A team from the Massachusetts Institute of Technology (MIT) has developed a device that allows you to have a signal to make calls and an Internet connection to make searches or video calls, from anywhere in the world, preventing your cell phone from being subject to interference or interruptions.
The device uses MIMO wireless technology that allows for both input and output of frequencies, helping to detect and prevent interference before it affects the connection of mobile devices.
This advance promises to greatly improve the quality of wireless communications, especially in places where interference is common, such as concerts, places with a large number of electronic devices, or hidden places on the planet.
Wireless signals, such as those sent over WiFi and 5G (mobile data) networks, are subject to interference that can result in reduced connection quality. This MIT device therefore has the ability to handle stronger spatial interference, ensuring superior performance.
The most common reason for no cell phone coverage is the proliferation of wireless devices in recent years.
From mobile phones, which are essential for work and entertainment, to sensors in self-driving vehicles and Internet of Things (IoT) devices like virtual assistants, This entire ecosystem relies on strong and reliable connectivity.
However, the increase in the number of devices sharing the same radio frequency spectrum has caused increased interference, making it more difficult to block unwanted signals.
To meet this challenge, researchers at MIT have created a millimeter-wave MIMO receiver architecture. This solution not only allows detection, but also early blocking of interference, preventing harmful signals from being amplified and affecting the quality of communication.
“The key to this advance lies in a special circuit known as a ‘non-reciprocal phase shifter’,” Negar Reskarimian, a member of the Microsystems Technology Laboratories and the Research Laboratory of Electronics (RLE), told Europa Press.
The difference with other MIMO devices is that conventional devices can be saturated with strong signals coming from different directions.Which hinders the desired communication. The MIT device effectively identifies and eliminates these interferences, greatly improving the user experience.
Additionally, this architecture is compact and low-power, allowing for up to four times more interference blocking than existing devices.
One of the crucial factors of this technology is its adaptability. Users can enable or deactivate this system as needed, which improves the quality of calls and video calls. In a panoramic landscape where mobile communications are vital, this flexibility provides significant added value.
The design is not only efficient in managing interference, but also has an impact on energy efficiency and space saving.
This receiver is adjustable and takes up less space on the device chip.helping to make smartphones more efficient and have longer battery life.
The use of 5G and 6G networks poses an additional challenge in terms of mitigating interference. “The use of 5G and 6G frequencies in new devices requires systems that mitigate interference to improve their performance,” Reskaremian stressed.
Looking to the future, too, MIT has ambitious plans for this technology. The developed MIMO device is expected to be adapted to larger systems and new frequency bands used by 6G devices.
This effort seeks not only to improve smartphone connectivity, but also to improve a wide range of technological applications that are part of the current and future digital environment.
