Computers

A CES it is often an important stage for the PC industry, and 2021 was no different. Starting at the base: the processors. AMD introduced the Ryzen 5000 family, with chipsets aimed at notebooks that proved to be quite popular among the manufacturers that announced laptops during the fair.

The company unveiled multi-line chips within the 5000 series, including Ryzen 3, 5, 7 and 9 categories (which compete with Intel's i3, i5, i7 and i9). The chips belong to the U family, which will be made available for ultraportable notebooks, while the H models will be destined for the toughest laptops, aimed at the gamer audience and demanding tasks, such as video editing.

On the other side of the dispute, the highlight of Intel was the revelation of the Alder Lake architecture, which should start to be incorporated into the company's processors in the second half. The technology aims to bring the x86 closer to Arm, which begins to threaten Intel's reign in computers after fully controlling the cell phone market. With that, Intel mimics Arm's BIG.little format, with heterogeneous cores; a part of them is geared towards rough processing and heavy duty, and the other part is for lighter activities, providing energy savings, which is especially important in laptops.

Speaking of laptops, the fair featured several new notebooks from manufacturers such as Asus, Acer, Razer, Lenovo for all types of audiences. Perhaps the most amazing product in the category was the ROG Flow X13, from Asus, which is an unprecedented hybrid gaming notebook, with a hinge that rotates 360 ° and allows use in multiple positions. It is also accompanied by an external case with a GPU RTX 3080, which makes it even more unique.

Cell Phones

CES is not usually a fair focused on mobile technology, but 2021 was a little different. Two of the largest technology companies on the planet presented smartphones that hit the market this year: Korean rivals LG and Samsung drew attention throughout the week with their devices.

LG stood out with a new cell phone concept, which uses the roll-up screen technology that the company has demonstrated over several CES. Called the LG Rollable, the device has a mechanism that causes the display to expand and retract, taking on a conventional tablet or smartphone format depending on the user's preference. The solution is a response to the foldable screen phones that have started to appear in recent years.

The device is expected to hit the market in 2021, with no date or price estimate.

In the meantime, Samsung has put its traditions aside and announced the family of top-of-the-line Galaxy S21 phones, which were typically introduced between late February and early March.

The devices have a lot in common with last year's models, with a more significant aesthetic difference in the camera module; there is also a focus on new camera features. However, the device was marked by what is not present: the company decided to remove the microSD card slot from the cell phone, in addition to the charger that is not offered in the box, just as Apple did with the new iPhones.

Cars

Automotive technology always has a captive space at CES and, even without a pavilion for demonstrating new features, companies were present throughout the week with a series of new features.

Mercedes-Benz presented at the CES 2021 aa MBUX Hyperscreen, from Mercedes-Benz, a 141 cm panel that covers the panel from end to end. In it, the driver finds the instrument panel, the entertainment system and the navigation screen. For the passenger, a separate screen. The system uses an eight-core CPU and has 24GB of RAM. Everything is also connected by artificial intelligence, allowing you to even talk to the system by voice.

Meanwhile, Panasonic has developed an augmented reality solution that projects information into the driver's line of sight to allow him to drive guided by GPS without having to take his eyes off the road. The idea is to reduce distractions and keep you more informed and engaged in the task of driving.

Unfortunately, the system is still a prototype, with no expected arrival on the market, but with great expectations for the future.

Covid

Unfortunately, CES 2021 was held virtually for a very obvious reason: Covid-19. The world is not normal, and the technology industry understood that the topic deserved great attention during the fair. There was no shortage of products that tried to minimize the risk of spreading the virus or to try to identify an infection early.

Nothing is as symbolic in this respect as the Razer colored LED mask. The transparent N95 respirator has active ventilation and replaceable filters and also amplifies the voice to prevent the mask from hindering communication.

There was also no lack of equipment to sterilize environments, with an emphasis on an LG robot that moves around the room firing ultraviolet rays to decontaminate surfaces. As Covid-19's aerial transmission has shown itself to be increasingly significant, countless devices for filtering the air and measuring its quality were also presented to try to eliminate this vector.

