Radio-wave ranging sensor

Precision to realize smarter world

We are on the brink of entering a world of home automation where home appliances incorporate IoT functionality and sensors are network-connected for interoperation, and where products are able to incorporate services that identify, interpret, and anticipate human behavior. One example might be a camera that automatically activates whenever someone approaches, and sends an email to family members to let them know this has happened.

To achieve digital transformation (DX) that blends the real and digital worlds, Socionext has developed compact and highly accurate radio-wave ranging sensors that feature low energy consumption and excellent cost/performance. Easy-to-use and offering a high level of sensing performance, these sensors are helping to realize the smart society of the future, with their use for object location dramatically broadening the possibilities of smart home IoT devices.

Product Overview

Socionext has been designing RF CMOS sensors since 2012, leveraging the radar sensing technologies it has accumulated over the years to develop ultra-compact, high-performance radio-wave ranging sensors. Use of these radio-wave ranging sensors is helping to transform the future of IoT, allowing for package miniaturization through reduced RF interference and minimizing overall system costs for customers.

●Benefits

[Reduced interference allows for smaller package size]

While it is standard practice to house multiple antennas inside the LSI package, radio interference between nearby antennas can hamper data transmission, reducing data throughput and degrading performance. As a result, RF circuit design needs to include measures for reducing interference. In its efforts to reduce package size, Socionext is applying its advanced and highly specialized engineering expertise to mitigate the issues of interference between nearby antennas and reflection noise from the package resin.

[Lower overall system costs for customers]

Incorporating multiple antennas in a single chip can be beneficial for obtaining better azimuth resolution in a small form factor. This can also help to free customers from complicated antenna design challenges.
Meanwhile, the selection of a CMOS process allows for the on-chip implementation of complex signal processing functions and the integration of sophisticated algorithms for detecting signal angle of arrival, distance to target, and movement of target. This minimizes the software development required for downstream signal processing by an MCU and reduces MCU performance requirements. These features of Socionext radio-wave ranging sensors reduce system power consumption, cut material costs significantly, and shorten the development time required to bring customer products to market.

●Features

As each product has a built-in distance measurement circuit, you can use it without any knowledge of signal processing.

A wide range of sensing types are available, including intermittent sensing and burst sensing.

We offer a lineup of products with multiple reception channels that enable detection of positional information.
