Telecom Pioneer Seeso Ono honored

Without Seeso onoCellular phone network will not be a source of global connectivity that we know today. The IEEE life member played an important role in running standardization for 3G and 4G mobile networks.

First generation network It was launched in the late 1970s and early in the 1980s, which was largely country-specific, designed to make domestic or regional calls only. There was no way to send text messages or other data on 1G network. And intervention from other radio signals made 1G coverage incredible; There were many fallen calls. In addition, without encryption, evsdroping was a frequent problem.

In 1991, the 2G network indicated the switch to the flooding industry for digital – which improved security and made the boundary of facilities wider. Basic text messages became possible.

Individual countries and carriers built their own telecom infrastructure, however, using various technologies and protocols (although Europe established a common regional standard). An industry-wide, standardized cellular telecom infrastructure was required.

Ono responded to the call that helps align the infrastructure of companies and countries as a 3G network.

For his efforts, Ono has been honored IEEE Jagdish Chandra Bose medal in wireless communicationFor the first time this year medal medal has been nominated for an Indian scientist. Leading radio and millimeter-wave research,

Ono is currently director Telecommunication bureau But International Telecom Association,

The medal is designed to contribute to wireless communications technologies with a global impact.

“This is the highest honor for me,” Ono says, “especially when I am the first recipient.”

Learning initial digital mobile radio transmission

Ono grew up in the sky in South -West Japan. He says that he was ready for the “directness” of stem subjects. When he enrolled, he studied in engineering Kyoto university In 1976.

“Of course, my parents also suggested engineering because it was more beneficial for employment,” he says.

He earned a bachelor’s degree in 1980 and two years later engineering master’s degree. As a graduate student, he worked on the early digital mobile radio transmission.

Primitive equipment, on which he cut off his teeth–fixed-line hardware (1.544 megabits per second)-mobile radio signal at dated rates that will be comparable to people of 3G, who are rehearsing digital mobile future.

Debate behind 3G standard

Japan Nippon Telegraph & Telephone Launched in 1979 World’s first 1G networkIn 1982, NTT’s Yokosuka Electrical Communication attended Laboratory in Okosuka City. Starting his NTT career as a researcher, he helped develop the necessary control signals on an analog network for call setup and other controls.

“At that time, NTT’s mobile services were a very small division,” he remembers. Things actually changed in the early 1990s, they say.

In 1992 the company shut down its mobile division, Domo (Communicate on mobile networks). The name was popularly interpreted as a drama on the Japanese word DomoMeaning Everywhere,

Ono was transferred to Docomo in 1992, when the company was established, and was later promoted as Executive Engineer and Director. NTT resumed Docomo in 2020.

He contributed to 3G development, including work on a rapid cell search algorithm, which proved to be important for network performance. The algorithm allows mobile devices to quickly identify the nearest base station in a cellular network. And it did not rely on other systems like GPS, to detect the right cell in a network – makes the process easier, faster and less expensive.

His most challenging attempt in the 1990s, he says, emerging digital cellular stakeholders around the world were included – including governments, telecom companies and regulators – to begin to imagine the infrastructure, which could actually be created a global cellular network.

This meant to develop the same standard.

Ono says, “There were many, many hot debates around the world.”

As History article Published online by EricssonThere were debates Complex and controversialThey include institutions from inside and outside the industry, including phone manufacturer, mobile service providers, standard boards and government officials.

In many cellular networks in the continent of Europe alone, five different telecom infrastructure was considering, saying ono, highlighting the division around the world. Supported some companies and countries Time-Division Multiple Access (TDMA), which will divide the available network bandwidth into time slots and assign specific slots to users for transmission. The others were carrying forward a different access technique Partially competitive and partially complemented with TDMA: Code-Division Multiple Access (CDMA), which uses unique code to allow many users to share both bandwidth and time.

As if the emerging standard landscapes were not complex enough, Sony So far based on another technique Orthogonal frequency division multiple access (Ofdma).

In December 1997 European Telecom Standards Institute Meet in Madrid. On this issue, those who control standards for that time, 3g future,

And that is when Fur actually flew. According to what Nordic mobile manufacturer Ericsson and Nokia did Ericsson account At least, “rapid war -like circumstances.” British Prime Minister, Tony BlairThe above account said, “Ericsson is considered as a British company,” Ericsson’s side moved to the squabbles. Other ETSI disputes broadcast in that meeting found their way Case after years,

No standards under consideration gave enough votes to pass. A second vote will be held in Paris next month – and so lobbying started afresh.

At the Paris meeting in January 1998, ETSI voted as the major standard for the world’s 3G network on W-CDMA. But in the sense of compromise, the body of standards also allocated a limited amount of 3G spectrum for TD-CDMA, which is a combination of time-development and code-division methods.

Subsequently, in the final stages of the 3G standardization battle – a debate between the wideband CDMA and a similar access technology, the CDMA 2000 -ono emerged as a leading player to help the Broker to help the Broker in an agreement, as an agreement, at least as Japan Hedgling Supported push to W-CDMA.

Ono says, “I decided to step into war and join it, so to speak.” “Those fighting all these countries and vendors and individuals, it was clear that we were going to make some compromises to agree in the end.”

Ono helped lead to the harmony group of an operators. It proposed to change the chip rate – the frequency on which the smallest units of the 3G code are broadcast.

With 3G politics, hard 3G engineering work then began in Bayana.

“We had to start developing the commercial system,” says Ono. “I don’t think I fully appreciated how challenging it was.”

From 1999 to 2001, he says, he worked every day including weekends.

“I will start meetings at midnight, summarize day activities, and plan for the next day,” they say. “It is difficult to imagine all these years, but as a young and excited engineer, it was easy for me to do.”

NTT became the first company Launch 3G commerciallyIn October 2001. The new wireless standard extended 2G data rates ahead. Finally, average 2g download The speed was about 40 kg per secondWhile 3G will eventually be proud to 8 MegaBits per second. The 3G switch from 2G represented a night and day difference in speed, making mobile video calls, internet browsing, online games and the first global standard to enable the first wave of streaming video content.

Rapid bandwidth growth of 4G and telecom

With his contribution to 3G, Ono looked forward. In 2009 Ericsson and Teliassenara of Sweden launched The world’s first 4G/LTE network. Five times faster From 3G, it unlocked a new range of high-quality video streaming, leg-free online gaming and mobile apps Festeime, Snapchat and Uber,

Ono also played an important role in the global 4G standardization process. At that time, he was the managing director of Docomo’s R&D strategy. He became the Chief Technology Officer of the company, as well as an executive vice -president who served in the board of directors. When he left the company in 2022, he was the main standardization strategy officer of NTT.

That year he was elected to his current role: Director of the Telecom Management Bureau of ITU. He started his four -year term in early 2023.

“The fundamental mission of ITU is to add unlike,” they say. “One-third of the world’s population is still not connected. And helps in general specifications, because when they are widely adopted, they manufacture the economies of the scale. The competition increases, and the value falls. It is a positive cycle.”

Cooperate with IEEE

Ono started in IEEE in her career – to face the company’s policy in membership encouraging NTT. He says that he continues to renew his membership as he gives importance to networking opportunities provided by him, as well as the possibility of talking about the industry with fellow engineers.

He works closely with IEEE leaders in his current position in ITU. Organizations called in December IEEEE-unit seminar on attaining climate flexibilityThe purpose of which is to shape a technology-powered road map to face climate crisis.

“We also catch joint workshops and meetings and share ideas informally,” Ono. “As I have seen during my career, it is seriously important that the bodies of standards actively collaborate if we expect to pursue global technology.”
