With out Seizo Onoe, cellphone networks wouldn’t be the supply of world connectivity we all know right this moment. The IEEE life member was instrumental in driving the standardization for 3G and 4G mobile networks.
The first-generation networks that launched within the late Nineteen Seventies and early Eighties had been largely country-specific, designed for making solely home or regional calls. There was no solution to ship textual content messages or different knowledge over 1G networks. And interference from different radio alerts made 1G protection unreliable; there have been loads of dropped calls. Plus, with out encryption, eavesdropping was a persistent drawback.
In 1991 2G networks signaled the fledgling {industry}’s change to digital—which improved safety and broadened the vary of options. Fundamental textual content messages turned doable.
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 customary). An industry-wide, standardized mobile telecommunications infrastructure was wanted.
Onoe answered that decision, serving to to align corporations’ and nations’ infrastructures as 3G networks took form.
For his efforts, Onoe has been awarded the IEEE Jagadish Chandra Bose Medal in Wireless Communications. The medal, bestowed for the primary time this yr, is called for an Indian scientist who pioneered radio and millimeter-wave research.
Onoe is at the moment director of the Telecommunication Standardization Bureau on the International Telecommunication Union.
The medal is designed to commemorate contributions to wireless communications applied sciences with a worldwide influence.
“It’s the highest honor for me,” Onoe says, “particularly as I’m the primary recipient.”
Studying early digital cell 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 University in 1976.
“After all, my mother and father additionally instructed 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 cell radio transmission.
The primitive gear on which he minimize his tooth—repurposed (1.544 megabits per second) fixed-line {hardware} donated by {industry}—despatched out cell radio alerts at data rates that might be akin to these of 3G sometime, foreshadowing the digital cell future.
The controversy behind the 3G customary
Japan’s Nippon Telegraph and Telephone in 1979 launched the world’s first 1G network. 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 alerts mandatory for name setup and different controls over an analog community.
“On the time, NTT’s cell companies was a really small division,” he recollects. Issues actually began altering within the early Nineteen Nineties, he says.
In 1992 the corporate spun off its cell division, Docomo (do communications over the cell community). The title was popularly interpreted as a play on the Japanese phrase dokomo, which suggests in all places.
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 growth, together with work on a speedy cell search algorithm, which proved important for community efficiency. The algorithm lets mobile devices shortly establish the closest base station in a mobile community. And it didn’t depend on different techniques, like GPS, to find the right 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 corporations, and regulators—to start envisioning the infrastructure on which a really international mobile community may very well be constructed.
That meant creating a single customary.
“There have been many, many heated debates all all over the world,” Onoe says.
In keeping with history articles revealed on-line by Ericsson, the debates had been complex and contentious. They concerned entities from inside and out of doors the {industry}, together with telephone producers, cell service suppliers, requirements boards, and authorities officers.
Europe alone was contemplating 5 completely different telecom infrastructures throughout the continent’s quite a few cellular networks, Onoe says, highlighting the divide all over the world. Some corporations and nations supported time-division multiple access (TDMA), which might break up the out there community bandwidth into time slots and assign customers particular slots for transmission. Others had been pushing a distinct entry know-how that’s partly competitive 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 yet one more know-how primarily based on orthogonal frequency division multiple access (OFDMA).
In December 1997 the European Telecommunications Standards Institute met in Madrid. At subject could be who managed the requirements for, on the time, the 3G future.
And that’s when the fur actually flew. The Nordic cell producers Ericsson and Nokia squared off in what had been, in accordance with Ericsson’s account no less than, “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 means into lawsuits years later.
Not one of the requirements into account garnered sufficient votes to move. 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 customary 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 the same entry know-how, CDMA2000—Onoe emerged as a significant participant to assist dealer an settlement, as Japan no less than hedgingly supported the push for W-CDMA.
“I made a decision to step in and be part of the struggle, so to talk,” Onoe says. “Throughout all these nations and distributors and people preventing, it was clear we had been going to need to give you some compromises to lastly agree.”
Onoe helped lead an operators’ harmonization group to do exactly that. It proposed altering the chip fee—the frequency at which the smallest models 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 industrial 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 day-after-day together with weekends.
“I might 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 straightforward for me to do.”
NTT turned the primary firm to launch 3G commercially, in October 2001. The brand new wi-fi customary vastly outstripped 2G’s knowledge charges. In the end, common 2G obtain speeds were about 40 kilobits per second, whereas 3G finally would boast as much as 8 megabits per second. The 2G to 3G change represented a night-and-day distinction in pace, making 3G the primary international customary to allow the primary wave of cell video calls, Internet shopping, online games, and streaming video content material.
4G and telecom’s speedy bandwidth development
Together 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 network. Five times faster than 3G, it unlocked high-definition video streaming, lag-free online gaming, and a brand new vary of cell apps together with FaceTime, Snapchat, and Uber.
Onoe additionally performed a key function within the international 4G standardization course of. On the time, he was Docomo’s managing director of R&D technique. He went on to grow to be the corporate’s chief know-how officer, in addition to an govt vice chairman who served on the board of administrators. When he left the corporate in 2022, he was NTT’s chief standardization technique officer.
That yr 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 remains to be not linked. And customary specs assist, as a result of after they’re adopted broadly, they create economies of scale. Competitors will increase, and the value drops. It’s a optimistic 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 supplies, in addition to possibilities to speak concerning the {industry} with fellow engineers.
He works carefully with IEEE leaders in his present place at ITU. In December the organizations convened the IEEE-ITU Symposium on Achieving Climate Resilience, which goals to form a technology-driven highway 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 international know-how.”
