MediaTek Launches New Chipset to Accelerate the Growth of NB-IoT

In a recent announcement, MediaTek launched its newest chipset, MT2621, a dual-mode System-on-Chip (SoC) designed for Internet of Things (IoT) applications with both narrow band IoT (NB-IoT) Release 14 (R14) and GSM/GPRS connectivity. The MT2621 chipset is designed to be power-efficient and brings dual-mode cellular technologies for IoT to drive toward lowest power consumption. It reportedly supports the developments of a broad range of connected devices including fitness trackers and other wearables, IoT security sensors, smart meters and various industrial applications.

MT2621 features an integrated design with a complete connectivity platform that allows it to work with current GSM/GPRS as well as NB-IoT networks for IoT coverage and phone call capability. The connectivity features meet the needs of cellular network infrastructure both GSM and future NB-IoT.

It 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 chipset integrates a wideband front-end module that provides support for all ultra-low, low and mid bands across the globe.

At its core, the MT2621 is powered by an 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.
