Qualcomm 9205 LTE Modem

The Qualcomm® 9205 LTE modem is our next-generation global multi-mode single chipset connectivity solution and purpose-built to support reliable, optimized cellular connectivity for Internet of Things (IoT) applications such as asset trackers, health monitors, security systems, smart city sensors and smart meters, as well as a range of wearable trackers. Key features of Qualcomm 9205 make it ideal for battery-powered IoT devices to help them operate for nearly 10 years or longer in the field and IoT applications requiring low-power, wide-area connectivity in a small form factor.

Qualcomm 9205 is a product of Qualcomm Technologies, Inc. and/or its subsidiaries.

Global multi-mode, multi-band solution

The Qualcomm 9205 LTE modem is a multi-band, multi-mode solution with extended RF frequency support from 450MHz to 2.1GHz to enable more than 23 global RF bands. Its high reliability, low latency, and voice support of Rel.14 LTE Cat-M1 (eMTC), along with extended coverage and delay tolerance of Rel.14 LTE NB-2 (NB-IoT), make it a robust, cutting-edge modem solution. And 2G/E-GPRS support is designed to allow for connectivity in areas where LTE IoT is not yet deployed.

Ultra-low power for long battery life

Qualcomm 9205 features reduce power consumption by up to 70% in idle mode compared to its predecessor. This power consumption reduction, along with an ultra-low system level cutoff voltage and advanced battery management features, allows Qualcomm 9205 to support wide range of batteries with extended battery life.

High level of integration

Qualcomm 9205 is 50% smaller than its predecessor. With integrated flash, RAM, and RF front-end, it is also more cost effective.

Integrated GNSS receiver

Qualcomm 9205 uses the latest generation (gen9) Qualcomm® GNSS engine, with support for both a dedicated GNSS antenna and a cellular + GNSS shared antenna, for maximum design flexibility on the end-device.

Hardware-based security foundations

Qualcomm 9205 features a comprehensive security framework, including Qualcomm® Trusted Execution Environment. The solution is a FIPS certifiable cryptographic hardware platform and includes features for storage security and key provisioning, debug security, hardware crypto, and secure boot.

Powerful processor and software suite

Robust application and services are enabled by a variety of hardware and software components including: an ARM Cortex A7 processor, ThreadX and AliOS Things RTOS’s, and a comprehensive set of native networking protocols. Additionally, Qualcomm 9205 comes equipped with an LTE IoT SDK with comprehensive set of APIs for additional application and service enablement.
