TV for mobile phones: crazy growth expected

23.05.2006

At CeBIT in Hannover, mobile operators promised to make watching TV on mobile phones easier and cheaper. This should boost demand for cell phone TV services from the current 1 million subscribers to 250 million by 2010.

T-Mobile, part of the largest European telecommunications holding Deutsche Telekom, announced that it will soon begin broadcasting the MTV music channel for mobile subscribers in Germany and Austria. The service will then be made available in the UK.

T-Mobile is currently expanding its cellular networks, especially in Germany, where the company is deploying HSDPA networks with Nokia. It has a data transfer rate of up to 14Mbps, which ensures fast and smooth video loading without delay.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

Bluetooth 5.0 radio modules STMicroelectronics BlueNRG-M2SA and BlueNRG-M2SP 27.08.2020

The new STMicroelectronics BlueNRG-M2SA and BlueNRG-M2SP radio modules are based on the BlueNRG-2 system-on-a-chip and comply with the Bluetooth 5.0 standard. The modules support multiple roles and can act as a Bluetooth master and slave at the same time. The BlueNRG-M2 radio modules are a complete RF platform including an antenna. The Bluetooth Low Energy stack and user application can run on the module.

Modules allow you to create a complete IoT product without deep knowledge in the field of high-frequency device development and significantly reduce the time to bring a new product to market. Applications for the modules include building control devices, industrial process automation, lighting control, medical equipment and security systems.

The BlueNRG-M2 can be powered directly from a pair of AAA batteries or from any 1,7V to 3,6V power source. The BlueNRG-M2 comes in two variants: BlueNRG-M2SA and BlueNRG-M2SP. They have different internal HW configurations that differ in software initialization. The BlueNRG-M2SP module is a simplified version and does not include the 32768 Hz crystal and inductance to operate the internal SMPS power converter.
