Qualcomm 9205 LTE modem – low power will go a long distance
Qualcomm´s 9205 LTE modem is designed for Internet of Things devices that send small amounts of information infrequently over long distances without depleting battery power too quickly. The modem supports LTE-M and NB-IoT networks, which are capable of tapping into the same LTE technology used by 4G. It also allows electronic devices to connect to second generation, or 2G, cellular networks.
The modem is around 50 percent smaller – approximately the size of a dime – and 40 percent lower cost than its current Internet of Things chip, the MDM9206. The idle power consumption has also been lowered by 70 percent. Qualcomm is targeting tiny battery-powered devices that have to remain functional for years without recharging.
Since these cellular networks are thousands of times slower than current 4G networks, companies that want to connect Internet of Things devices can do so more economically. More than 50 networks globally had added support for LTE-M and NB-IoT standards, according to Qualcomm. While LTE-M network use is expanding in the United States, the use of NB-IoT networks has grown in other regions, including Europe and Japan.
Qualcomm 9205 LTE modem technology highlights
- Global multimode LTE IoT modem and connectivity: Support for both 3GPP release 14 Category M1 and NB2 for operation with networks using any of these LTE IoT modes, as well as 2G/E-GPRS to allow for connectivity in areas where LTE IoT is not yet deployed. Category M1 mode also supports voice for applications such as monitored security panels, and mobility for applications such as asset trackers.
- RF transceiver with fully integrated front-end: The Qualcomm 9205 LTE modem features an RF transceiver with extended bandwidth support from 450 MHz to 2100 MHz. It also integrates a comprehensive RF front-end, a commercial first in the cellular IoT space, which is designed to greatly simplify the design and certification of products using the new modem, and therefore accelerate time to commercialisation.
- Advanced battery life management: To maximise battery life, the modem couples ultra-low system-level cut-off voltage with provisions for adapting power usage according to the state of charge of the battery.
- Applications processor: Arm Cortex A7 up to 800MHz with support for ThreadX and AliOS Things real-time operating systems. The integrated applications processor avoids the need for an external microcontroller to improve cost-efficiency, and device security.
- Geolocation: Integrated global positioning support for Global Navigation Satellite Systems (GNSS) including GPS, Beidou, Glonass, and Galileo. The Qualcomm 9205 LTE modem enables design flexibility allowing for the use of either a shared GNSS/LTE antenna or a dedicated one.
- Hardware-based security: Secure boot from hardware root-of-trust, Qualcomm® Trusted Execution Environment, hardware cryptography, storage, and debug security.
- LTE IoT Software Development Kit (SDK): Designed to support developers in running custom software on the integrated applications processor, as well as to provide them access to additional capabilities of the Qualcomm 9205 LTE modem, such as geolocation. The SDK offers pre-integrated support for many cloud platforms, including Alibaba Cloud Link One, China Mobile OneNET, DTSTON DTCloud, Ericsson IoT Accelerator, Gizwits and Verizon ThingSpace, and it also allows developers to extend this integration further and develop support for other major IoT cloud providers.
