Nokia Bell announced that recently, under the guidance of the Ministry of Industry and Information Technology (MIIT), the IMT-2030 (6G) Advancement Group organized a concept prototype test of key 6G technologies, and Nokia Bell successfully completed the test verification of terahertz communication and pass-through integration. The team will start 6G technology trials in 2022 to evaluate and test potential key 6G technologies. As one of the key members of China IMT-2030 (6G) Promotion Group, Nokia Bell has actively participated and promoted key activities such as research, evaluation and validation of 6G key technologies.

During MWC2023, Qualcomm Technologies announced the launch of its second-generation Snapdragon Automotive 5G modem and RF platform. Qualcomm introduces the second-generation Snapdragon automotive 5G platform with support for satellite communications. As Qualcomm Technologies' automotive modem and RF system, it features high-performance processing and up to 200MHz of network capacity to support reliable and low-latency connectivity for a safe, smart and immersive driving experience. Equipped with the latest 5G technology enhancements, owners can enjoy the comfort and convenience of their car, home and office in the same space.

The "digital divide" will determine the success or failure of businesses. For many companies, turning "data insights" into business value has been an elusive goal; however, the maturation of artificial intelligence (AI) technology will eventually make this possible - companies can distill data information and put it into action.

Variable optical attenuator is an important optical passive device in fiber optic communication, which enables real-time control of the signal by attenuating the transmitted optical power. Simply put, in optical modules, the use of optical attenuators can reduce the bit error rate (BER). In order to achieve BER, optical power needs to be reduced, which requires the use of optical attenuators.

Digital oscilloscope is a general-purpose test instrument, essentially a graphic display device, equivalent to a voltmeter or multimeter with a graphic display, can visually display the signal waveform on the screen over time, and the waveform period, voltage, frequency and other parameters for measurement and analysis, widely used in scientific research, production and other fields, is the engineer design, debugging, maintenance of products when the main test instrument, plays a pivotal role in the test work.

A spectrometer is a scientific instrument that decomposes light of complex composition into spectral lines, consisting of prisms or diffraction gratings, etc. Using a spectrometer, light reflected from the surface of an object can be measured. The seven colors of light in sunlight are the parts that can be divided by the naked eye (visible light), but if the sunlight is broken down by a spectrometer and arranged by wavelength, visible light only accounts for a very small range of the spectrum, and the rest are spectra that cannot be distinguished by the naked eye, such as infrared, microwave, ultraviolet, X-rays, etc.

To meet the rapidly expanding data traffic in today's world of smartphones and mobile devices, data centre network interfaces are moving to the faster 200 GbE, 400 GbE and 800 GbE standards. In this context, communication equipment interconnections have begun to adopt not only PCI Express Gen5, which supports faster speeds of up to 32 Gbit/s, but also multichannel technology.

Recently, China's largest and the world's third largest packaging and testing company Changdian Technology announced that the XDFOI Chiplet process has achieved a breakthrough, and began to gradually enter the stable mass production stage, synchronised with the realization of the international customers 4nm node multi-chip system integration packaging product shipments, the largest package body area of about 1500mm2 system-level packaging.
