Taiwan-based semiconductor company MediaTek announced its Internet of Things (IoT) chipset MT2621 for applications with both narrow band IoT (NB-IoT) Release 14 (R14) and GSM/GPRS connectivity.

The power efficient MT2621 chipset brings dual-mode cellular technologies for IoT, and ensures lowest power consumption. MediaTek said it will target makers of connected devices including fitness trackers and other wearables, IoT security sensors, smart meters and various industrial applications.

MT2621 IoT chipset works with current GSM/GPRS as well as NB-IoT networks for IoT coverage and phone call capability. MT2621 chipset’s connectivity features meet the needs of cellular network infrastructure both GSM and future NB-IoT.

MediaTek said the new MT2621 requires only a single SIM and antenna to cover both cellular networks, with dual standby functionality (SSDS). This allows a single UICC and mobile number for both networks, even while operating simultaneously, resulting in a cost-efficient, simplified design that enables manufacturers to bring their devices to market faster.

The MT2621 is powered by Armv7 MCU paired with internal Flash and PSRAM. The chipset supports sight and sound interfaces for peripherals, and comes with built-in Bluetooth 4.2 for connecting to other devices nearby.
