HTA, which is composed of four major European research institutions, including LeTI of France, Fraunhofer of Germany, CSEM of Switzerland and VTT of Finland, held its tenth anniversary. Four research institutes and industry partners showcase Europe's strategic plans and vision for the future development of electronic products.
The Heterogeneous Technology Alliance (HTA), a group of four microelectronics research institutes in Europe, celebrated its 10th anniversary in Brussels. Emmanuel Sabonnadiere, CEO of the French Electronic and Information Technology Laboratory (LeTI), one of the Alliance members, interviewed EE TImes to introduce some research progress from this French technology research institute, including based on its multi-carrier block filtering orthogonal frequency Outdoor Super Wi-Fi communication network with multiplexed (BF-OFDM) waveform technology.
The HTA Alliance is comprised of four major micron and nanotechnology research institutes in Europe, including LeTI in France, Fraunhofer in Germany, CSEM in Switzerland and VTT in Finland. During this week's event, four research institutes, together with several industry partners such as Globalfoundries, Soitec, Nestlé and Murata, demonstrated the strategies and visions of all parties needed to develop electronic products for the future in Europe.
Emmanuel Sabonnadiere said that Leti's short-term strategy (for the next three to five years) is focused on four main areas: advanced data and computing, advanced communications and network security, emerging applications for mobility, and bio-inspired intelligence. Medical device.

He particularly emphasized the 5G device and technology. He said: "As the industry is increasingly focusing on millimeter wave (mmWave) communications, we are working on a device type that will make the front end more digital and closer to the antenna, and also work with a number of industry partners. This also means that FD-SOI technology will be used more in the future."
Sabonnadiere said that he is currently working on a number of 5G projects. “This is important because 5G will become more and more important, so HTA's cooperation is vital to Europe, and we have learned how to work together.â€
Sabonnadiere highlighted the prototype of the 5G system that the company demonstrated at the South Korean 2018 Winter Olympics earlier this year and its success. “This prototype includes buses that travel at 60 kilometers per hour (60km/h), receive data at 5Gbps, and allow people to receive two sports events simultaneously.â€
Sabonnadiere spoke at the event for low-power smart and secure technologies in the ultra-connected era, while demonstrating Leti's outdoor Super Wi-Fi broadband technology, which uses Dynamic Spectrum Access (DSA) technology for the next generation of wireless networks. The road creates a flexible solution based on patented scalable waveforms.
He said: "Wireless communications below 6 GHz face the dilemma of spectrum tightening: lack of sufficient wireless spectrum to support consumer devices, leading to far-reaching impact on the future. Outdoor Super Wi-Fi is targeted by maritime communications and rural broadband This problem overcomes the inherent shortcomings of traditional 4G and Wi-Fi technologies, providing robustness, versatility and flexibility against interference."
Leti's research provides a new BF-OFDM multi-carrier waveform for the air interface, meeting the various requirements of the unified physical layer in the same system bandwidth. Last year, the company also conducted field trials of the technology, pointing out that the technology addresses various shortcomings inherent in actual OFDM waveforms (Wi-Fi/LTE) and is backward compatible with existing receivers.
Through the use of BF-OFDM outdoor Super Wi-Fi, Leti demonstrated the use of non-continuous channels for rural broadband content transmission within 20 km. The Air-to-Air (OTA) Leti test platform is based on FPGAs, ARM processors and flexible RF front ends to demonstrate broadband transmission. Leti also used the same set of equipment for field testing of 5G radios. In addition to the need for efficient wireless connectivity in rural areas, this technology is also ideal for low-cost maritime wireless networks. The waveform also removes the limitations of spectrum sharing, such as white space in the television and authorized shared access in the public broadband radio service.
Sabonnadiere also mentioned that the NetEase Entity System (CPS) and bio-inspired devices are the focus areas of Leti's focus. He said: "We are developing the capabilities of actuators, sensors and edge processing for the NetEase physical system so that it does not have to go to the cloud."
As for bio-inspired devices, he said that Leti is working on some brain computing plans and concepts that mimic organs such as the pancreas.
One of HTA's activities this week is the application of quantum sensors in biomedical imaging, especially quantum magnetometers, which will help reduce the cost of magnetoencephalography (MEG) devices while improving patient diagnosis and treatment.
Sabonnadiere said: "This demonstration shows that the first magnetometer operating at ambient temperature is sensitive enough to provide instant images of brain and heart current cycling for medical diagnosis. MEG sensors can cost MEG scans Reduce at least one-fifth while improving the diagnosis of epilepsy and guiding the surgeon during brain surgery. It will reduce the cost of magnetoencephalography technology from 2.7 million euros to 400,000 euros (equivalent to less than $3.3 million) About $500,000)."
Although Sabonnadiere focuses on Leti's research, it also emphasizes the importance of collaboration within the HTA and the wider academic network worldwide. He said: "We are currently working with Stanford University to optimize various architectures, develop microfluidics and nanofluidics with the Massachusetts Institute of Technology (MIT), and work with ShanghaiTech University. Developed SOI in China and also collaborated with French INRIA to develop software."
