Description :

EM7455 is a 4G-LTE cat 6 module (FDD & TDD), with a down link data rate of up to 300 Mbps, primarily for Europe, North and South America. Support for Carrier Aggregation (CA) and MIMO. Fall back to 3G-HSPA+DC with Rx diversity. A GNSS receiver is integrated. Supported frequency bands: 4G B1-B5, B7, B8, B12, B13, B20, B25, B26, B29, B30, B41 ; 3G B1-B5, B8. Form factor is M.2, 42 x 30 mm. Designed for high speed industrial M2M and mobile computing solutions, the AirPrime® EM74 series embedded modules deliver high speed connectivity on LTE and HSPA+ networks. Based on the M.2 standard with a USB host interface, the EM series modules offer an easy upgrade path to new network technologies and global access to high speed networks. The M.2 formfactor is also known as NGFF (New Generation Form Factor).
