Ameya360:Ubiik and Realtek Partner on Dedicated NB-IoT Module for 3GPP Band 103

　　Ubiik Inc. has joined forces with Realtek Semiconductor Corp. to develop Nimbus 220, an NB-IoT module based on Realtek RTL9518 chipset, and optimized for operation in Upper 700MHz A Block band. This is an important development for the utility and IoT markets in the United States, as the joint development will allow license holders of Band 103 to fully utilize this prime 1MHz paired spectrum by leveraging advanced features such as non-anchor carriers and Non-IP Data Delivery (NIDD).　　After Select Spectrum and Access Spectrum have announced that the Upper 700MHz A Block is officially designated in 3GPP Release 16 as “NB-IoT Band 103” for 4G and 5G services, Ubiik and Realtek are now partnering on the development of this NB-IoT module allowing Ubiik’s cellular base station goRAN to address current gaps in the North American market for band 103 (787-788MHz uplink and 757-758MHz downlink). With NB-IoT using as little as 180kHz of spectrum, and being able to scale up by utilizing multiple carriers simultaneously, companies who are currently utilizing this band now have the possibility to add standard-compliant NB-IoT to deliver affordable, long-range connectivity to low-power or low-throughput devices.　　“We are excited to collaborate with Realtek in bringing forth Nimbus 220 that supports Band 103,” said Tienhaw Peng, Founder and CEO of Ubiik. “This advanced module, when paired with our Ubiik goRAN base station, offers a cost-efficient 3GPP solution for implementing smart grid, AMI, and other IoT applications within the Upper 700MHz spectrum. At Ubiik, we are dedicated to supporting the 3GPP ecosystem and helping our clients fully leverage the capabilities of their IoT investments.”　　With this partnership, Ubiik aims to expand its reach in the North American market and provide customers with reliable private LTE connectivity. The module, whose embedded processing unit can support ANSI meters and other applications/protocols, will be launched together with goRAN base stations and showcased at Distributech 2023 in San Diego from February 7–9, 2023.

5G Baseband Dialed in at 3GPP

　　The 3GPP announced with a tweet from a meeting in Portugal it finished the first standard for a 5G cellular radio. The effort was on an accelerated path to define a spec before the end of the year for baseband chips that are now on their own accelerated path to market before July.　　The milestone concludes a process that attracted as many as 800 engineers submitting up to 3,000 proposals per meeting.　　“Given operator interest, we’ve been doing everything we can to improve the time from spec freeze to commercialization, it is a race to launch 5G devices…so as decisions were made in meetings, we shared them with the ASIC team implementing hardware — it’s all pipelined to incorporate the final changes,” said John Smee, a vice president of engineering for corporate R&D at Qualcomm.　　Details of the Release 15 physical-layer standard were essentially complete after final work group meetings that concluded Dec. 1. That enabled Qualcomm and Ericsson to announce today they already have tested the final spec in their labs running on handsets and base stations using FPGAs.　　“After Release 14, we had an idea what we were shooting for in terms of a general architecture, but the specifics of slot structures, signaling, channel coding, pilot structures and so on were gelling through 2017,” said Smee.　　The current 3GPP spec enables 5G connections over today’s LTE core networks that carriers are expected to offer as commercial services in 2019. The 3GPP aims to deliver next fall a spec for 5G core networks enabling so-called standalone 5G links.　　“A few thousand nodes of the [LTE-based standard] will be deployed in the U.S. by the end of next year for fixed-wireless access with Ericsson and Nokia in the driver’s seat,” for last-mile access services planned by Verizon and others, said Stephane Teral, an analyst at IHS Markit.　　The standalone version will enable broadband mobile services expected for “commercial launch in Korea in 2019 as well as a massive trial in China — then we’ll get Samsung, Huawei and ZTE on board to shake up the market,” Teral said.　　Another market researcher forecasts a 5G build out won’t return the base station market to growth until 2021 given the decline in LTE build outs.　　In separate announcements over the past year, Intel and Qualcomm discussed their plans for their competing 5G baseband chips for smartphones. Base station OEMs typically design their own ASICs as part of their secret sauce.　　Qualcomm ships about half of the client-side LTE basebands today, followed by Samsung and Mediatek. Intel has been leaping up from far behind in the rankings thanks to its design wins in the latest Apple iPhones, said market watchers at Strategy Analytics.　　The 5G baseband race will be measured in the quality of the implementations as well as their time to the finish line. Vendors will differentiate their chips, in part, by the numbers of global frequency bands and receive/transmit antennas they support as well as their latency, throughput and energy efficiency — especially in their power amplifiers, said Qualcomm’s Smee.　　Looking ahead, Release 16 is expected to enable next-generation modems supporting shared licensed/unlicensed spectrum, ultra-low latency links and a capability for base stations to talk with each other to coordinate their efforts, he said.　　In U.S and Sweden labs earlier this month, Qualcomm and Ericsson tested the Release 15 spec over 3.5 and 28 GHz bands. Nine carriers provided input on or observed the tests including AT&T, NTT Docomo, Orange, SK Telecom, Verizon and Vodafone.　　The effort followed a test late last month at a China Mobile lab using a prototype base station from China’s ZTE. Qualcomm has announced plans to test its prototype baseband with Nokia’s base stations.　　“Over the next few months, we will add functions and get ready for over-the-air trials with operators, taking the technology from the lab to the field,” said Smee.

