The wireless world newsletter Hi4Wireless is a periodic technology in which we provide brief headlines of the latest news of the new wireless technologies and the latest news of modern or related wireless technology that was recently monitored around the world. And today it has a technique to sterilize the masks wirelessly – in the wireless news world.
Logitech keyboard without numbers
The Deutsche Presse-Agentur reported that Logitech launched the new Tenkeyless and small version of the G915 wireless gaming keyboard, and I intend to give up the numbers on the board with the intention of reducing their size. Logitech has also replaced the special G buttons, which are located on the left sidebar of the G915 keyboard. It is known that there are three models in terms of button response, including Linear for a soft response, Tactile for a clear response, and Clicky which has an audible response to buttons.
HP announces two versions of the Omen gaming mouse wireless headset
HP has announced new gaming accessories that include two versions of the Omen gaming mouse and the HP X1000 wireless headset. The new gaming mouse also introduces two levels, the first gaming mouse comes entitled Omen Vector with Omen Radar 3 sensor, which is based on the PixArt PMW3389 sensor at a price of $ 49.99, while the second version comes entitled Omen Vector Essential with 220 IPS tracking, and supports up to 20 million clicks and at 29.99 Dollars, while the HP X1000 headset is available at $ 100.
Sub-6GHz networks with “5G”, and mmWave networks with “+ 5G”
The new Android 11 update showed that the system now includes icons that will be used to indicate whether the phone is connected to a 4G or 5G network. But not as recognized, it became clear that the “Ge5” icon does not express the same fifth-generation networks, but rather, in fact, it expresses LTE Advanced Pro.
Although it promises great speeds up to Gbps3, it is still just a successor to LTE Advanced and not the real 5G networks. Google has decided to launch the designation “5G” on the independent fifth-generation networks that depend on the Sub-6GHz spectrum, while it decided to launch the designation “+ 5G” on the independent fifth-generation networks that use the mmWave spectrum.
New Japanese wireless robot to combat coronavirus
Mira Robotics has developed a wireless robot named Ugo that is dedicated to fighting the shortage of manpower in Japan, and CEO Ken Ken Matsui emphasized that with the continuing threat of Coronavirus Covid-19 to many countries around the world, there is a great demand for robots The Japanese company as an important tool to help combat the outbreak. It has a feature in the remote control or the so-called personal robot is a facility that uses ultraviolet light to kill viruses on the door and surface handles.
A powerful laptop that supports 5G network
Getac today unveiled its new and advanced version of the B360, the ultra-durable laptop. The B360 is designed to be fully compatible with the fifth generation of 5G wireless networks, and it has high computing speed, high brightness, in addition to the highest levels of reliability and durability, representing a portable and highly advanced solution, which excels in its performance in difficult working conditions. It also provided the B360 with the tenth generation of Intel® Core ™ processors.
The world’s first “underwater Wi-Fi” from Saudi Arabia
A team of researchers from King Abdullah University of Science and Technology, in the Kingdom of Saudi Arabia, conducted a study that led to the construction of an underwater radio system called “Aqua-Fi”. The researchers built a prototype of the Aqua-Fi system, using green LED lights and a 520 nm laser. Use both to send data from a small and simple computer to an optical detector connected to another computer, and through the system can send multimedia from pictures and video. During its tests, the team was able to record a maximum data transmission speed of 2.11 Mbps, and an average delay of 1.00 ms between transmission and reception.
100 thousand wireless cameras in the homes of the British permeable
The UK newspaper “Dailymail” reported that the UK Consumer Protection Authority has warned that wireless surveillance cameras designed to give people a sense of safety at home may leave their network open to hackers, due to software defects in devices made by the Chinese company HiChip, as it was found that more Of the 100,000 cameras produced by the company, and used in homes across the UK, it has many security flaws.
While HiChip replied that the company has focused on research and development in IP camera for more than a decade and that we “encrypt all commands and data using AES128 between the camera and the application, above the P2P transport layer so our cameras have very low-security risks about user privacy The final. “
New glove translates gestures to speak in real-time
A group of engineers released a new invention of thin and comfortable sensors built into the hand gloves that track the movement of each of the ten fingers. As in “translation”, it includes two stickers on its face: one located between the eyebrows and one side of the mouth. The data also works on a specific movement that is sent to a special chip about 2.5 cm inside each glove to be sent through it wirelessly to the smartphone, where a special application with artificial intelligence. The result is signs that are converted to real sound at the same time.
Technique to sterilize the masks wirelessly
In the wireless news world, the American University of Michigan has also developed a technology that wirelessly sterilizes respirators in the medical field. With very small wireless sensors that allow instant monitoring of the ideal temperature and humidity in the sterilizers, and they automatically sterilize the masks under a certain value of heat and humidity without damaging them in terms of shape and performance.
Strange wireless signals reaching the ground
Canadian CHIME wireless telescope has discovered a strange source of mysterious cosmic radio signals. Canadian scientists have stated in an article published by Nature that the source of the signals cannot be explained by any valid cosmic and astronomical theory because the signals it generates are repeated after every 16 Earth days.
The journal also quoted Jean-Pien, a physical astronomer, as saying that there are 50 theories describing the nature of cosmic radio signals. But all of them are unable to explain the nature of these mysterious repetitive signals. The astronomer said that these signals are strong short wireless pulses with an alien formation whose source is a great distance from Earth.
CDS 20 wireless display from ViewSonic
ViewSonic, a company that specializes in the field of wireless optics, presented its new and distinctive screen, CDE20, which comes with the quality and clarity of ultra-clear images, at a resolution of 4K 2160p, with high levels of viewing angles and brightness. It is linked to an app that can share remote display content and control the management and organization of content and for all Android / iOS smartphones. It is also estimated to cost about 4,696 US dollars.
Developing a smart algorithm to detect penetration of wireless networks
In research in which the Amman Arab University participated, and researchers have developed an intelligent algorithm that helps increase the efficiency of intrusion detection systems in wireless sensor networks. It is research that improves on one of the Gray Wolf Optimizer AI algorithms. In this research, an improved system for IDS intrusion detection in wireless sensor networks has been proposed using a specifically developed algorithm where the infiltration of wireless sensor networks affects or eliminates the ability of networks to perform their functions.
