With out Seizo Onoe, mobile phone networks wouldn’t be the supply of world connectivity we all know immediately. The IEEE life member was instrumental in driving the standardization for 3G and 4G cellular networks.
The first-generation networks that launched within the late Seventies and early Eighties had been largely country-specific, designed for making solely home or regional calls. There was no strategy to ship textual content messages or different knowledge over 1G networks. And interference from different radio indicators made 1G protection unreliable; there have been loads of dropped calls. Plus, with out encryption, eavesdropping was a persistent downside.
In 1991 2G networks signaled the fledgling {industry}’s swap to digital—which improved safety and broadened the vary of options. Fundamental textual content messages grew to become attainable.
Particular person nations and carriers had constructed their very own telecommunications infrastructures, nevertheless, utilizing completely different applied sciences and protocols (though Europe had established a typical regional commonplace). An industry-wide, standardized mobile telecommunications infrastructure was wanted.
Onoe answered that decision, serving to to align firms’ and nations’ infrastructures as 3G networks took form.
For his efforts, Onoe has been awarded the IEEE Jagadish Chandra Bose Medal in Wi-fi Communications. The medal, bestowed for the primary time this 12 months, is called for an Indian scientist who pioneered radio and millimeter-wave analysis.
Onoe is at the moment director of the Telecommunication Standardization Bureau on the Worldwide Telecommunication Union.
The medal is designed to commemorate contributions to wi-fi communications applied sciences with a world affect.
“It’s the highest honor for me,” Onoe says, “particularly as I’m the primary recipient.”
Studying early digital cellular radio transmission
Onoe grew up in Akashi, in southwestern Japan. He says he was drawn to the “directness” of STEM topics. He majored in engineering when he enrolled at Kyoto College in 1976.
“After all, my mother and father additionally steered engineering as a result of it was extra advantageous for employment,” he says.
He earned a bachelor’s diploma in 1980 and an engineering grasp’s diploma two years later. As a graduate pupil, he labored on early digital cellular radio transmission.
The primitive tools on which he reduce his tooth—repurposed (1.544 megabits per second) fixed-line {hardware} donated by {industry}—despatched out cellular radio indicators at knowledge charges that may be similar to these of 3G sometime, foreshadowing the digital cellular future.
The controversy behind the 3G commonplace
Japan’s Nippon Telegraph and Phone in 1979 launched the world’s first 1G community. In 1982 Onoe joined NTT’s Yokosuka Electrical Communication Laboratory, in Yokosuka Metropolis. Beginning his NTT profession as a researcher, he helped develop the management indicators mandatory for name setup and different controls over an analog community.
“On the time, NTT’s cellular companies was a really small division,” he remembers. Issues actually began altering within the early Nineteen Nineties, he says.
In 1992 the corporate spun off its cellular division, Docomo (do communications over the cellular community). The title was popularly interpreted as a play on the Japanese phrase dokomo, which implies all over the place.
Onoe was transferred to Docomo in 1992, when the corporate was based, and was later promoted to govt engineer and director. NTT reacquired Docomo in 2020.
He contributed to 3G improvement, together with work on a speedy cell search algorithm, which proved crucial for community efficiency. The algorithm lets cellular units shortly determine the closest base station in a mobile community. And it didn’t depend on different techniques, like GPS, to find the proper cell in a community—making the method simpler, quicker, and cheaper.
His most difficult effort all through the Nineteen Nineties, he says, was together with rising digital mobile stakeholders worldwide—together with governments, telecom firms, and regulators—to start envisioning the infrastructure on which a really world mobile community may very well be constructed.
That meant growing a single commonplace.
“There have been many, many heated debates all world wide,” Onoe says.
In keeping with historical past articles printed on-line by Ericsson, the debates had been complicated and contentious. They concerned entities from inside and outdoors the {industry}, together with cellphone producers, cellular service suppliers, requirements boards, and authorities officers.
Europe alone was contemplating 5 completely different telecom infrastructures throughout the continent’s quite a few mobile networks, Onoe says, highlighting the divide world wide. Some firms and nations supported time-division a number of entry (TDMA), which might cut up the out there community bandwidth into time slots and assign customers particular slots for transmission. Others had been pushing a distinct entry expertise that’s partly aggressive with TDMA and partly complementary to it: code-division a number of entry (CDMA), which makes use of distinctive codes to permit a number of customers to share each bandwidth and time.