3GPP Burns Midnight Oil for 5G

　　The race is on to deliver some form of 5G as soon as possible.　　An Intel executive painted a picture of engineers pushing the pedal to the metal to complete an early version of the 5G New Radio (NR) standard by the end of the year. She promised that Intel will have a test system based on its x86 processors and FPGAs as soon as the spec is finished.　　The 3GPP group defining the 5G NR has set a priority of finishing a spec for a non-standalone version by the end of the year. It will extend existing LTE core networks with a 5G NR front end for services such as fixed-wireless access.　　After that work is finished, the radio-access group will turn its attention to drafting a standalone 5G NR spec by September 2018.　　“Right now, NR non-standalone is going fine with lots of motivation, come hell or high water, to declare a standard by the end of December,” said Asha Keddy, an Intel vice president and general manager of its next-generation and standards group. “The teams don’t even break until 10 p.m. on many days, and even then, sometimes they have sessions after dinner.”　　To lighten the load, a plenary meeting of the 3GPP radio-access group next week is expected to streamline the proposed feature set for non-standalone NR. While a baseline of features such as channel coding and subcarrier spacing have been set, some features are behind schedule for being defined, such as MIMO beam management, said Keddy.　　It’s hard to say what features will be in or out at this stage, given that decisions will depend on agreement among carriers. “Some of these are hit-or-miss, like when [Congress] passes a bill,” she said.　　It’s not an easy job, given the wide variety of use cases still being explored for 5G and the time frames involved. “We are talking about writing a standard that will emerge in 2020, peak in 2030, and still be around in 2040 — it’s kind of a responsibility to the future,” she said.　　The difficulty is even greater given carrier pressure. For example, AT&T and Verizon have announced plans to roll out fixed-wireless access services next year based on the non-standalone 5G NR, even though that standard won’t be formally ratified until late next year.　　Companies such as Intel and Qualcomm have been supplying CPU- and FPGA-based systems for use in carrier trials. They have been updating the systems’ software to keep pace with developments in 3GPP and carrier requests.　　For its part, Intel has deployed about 200 units of its 5G test systems to date. They will be used on some of the fixed-wireless access trials with AT&T and Verizon in the U.S., as well as for other use cases in 5G trials with Korea Telecom and NTT Docomo in Japan.　　Some of the systems are testing specialized use cases in vertical markets with widely varied needs, such as automotive, media, and industrial, with companies including GE and Honeywell. The pace of all of the trials is expected to pick up next year once the systems support the 5G non-standalone spec.　　Intel’s first 5G test system was released in February 2016 supporting sub-6-GHz and mm-wave frequencies. It launched a second-generation platform with integrated 4x4 MIMO in August 2016.　　The current system supports bands including 600–900 MHz, 3.3–4.2 GHz, 4.4–4.9 GHz, 5.1–5.9 GHz, 28 GHz, and 39 GHz. It provides data rates up to 10 Gbits/second.　　Keddy would not comment on Intel’s plans for dedicated silicon for 5G either in smartphones or base stations.　　In January, Intel announced that a 5G modem for smartphones made in its 14-nm process will sample in the second half of this year. The announcement came before the decision to split NR into the non-standalone and standalone specs.　　Similarly, archrival Qualcomm announced late last year that its X50 5G modem will sample in 2017. It uses eight 100-MHz channels, a 2x2 MIMO antenna array, adaptive beamforming techniques, and 64 QAM to achieve a 90-dB link budget and works with a separate 28-GHz transceiver and power management chips.

5G Proposals Jam 3GPP Channels

　　5G cellular has a problem with its signal-to-noise ratio, but it’s still expanding and even moving ahead at an accelerated pace.　　The problem is some companies have started measuring their progress by the number of contributions they make to the 3GPP group defining 5G specifications. The practice has gotten so out of hand that some engineers are actually splitting a proposal into multiple papers, forcing some work groups to set a limit of one paper per company per agenda item.　　“Certain companies have been trying to game the system,” said Lorenzo Casaccia, a vice president of technical standards responsible for 3GPP work at Qualcomm.　　“In the last few months, two of most important work groups put a cap on the number of proposals engineers can submit because the chairs got fed up with people splitting contributions,” Casaccia said in an interview.　　Qualcomm is among less than a dozen companies who file the brunt of the technical contributions to 3GPP. Casaccia’s group includes 80 people who regularly attend 3GPP meetings and hundreds who support them with lab designs and simulations.　　The company measures Casaccia’s group not by its 3GPP contributions but by more ambitious goals. For example it has succeeded in its goal to accelerate deployment of 5G with a 3GPP decision announced in March to enable a hybrid LTE/5G service. It also succeeded in convincing 3GPP to enable use of LTE in unlicensed bands.　　“We definitely don’t measure contributions, which are just one tool to achieve these goals,” he said, noting forging alliances as another tool.
