A revolution in communications technology: using vortex millimeter waves, Chinese scientists transmitted 1 TB of data over a distance of more than 1 km in one second
China has begun work on the next wireless standard, 6G, as 5G networks are just rolling out around the world, according to the South China Morning Post.
The source writes that Chinese scientists have transmitted 1 TB of data over a distance of more than 1 km in one second, which is a record achievement realized by a team led by Professor Zhang Chao from the School of Aerospace Engineering of Tsinghua University.
The researchers achieved this record by using high frequency radio waves known as vortex millimeter waves. It is reported that 6G technology can be used to improve weapons and defense systems. Tests prove that hypersonic weapons can use 6G for target acquisition and communications.
An experimental wireless system has been installed at the Beijing Winter Olympics complex and can simultaneously broadcast more than 10,000 high-definition live broadcasts. Professor Zhang Chao said vortex millimeter waves are unlike anything that has been used in radio communications in the past 100 years.
The professor added that these signals bring “a new dimension to wireless transmission” and signify that China is leading the world in research into potential key technologies for 6G. Current technology uses two-dimensional electromagnetic waves that move up and down to represent information. Vortex millimeter waves have three dimensions, which are compared to the vortex motion of a tornado.
This rotational movement may contain additional information that will increase the communication throughput. The team created a one-of-a-kind transmitter that allows the waves to move in three different modes to transmit additional data. At the same time, a special receiving device was built, capable of decoding a large amount of data in a fraction of a second.
The source said that this is a revolution in communication technology: “The most interesting thing is not only speed. It’s about introducing a new physical dimension that could lead to a whole new world with almost unlimited possibilities.”
The VTB Bank team announced the launch of a new feature in the web version of VTB Online. According to the press service, VTB was the first on the market to introduce the possibility of paying for services using QR codes in an online bank.
Thus, now users will be able to pay for services using a QR code without using the bank’s mobile application. The functionality is available on iOS smartphones through the Safari browser (starting from version 11), and Android smartphones through the Chrome browser (from version 57 and newer). Later, the service will start working on tablets, laptops and desktop PCs.
To pay using a QR code, the user needs to go to VTB Online through a mobile browser and select the appropriate icon in the interface, after which the device’s camera is activated to read the code. The system itself recognizes all the necessary information for payment and automatically fills in the payment order, which the client will need to check and confirm the transfer of funds to the recipient.
Wearables
1.39-inch AMOLED screen, 150 sport modes, GPS, NFC, heart rate and SpO2 sensors, water resistance and 24 days of battery life for $225. Amazfit T-Rex 2 smartwatch introduced
Huami has officially unveiled the T-Rex 2 smartwatch, one of the brand’s most secure models. Thus, the device remains operational at temperatures down to -30 ° C, it can be submerged in water (10ATM, you can swim with the watch). There’s also a built-in compass, barometer, altimeter, and GPS receiver (supporting Beidou, GLONASS, Galileo, and QZSS).
The watch uses a rechargeable battery with a capacity of 500 mAh, the declared autonomy reaches 24 days. The round AMOLED display is characterized by a diameter of 1.39 inches.
Amazfit T-Rex 2 supports 150 sports modes, six-channel optical sensor BioTracker 3.0 PPG of its own design supports heart rate and blood oxygen concentration. Also, the device allows you to determine the frequency of breathing and recognizes atrial fibrillation. Naturally, there are systems for monitoring sleep and stress.
The novelty will go on sale in China on May 31 at a price of $225. The color options for Amazfit T-Rex 2 are black and green.
Gaming
Sony will not let you enjoy the old games to the fullest. PS3 projects within PS Plus will be released without add-ons
As part of the updated subscription service Sony PS Plus will be available, including projects for PS3. But due to the very specific architecture of the processor of this console, the games will be available in the cloud service.
And now it became known that such games, unfortunately, will not support add-ons. DLC may someday be added, but at first you definitely shouldn’t expect them.
For example, Asura’s Wrath, Castlevania: Lords of Shadow 2, Crash Commando, Enslaved: Odyssey to the West and a number of other games received various kinds of add-ons at one time, for some projects there were a lot of such DLCs. But within the framework of PS Plus, it will not be possible to try them out. The source also publishes a list of PS3 games, but we published them a week ago, when Sony itself did this.
As a reminder, today we also learned that some classic games will work even worse on the new consoles than on the original PlayStation.
