Fujitsu Launches Bluetooth 5.0 Dual Mode Wireless Modules

By Fujitsu

Fujitsu Components America today announced the FWM7BTZ61 series of Bluetooth® Ver. 5.0 (dual mode) wireless radio modules compatible with both Bluetooth Low Energy and legacy Bluetooth Classic BR/EDR, giving designers the flexibility to choose between the two modes with one module.

The fully integrated FWM7BTZ61 series is powered by Cypress Semiconductor’s CYW20819 SoC and features Bluetooth Low Energy profile and Bluetooth Classic (BR/EDR) power class 2 capabilities in a single module. It also supports Bluetooth Ver. 5.0’s signature X2 communication.


Using 24 GHz Doppler Radar Sensors for Noncontact Human Vitals Detection

By Fujitsu

Health and wellness monitoring is a primary way to manage personal health and awareness for a healthy lifestyle. Many wearable activity tracking devices, smart watches, and smartphone applications collect and analyze data from bodily sources. Other types of devices used to monitor vital signs can help the wearer manage health issues but can limit the wearer’s mobility or cause discomfort if worn continuously.

These restrictions have prompted a growing interest in developing noncontact, wireless devices to detect vital signs, especially for people who are unconscious, sleeping, very young, elderly, or infirm. This article explains why 24 GHz Doppler radar sensors are useful for such devices and highlights some of the features suitable for meeting these applications.

Simplifies the design of non-contact movement detection products for Healthcare and Industrial IoT

Fujitsu Components America Inc.

Sunnyvale, CA, January 21, 2020

Fujitsu Components America, Inc. has introduced a 3-channel, 24GHz Doppler radar sensor with a wide speed-detection range and high interference tolerance. The module and evaluation kit facilitates the rapid development and evaluation of various non-contact, movement sensing products even without high-frequency RF electronics expertise. Target applications include human vital sign and fall monitoring, structural and mechanical movement detection, machine maintenance, and more, for the healthcare and industrial markets.

The FWM7RAZ01 supports IF (I/Q) output signals from 1Hz to 1 MHz enabling it to wirelessly detect movement speeds from 6 mm per second to 6 km per second, within a 30-meter range. Although 1 MHz of Doppler Effect is not observable in real-world applications, it is effective for detecting signal interference. To prevent signal overlap, the system can select a different channel and avoid misdetection before it happens.
