This SoC has been optimised for device deployments in private, mission-critical infrastructure, and public utility networks, enabling global coverage over land, sea, and air - 450 MHz deployments are expected to grow to the tens of millions.

“450 MHz device deployments are already in millions of devices worldwide and serve critical communications needs in safety and emergency services, as well as remote healthcare facilities, schools, and more,” said John Schlaefer, CEO of GCT. “With this new chipset, GCT is fully ready to support the continued growth of 450 MHz, 410 MHz, and 380 MHz networks worldwide.”

With dual RX and low-band dual TX, GDM7243SL utilizes UL diversity and higher power to maintain connectivity even in challenging conditions, such as underground or remote deep forests that do not have access to traditional terrestrial networks.

GCT’s new dual-core solution offers integrated RAM and optional Flash, allowing customers to create fully integrated devices without requiring an external processor. GDM7243SL’s monolithic baseband and radio features tuning from 380 MHz to 3,800 MHz, with multiple ports available to reduce external RF components.

GDM7243SL is expected to sample to customers in the fourth quarter of this year.
