Dual-band wireless receiver chip for 5 and 60 GHz

14.10.2014

A development team from Mitsubishi Electric Company and Tohoku University has created an integrated circuit that implements the function of a receiver capable of operating in the 5 and 60 GHz bands.

The presented chip was created using Si-CMOS technology. Its purpose is the Dependable Air wireless communication system, developed by Tohoku University engineers. This system is characterized by a combination of high reliability and significant speed.

From wireless communication, first of all, greater reliability and high speed are required. However, millimeter wave radio waves, commonly used for high-speed transmission, only provide a reliable connection over short distances. At the same time, in the 5 GHz band, it is possible to organize communication with more distant objects. In the Dependable Air technology, the developers proposed the use of equipment that can operate in two ranges. Moreover, switching between them in accordance with the situation is imperceptible to the user.

The developers of Mitsubishi Electric started from the available RF chips operating in the 5 and 60 GHz bands. By integrating and using part of the blocks for both ranges, they managed to reduce the chip size by about 30%.

According to Mitsubishi Electric, the company is going to standardize the communication technology proposed by Tohoku University, as a result of which it should be included in IEEE802.11, as well as other specifications.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Microplastics make soil less fertile 14.09.2019

The negative impact of plastic waste on the ocean is already well known. New research shows that this pollutant can also make the soil significantly less fertile.

Scientists from Anglia Ruskin University (UK) found that microplastics retard the growth of worms. Given the role of these animals in saturating the soil with nutrients, any interference with their activities can have a serious negative impact on entire ecosystems and hinder the growth of crops that humans feed on.

Exposure to plastic, commonly found in bottles and bags, caused earthworms to lose 3,1% of their body weight over a 30-day period, according to a new study. During the same period, earthworms in plastic-free soil increased their mass by 5,1%.

This is a concern because worms are "ecosystem engineers": they ingest dead organic matter, improve soil structure, promote drainage, and even prevent erosion. If worms lose mass and stunted, this can seriously damage biodiversity.

Researchers don't yet know the specific reasons why microplastics cause worms to lose weight. Perhaps the reaction of earthworms to plastic can be compared with the same mechanisms in aquatic worms that have previously been studied. In aquatic worms, microplastics cause obstruction and irritation of the digestive tract, making it harder for the animals to absorb nutrients and slowing down their growth.

Any pollution that affects the health of earthworms can negatively affect other aspects of the soil ecosystem, such as plant growth.
