, greater accuracy, smaller form factor, and lower power; 12-bit ADCs at up to 4GSPS, high channel count, with digital down-conversion; and 14-bit DACs at up to 6.4GSPS, high channel count, with digital up conversion. This could represent a game changing way to addressing massive MIMO and future 5G systems as the complexity and power consumption problems are greatly reduced. We will be covering this design in detail in a future issue.

It was certainly the year of 5G and IoT but more importantly, the unprecedented level of integration and innovative architectures for RF technologies has evloved to enable the future of wireless technology.