As if that rising requirements panorama weren’t sophisticated sufficient, Sony championed one more expertise based mostly on orthogonal frequency division a number of entry (OFDMA).
In December 1997 the European Telecommunications Requirements Institute met in Madrid. At difficulty could be who managed the requirements for, on the time, the 3G future.
And that’s when the fur actually flew. The Nordic cellular producers Ericsson and Nokia squared off in what had been, in line with Ericsson’s account a minimum of, “more and more warlike circumstances.” Britain’s prime minister, Tony Blair, who the above account mentioned “regarded Ericsson as a British firm,” took Ericsson’s aspect within the squabbles. Different ETSI disputes aired at that assembly discovered their method into lawsuits years later.
Not one of the requirements into consideration garnered sufficient votes to go. A second vote could be held the next month in Paris—and so the lobbying started anew.
On the Paris assembly in January 1998, the ETSI voted on W-CDMA because the dominant commonplace for the world’s 3G networks. However within the spirit of compromise, the requirements physique additionally allotted a restricted quantity of 3G spectrum to TD-CDMA, a mixture of the time-division and code-division strategies.
Following that, within the last stage of the 3G standardization battle—a debate between wideband CDMA and an analogous entry expertise, CDMA2000—Onoe emerged as a serious participant to assist dealer an settlement, as Japan a minimum of hedgingly supported the push for W-CDMA.
“I made a decision to step in and be a part of the struggle, so to talk,” Onoe says. “Throughout all these nations and distributors and people combating, it was clear we had been going to should give you some compromises to lastly agree.”
Onoe helped lead an operators’ harmonization group to do exactly that. It proposed altering the chip charge—the frequency at which the smallest items of 3G code are transmitted.
With 3G politics addressed, the exhausting 3G engineering work then started in earnest.
“We needed to begin the event of the business system,” Onoe says. “I don’t assume I absolutely appreciated simply how difficult that was going to be.”
From 1999 till 2001, he says, he labored every single day together with weekends.
“I’d begin conferences at midnight, summarize the day’s actions, and plan for the subsequent day,” he says. “It’s exhausting to think about all these years later, however as a younger and excited engineer, it was simple for me to do.”
NTT grew to become the primary firm to launch 3G commercially, in October 2001. The brand new wi-fi commonplace vastly outstripped 2G’s knowledge charges. Finally, common 2G obtain speeds had been about 40 kilobits per second, whereas 3G ultimately would boast as much as 8 megabits per second. The 2G to 3G swap represented a night-and-day distinction in pace, making 3G the primary world commonplace to allow the primary wave of cellular video calls, Web searching, on-line video games, and streaming video content material.
4G and telecom’s speedy bandwidth development
Along with his contributions to 3G secured, Onoe continued to look ahead. In 2009 Ericsson and Sweden’s TeliaSonera launched the world’s first 4G/LTE community. 5 instances quicker than 3G, it unlocked high-definition video streaming, lag-free on-line gaming, and a brand new vary of cellular apps together with FaceTime, Snapchat, and Uber.
Onoe additionally performed a key function within the world 4G standardization course of. On the time, he was Docomo’s managing director of R&D technique. He went on to develop into the corporate’s chief expertise officer, in addition to an govt vp who served on the board of administrators. When he left the corporate in 2022, he was NTT’s chief standardization technique officer.
That 12 months he was elected to his present function: director of the ITU’s Telecommunication Standardization Bureau. He started his four-year time period at the start of 2023.
“The ITU’s basic mission is to attach the unconnected,” he says. “One-third of the world’s inhabitants continues to be not linked. And customary specs assist, as a result of once they’re adopted broadly, they create economies of scale. Competitors will increase, and the value drops. It’s a constructive cycle.”
Collaborating with IEEE
Onoe joined IEEE early in his profession—following firm coverage at NTT encouraging membership. He says he continues to resume his membership as a result of he values the networking alternatives it offers, in addition to possibilities to speak concerning the {industry} with fellow engineers.
He works intently with IEEE leaders in his present place at ITU. In December the organizations convened the IEEE-ITU Symposium on Attaining Local weather Resilience, which goals to form a technology-driven street map to confront the local weather disaster.
“We additionally maintain joint workshops and conferences and share ideas informally,” Onoe says. “As I’ve seen all through my profession, it’s critically essential that requirements our bodies actively collaborate if we hope to advance world expertise.”
