Qualcomm uses AI to amplify the mobile cellular signal

Thanks to AI modems will be able to improve the performance of 4G and 5G, but it is on the millimeter waves mmWave gain will be most interesting.

If artificial intelligence is often used on smartphones to improve the appearance and quality of photos, it will soon be able to increase the performance of cellular communications and coverage of 5G mobile devices. This is at least a bet of Qualcomm, which claims that the artificial intelligence algorithms integrated into its modems will be able to increase signal coverage and thus expand the range of all radio devices connected to the device, including 4G and 5G equipment. The use of artificial intelligence will be included in the Snapdragon X70 modem, which should be delivered this year to be found in smartphones in 2023.

These announcements were made during the Qualcomm 5G summit, which took place on May 9-11 in San Diego, California. Most of the improvements relate to the technology of short-range high-speed millimeter waves (mmWave). 5G combines two technologies that work in parallel: sub-6 GHz wireless signals that can cover tens of kilometers at speeds of several hundred megabits per second, and powerful but limited mmWave technology that covers only a few tens of meters at speeds more. than one gigabit per second bandwidth. T-Mobile also uses an intermediate band that fills the gap. But most users are interested in the great features of mmWave and its many real-world applications, such as the thousands of people who take photos and videos of an outdoor concert and then share them on social media. However, due to the limited range, Qualcomm and operators want to improve mmWave’s performance. And AI can give the answer.

Improved smartphone / repeater antenna connection

Ignacio Contreras, Qualcomm’s director of product marketing, told reporters that the artificial intelligence finding could expand mmWave’s reach by about 20 percent, although the technique could be used to improve other cellular technologies. In conclusion, Qualcomm teaches the modem what to do before it encounters a real scenario. Mobile phones always communicate using a relay antenna, to which they send context information to optimize data transfer. Thus, a modem that supports artificial intelligence can be fine-tuned before it is put into operation. In the real world, a smartphone modem will transmit not only the current conditions, but also its network status forecasts to improve the performance of all devices in the system. Thanks to mmWave, the smartphone could indicate to the mobile that it would be better to switch to a new beam if it is available.

“Thanks to the artificial intelligence processing integrated into the system model, the device will not only be able to inform about current conditions, but also predict conditions in the next moment,” added Mr. Contreras. At the same conference, which ends today, Qualcomm will also demonstrate standalone mmWave technology. Today, every mmWave deployment requires binding to frequencies below 6 GHz to perform control functions. By freeing millimeter waves from this control, 5G can be used in more applications, including fixed wireless broadband, as offered by T-Mobile. Finally, Qualcomm has announced the launch of a technology called Smart Transmit 3.0, which can intelligently control power when a smartphone downloads data over a network. Smart Transmit 3.0 power management algorithms will now include information sent over Wi-Fi and Bluetooth.
