The announcement of Google Pixel 4 and Google Pixel 4XL smartphones in October 15, 2019 may not be a huge event for the smartphone industry, but for radars based chips – it is a major change. For the first time, a complete radar in chip is embedded into a smartphone allowing new type of applications and 3D gesture control of the device. To achieve this, Goggle went to Europe, to acquire Infineon’s new BGT60TR13C radar chip.
Infineon has developed a 60 GHz radar chip, based ob its earlier version, the 24 GHz BGT24MTR radar chip. Using an integrated antenna system, BGT60TR13C radar chip appears on a very small area (5 x 6.5 mm) coupled with low power consumption. It senses the presence and movement of people and objects with high precision or measures distances and speeds in an angular scan of 120° and distance ranging from few millimeters up to 5 meters. This chip is the base for Google’s Soli technology and has now been integrated for the first time into a smartphone, so that it can also be controlled by gestures.
“This is a revolution in the human-machine-interaction,” said Andreas Urschitz, Division President for Power Management and Multimarket at Infineon Technologies. “At Infineon, we are furthermore working on the fusion of multiple sensors to simplify interaction and increase the usefulness of the devices.” According to Mordor Intelligence report, the radar sensors market was valued at USD 8.6 billion in 2018, and it is expected to reach USD 22 billion by 2024, registering a CAGR of approximately 20%. The main drivers for this market are the rapidly increasing automation, such as autonomous driving and the Industry 4.0. Until now nobody considered smartphones as a driver for this market.
