Without Seizo Onoe, cellular telephone networks wouldn’t be the supply of worldwide connectivity we all know as we speak. 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 technique 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 swap to digital—which improved safety and broadened the vary of options. Basic textual content messages turned potential.
Individual nations and carriers had constructed their very own telecommunications infrastructures, nonetheless, utilizing completely different applied sciences and protocols (though Europe had established a standard regional customary). 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 Wireless Communications. The medal, bestowed for the primary time this yr, is known as for an Indian scientist who pioneered radio and millimeter-wave analysis.
Onoe is presently director of the Telecommunication Standardization Bureau on the International Telecommunication Union.
The medal is designed to commemorate contributions to wi-fi communications applied sciences with a world affect.
“It is the highest honor for me,” Onoe says, “especially as I am the first recipient.”
Learning 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 University in 1976.
“Of course, my parents also suggested engineering because it was more 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 scholar, he labored on early digital cellular radio transmission.
The primitive gear on which he minimize his enamel—repurposed (1.544 megabits per second) fixed-line {hardware} donated by {industry}—despatched out cellular radio alerts at knowledge charges that will be akin to these of 3G sometime, foreshadowing the digital cellular future.
The debate behind the 3G customary
Japan’s Nippon Telegraph and Telephone in 1979 launched the world’s first 1G community. In 1982 Onoe joined NTT’s Yokosuka Electrical Communication Laboratory, in Yokosuka City. Starting his NTT profession as a researcher, he helped develop the management alerts mandatory for name setup and different controls over an analog community.
“At the time, NTT’s mobile services was a very small division,” he recollects. Things actually began altering within the early 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 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 improvement, together with work on a fast cell search algorithm, which proved essential for community efficiency. The algorithm lets cellular gadgets shortly determine the closest base station in a mobile community. And it didn’t depend on different programs, like GPS, to find the right cell in a community—making the method simpler, sooner, and cheaper.
His most difficult effort all through the 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 might be constructed.
That meant creating a single customary.
“There were many, many heated debates all around the world,” Onoe says.
According to historical past articles revealed on-line by Ericsson, the debates had been complicated and contentious. They concerned entities from inside and outdoors the {industry}, together with telephone 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 all over the world. Some firms and nations supported time-division a number of entry (TDMA), which might cut up the obtainable community bandwidth into time slots and assign customers particular slots for transmission. Others had been pushing a unique entry know-how 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 difficult sufficient, Sony championed yet one more know-how based mostly on orthogonal frequency division a number of entry (OFDMA).
In December 1997 the European Telecommunications Standards 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, based on Ericsson’s account a minimum of, “increasingly warlike circumstances.” Britain’s prime minister, Tony Blair, who the above account stated “regarded Ericsson as a British company,” took Ericsson’s aspect within the squabbles. Other ETSI disputes aired at that assembly discovered their approach into lawsuits years later.
None of the requirements into account garnered sufficient votes to go. A second vote could be held the next month in Paris—and so the lobbying started anew.
At the Paris assembly in January 1998, the ETSI voted on W-CDMA because the dominant customary for the world’s 3G networks. But within the spirit of compromise, the requirements physique additionally allotted a restricted quantity of 3G spectrum to TD-CDMA, a mix of the time-division and code-division strategies.
Following that, within the ultimate stage of the 3G standardization battle—a debate between wideband CDMA and an identical entry know-how, 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 decided to step in and join the war, so to speak,” Onoe says. “Across all these countries and vendors and individuals fighting, it was clear we were going to have to come up with some compromises to finally agree.”
Onoe helped lead an operators’ harmonization group to just do that. It proposed altering the chip charge—the frequency at which the smallest items of 3G code are transmitted.
With 3G politics addressed, the arduous 3G engineering work then started in earnest.
“We had to start the development of the commercial system,” Onoe says. “I don’t think I fully appreciated just how challenging that was going to be.”
From 1999 till 2001, he says, he labored day-after-day together with weekends.
“I would start meetings at midnight, summarize the day’s activities, and plan for the next day,” he says. “It’s hard to imagine all these years later, but as a young and excited engineer, it was easy for me to do.”
NTT turned the primary firm to launch 3G commercially, in October 2001. The new wi-fi customary vastly outstripped 2G’s knowledge charges. Ultimately, common 2G obtain speeds had been about 40 kilobits per second, whereas 3G finally 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 customary to allow the primary wave of cellular video calls, Internet looking, on-line video games, and streaming video content material.
4G and telecom’s fast bandwidth development
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. Five instances sooner 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. At the time, he was Docomo’s managing director of R&D technique. He went on to change into the corporate’s chief know-how 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 yr he was elected to his present function: director of the ITU’s Telecommunication Standardization Bureau. He started his four-year time period firstly of 2023.
“The ITU’s fundamental mission is to connect the unconnected,” he says. “One-third of the world’s population is still not connected. And common specifications help, because when they’re adopted widely, they create economies of scale. Competition increases, and the price drops. It’s a positive 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 probabilities to speak in regards to 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 Achieving Climate Resilience, which goals to form a technology-driven highway map to confront the local weather disaster.
“We also hold joint workshops and meetings and share thoughts informally,” Onoe says. “As I’ve seen throughout my career, it’s critically important that standards bodies actively collaborate if we hope to advance global technology.”
