ME909s-821 is the first LTE cat4 module based on Hi-Silicon chipset. Which is high-quality designed LTE module in small size and Huawei standard LGA form factor, especially for industrial-grade M2M applications such as vehicle telematics, tracking, mobile payment, industrial router, safety monitor and industrial PDAs.
ME909s-821 supports 150Mbps downlink data rate, including enhanced features like FOTA, USSD and Huawei enhanced AT commands.
ME909s-821 supports China region LTE Bands including both FDD-LTE & TDD-LTE, and has two different form factor: LGA and Mini PCIe form factor.
With Huawei pin-to-pin form factor, it is easy to migrate from MU609, MU709 or ME909u family to ME909s-821.
All Huawei modules comply with the RoHS directive and Regional certification.
