Qualcomm to Support T-Mobile's 600 MHz with New RF Module
Oct 17, 2017, 9:37 AM by Eric M. Zeman
Qualcomm is expanding the number of LTE bands supported by its cellular antennas. Specifically, the company has designed a new RF front-end to support 600 MHz spectrum, or LTE Band 71. T-Mobile will be the primary beneficiary of the suite of RF modules. T-Mobile has a nationwide footprint of this low-band spectrum, which it has already begun to deploy in some rural areas, including Wyoming. Low-band spectrum has greater propagation characteristics when compared to mid-band spectrum, which means it travels further and can penetrate walls more easily. Qualcomm says its new RF module will also benefit IoT devices that use 600 MHz airwaves. Primarily, the QPM2622 and variants are designed for devices based on the Snapdragon 800 Mobile Platform, while the QAT3516 and variants can be used with the Snapdragon 800, 600, 400, and 200 Mobile Platforms. Qualcomm says its new RF front-ends are already sampling with select customers and it expects to see the modules in commercial devices by the end of the year.
