Cardholder-sized personal safety device

11 July 2016

MCM Electronics' LONEworkr is a personal safety device, developed with u-blox, which tracks people and acts as an SOS device.

LONEworkr is designed to track lone and isolated workers in order to locate them in the event of an emergency.

Very light (75g) and ultra-compact (96 x 71 x 14.4 mm), LONEworkr combines a 3.75G GSM modem solution providing up to six-band HSPA+ and quad-band GSM/EDGE data transmission with a concurrent reception of GPS/QZSS, GLONASS and BeiDou. It can send an alarm and its location to a Monitoring Centre (MC), which will then call the device to verify the alarm and escalate whether the emergency is genuine.

The u-blox professional grade modules embedded in LONEworkr follow the u-blox “nested design” philosophy: to maintain form factor and software continuity. This enables customers to upgrade their products with each new generation of u-blox wireless modules, without having to change the PCB designs. In this case it can simplify a possible later transition to an LTE modem. The easy migration between u-blox products contributes to a maximised investment, simplified logistics and drastically reduced time-to-market.

The u-blox LISA-U200 UMTS/HSPA cellular module and the CAM-M8Q M8 concurrent GNSS antenna module are currently embedded in LONEWorkr. Migration to LTE technology and the addition of short range radio capabilities are planned.