One of the outstanding purifiers at the fair is the Luft Duo, which filters the air and reduces the time that the coronavirus can remain in the air, covering an area of ​​22 square meters. According to LUFTQI, the device's manufacturer, it reduces the air time of the Sars-Cov-2 to one hour, instead of 21 hours without air filtration. The equipment also stands out for not needing the purchase of new filters or maintenance, using nanotechnology to remove bacteria and viruses from the air.

Robotics

Few things scream "future" like robots, which is why they always gain space at CES. Samsung did not skimp on its home robotics ideas, notably the Bot Handy, which uses artificial intelligence and a mechanical arm to perform manual tasks for the user, such as helping to organize the house or putting dirty dishes to wash.

Samsung also introduced two other robots. Bot Care is a personal assistant that uses artificial intelligence to recognize patterns of behavior to offer suggestions and support the user's daily life. Two of the examples of functionality presented were to provide reminders for the person to get up from his chair regularly to stretch his body and warn about a video conference that is about to start, bringing a tablet to the user to make the call. JetBot AI + is a robot vacuum cleaner that uses artificial intelligence to navigate the residence and recognize delicate objects, such as vases, to maintain a safe distance. Equipped with a camera, it also allows you to monitor the house from a distance and interact with other connected devices.

CES robots do not live only on utilities. In this CES 2021, the highlight goes to Moflin, from the Japanese Vanguard Industries. It's a pet that even won the fair's innovation award this year.

According to the company, Moflin has emotional abilities and the ability to learn that evolve as in a living animal. Vanguard says that the robot knows how to differentiate the people who interact with it and uses different movements and sounds for each individual.

In addition to Moflin, another pet robot was successful at CES 2021: Petit Qoobo, which is an animated cushion with a tail that tries to replicate the experience of petting a cat, producing a reaction when it receives affection. The model is slightly smaller than the original Qooboo, revealed at CES 2020.

Wi-Fi

Routers also did not do badly during CES 2021. Companies took advantage of the event to take Wi-Fi technology forward, bringing to the market the first wave of devices prepared for Wi-Fi 6E, which brings a new frequency to the standard after twenty years and a much broader spectrum, dramatically reducing the risk of interference, producing less data loss and contributing to better quality connections.

TP-Link demonstrated the Archer AX96 and Archer AX206, both with Wi-Fi 6E, the former reaching maximum speeds of 7.800 Mbps, while the latter breaks the 10 Gbps mark.

The company also unveiled new mesh routers, which allow it to expand Wi-Fi coverage in a home by creating a network of interconnected equipment, Deco X96 and Deco X76 Plus. The problem with these devices is that they use the 6 GHz frequency to communicate with each other, so if the user has a mobile phone (or any other device) compatible with Wi-Fi 6E, they will not be able to take advantage of the technology and will need to connect it to the old frequencies.

Netgear has revealed the Nighthawk RAXE500, another high-performance router that is the first in the line to use Wi-Fi 6E. With its three frequencies, it will be able to support maximum speeds of up to 10,8 Gbps, with the suggested price of $ 600.

 TVs

CES is the TV fair, there is no way to disassociate one thing from the other. Among the highlights of LG at CES 2021 is a transparent TV prototype with panel OLED 55 inches. The screen's 40% transparency allows you to see through it even when it's on. Until now, the brand's transparent screens were only 10% translucent.

Meanwhile, Samsung has renewed its lifestyle line, with a new thinner version of The Frame, the TV that disguises itself as a frame on the wall and has adopted Mini LED technology in its new TVs, in the Neo QLED line.

CES also marked the introduction of a technology that is, in practice, new to the conventional TV market: MicroLED, which is Samsung's answer to OLED, with self-illuminating pixels that light up or go out without the need for bottom. Until then, the technology was present only in the expensive model The Wall, which even depended on customized installation. Now, the company already has less inaccessible (still expensive) models of 110, 99 and 88 inches designed.
