MediaTek targets IoT with narrowband chipset

By Nick Flaherty

Taiwanese chip developer MediaTek has launched the industry's first dual-mode chip to combine GPRS and narrow band IoT (NB-IoT) Release 14 (R14) technology.

The highly power efficient MT2621 chipset brings dual-mode cellular technologies for the INternet of Things (IoT). It 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.

The 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 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 efficient Armv7 processor core 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.
