A feature of the GDM7243I chip is its low power which will allow it to be used for tracking devices to connect using the Sigfox wireless IoT network for several years without the need for frequent battery re-charging.
“We’re pleased to be working closely with Sigfox to bring this capability to market and support ultra-long battery life and global coverage for our IoT customers,” said John Schlaefer, CEO of GCT Semiconductor at Sigfox World IoT Expo 2017 in Prague.
GDM7243I based tracking devices operate on the Sigfox network for location tracking but will switch to the cellular network as required.
Hybrid devices can connect to the Sigfox wireless IoT network and operate in low-power mode to send and receive notifications-only.
The Sigfox network can also provide backup connectivity to hybrid devices in case of cellular network coverage limitations, congestion, breakdown, or jamming of security/alarm systems.
