Mit Has A New 'smart Wall' That Claims To Improve Wi-fi Signal By Almost 10 Times

No repeaters, several routers or MESH networks. The solution that MIT researchers propose to improve the Wi-Fi signal is to provide the walls with thousands of small, low-power antennas. These smart boards are called RFocus and their creators say they can improve up to 10 times wireless signals such as Wi-Fi. They already have working prototypes.

The researchers from the Laboratory of Computer Science and Artificial Intelligence of MIT have created this new “smart surface” (by giving it a name) which is equipped with thousands of small antennas and software responsible for controlling them. Your mission? Amplify the wireless signal with an intensity of up to almost 10 times on certain occasions.

Each RFocus plate is composed of 3,000 antennas. They are placed on vertical surfaces such as walls and will automatically reflect or let the signals through improving their intensity. It is, in essence, a Wi-Fi amplifier, but with the advantage of being much cheaper as they explain and with more promising results.

Walls that improve the signal instead of weakening it

RFocus plates are designed to be installed on walls. Once done, they can be configured to act as a mirror or as a lens. That is, depending on whether we want the signal to cross the wall or not. For example, in a wall of the house that faces the exterior, it is more interesting than it acts as a mirror, while in a wall between rooms it is more interesting than it acts as a lens.

Its creators indicate that where it makes more sense to use this product is in homes with many low-power devices such as IoT products or in warehouses and factories with dozens of sensors and devices connected to the same network. As one of the MIT professors explains, it is ideal if you “want to have wireless devices that transmit at the lowest possible power, but give you a good signal.”

It remains to be seen what the real price of these smart boards is if they ever reach the market. As well as the technology used and if it could be emulated by other manufacturers. Anyway, we may see it before in large facilities than in a home, because apart from the investment in the purchase, you also have to modify the walls to insert these plates.

Alternativa de IA al chat GPT

Recently, you may or have used ChatGPT. This chatbot is OpenAI (Artificial intelligence), which allows users to have conversations with AI. ChatGPT has emerged as a new innovation. With ChatGPT it has changed everything from creative writing to coding and even visual content creation.

In this article, we will provide information about popular ChatGPT alternatives that you can try. Whether it’s for text creation, research, coding, and visual creation.

The following are AI alternatives to GPT chat:

1. Google Bard

Google recently released a new feature called Google Bard, which is Google’s version of ChatGPT. Google Bard is an experimental conversational AI service. Bard is powered by Google’s latest PaLM 2 LLM.

You can use Google Bard as a generative AI for searches, creating presentations, creating speech scripts, and several other features. You’ll immediately see quick answers to questions at the top of the search results. Not to mention, you can also upload images to Google Bard.

Google Bard is quite curious, so we tried to make a comparison between ChatGPT vs Google Bard.

So we can conclude that Google Bard has the following features: Image upload, Chat history, Supported by the latest PaLM 2 model, Export to Document, Colab, Coding capabilities, Multilingual model, Implicit Code Execution

2. Microsoft Bing AI

Microsoft Bing AI. The updated search engine is powered by an optimized ChatGPT model, which Microsoft initially referred to as the Prometheus model, after which it was later confirmed as GPT-4.

Bing-ChatGPT is the new Bing also has a Chat mode that pulls in web queries and allows us to ask for contextual information based on those queries. This Bing bot AI search engine recently received a number of new features, including multimodal capabilities, visual answers, improved accuracy, and Bing Image Creator.

Bing even lets users plan trips, get recipes, seek advice, and more, just like ChatGPT.

Key Features of this Bing AI are supported by GPT-4, Supports visual input and output, Connect to the internet, Getting the latest information on any subject, Chat history, and Different chat modes.

3. Perplexity AI

Perplexity AI is another ChatGPT alternative that you can try. What differentiates this from other AIs is that Perplexity AI has an OpenAI API and, thus, performs well with good responsiveness.

If you visit the Perplexity AI website, it has been packaged in a minimalist and easy-to-use way. So it is easy and simple to use. The tool offers ChatGPT-like functionality, including the ability to host conversations and provide a variety of simple responses. However, unlike ChatGPT, Perplexity even cites the sources it uses to answer your questions.

Can AI Technology Replace Human Jobs? This is ChatGPT Answer!

Published

on

ChatGPT is now under threat of being blocked from Germany

Much has been said about AI chatbots such as ChatGPT, Bing AI, and Google Bard, about whether in the future these tools can replace human work or not.

Recently, ChatGPT by OpenAI answered this question in great detail. What’s the answer?

ChatGPT says that AI-based chatbots can automate several jobs such as customer service, data entry, basic information retrieval, and many others.

This could certainly lead to some job shifts, but would not replace human workers directly.

“As an AI language model, I don’t have the ability to automate jobs or replace human workers directly. However, AI-powered chatbots like ChatGPT can affect certain jobs indirectly,” said ChatGPT, quoted from India Today.

“AI chatbots, including ChatGPT, have the potential to automate certain tasks previously performed by humans, potentially resulting in job shifts across several industries. Routine and repetitive tasks, such as customer service, data entry, and basic information retrieval, are more vulnerable to automation through chatbots,” he continued.

However, ChatGPT explains that it can also create new jobs that will benefit humans.

“The development, implementation, and maintenance of AI chatbots require specific skills such as AI programming, natural language processing, and data analysis, which can create new job opportunities in this field,” he explains.

Furthermore, ChatGPT emphasized that it is difficult for AI to replace human work as a whole because AI cannot imitate the natural sense of empathy, critical thinking, and problem-solving that every human has.

On the other hand, Bing AI said that this chatbot was designed to help humans and not harm them.

“Humans have nothing to fear from AI chatbots like ChatGPT because they are designed to help humans, not hurt them. AI chatbots are neither intelligent nor evil. They are only capable of doing what humans are programmed to do. They have no intentions or emotions of their own. They are tools that can assist humans with various tasks such as answering questions, booking meetings, composing emails, and more,” said Bing AI.

Samsung Releases AC WindFree Ultra, Saves Electricity and Can Filter Pollution

Samsung officially introduced its newest AC product in the WindFree Ultra series today, Monday (3/4).

Samsung WindFree Ultra is a smart air conditioner with air purification capabilities that are expected to be able to bring healthy air into the room.

AC SamsungWindFree Ultra is supported by Air Purification PM 1.0 Filter technology which is capable of capturing very fine particles.

Samsung claims that this smart AC is also able to sterilize more than 99% of bacteria.

The Samsung WindFree Ultra filter can be washed and used continuously so users don’t have to pay more for indoor air purification.

This device is also equipped with an indicator light, helping users to know the air quality in the room quickly.

Support Auto Cooling and Fast Cooling

Samsung WindFree Ultra comes with a fast cooling technology called WindFree Cooling.

When the new AC is turned on, the Fast Cooling feature will cool the room quickly. Furthermore, when the desired temperature has been reached, the WindFree Cooling feature is activated to maintain that temperature and provide an ideal comfort level.

When WindFree Cooling is active, cool air is distributed through 23,000 micro-holes in the body of the AC unit, allowing users to move, relax, and rest comfortably without being directly hit by cold winds.

When WindFree Cooling is working, this smart AC will also consume minimal electrical power, up to 77% more efficiently than the Fast Cooling feature.

This technology is also equipped with a Motion Detect Sensor which automatically changes the mode to save electricity when no one is in the room.

Saving electricity

Samsung AC WindFree Ultra already uses the Digital Inverter Boost energy-saving compressor.

This compressor allows the consumer to maintain the desired temperature while reducing energy consumption.

The Digital Inverter Boost compressor dramatically reduces the time it takes for the compressor to reach maximum power after start-up, cooling air 43% faster and reducing energy use by up to 73% compared to conventional air conditioners.

The lowest power consumption point obtained by this device can reach 180 Watts so the Samsung AC WindFree Ultra has received the highest rating, namely 5 stars for CSPF (Cooling Seasonal Performance Factor) Certification.
