Overview

GM551A is designed to provide customers with global network coverage on the connectivity of LTE. It delivers 50Mbp-up and 150Mbps-down data rates on LTE FDD networks and can also be fully backward compatible with existing EVDO, UMTS and GSM/GPRS networks.

Rx diversity which allows the end-device to be equipped with two distinct cellular antennas improving the quality and reliability of the wireless connectivity.

A rich set of internet protocols (PAP and CHAP used for PPP connections)and abundant functions (GPS/A-GPS, FOTA, Band Lock, Open RIL code, MMS, SMS) extend the applicability of the module to a wide range of M2M applications.

GM551A also allows the integration of automotive and other applications requiring assured extended operating temperature range and mechanical ruggedness within the ever-shrinking space inside electronic bays in trucks, automobiles, and other mobile platforms.

For the GM551A 4G on-board front-mounted communication module,its research and development has strictly followed the TS16949 quality controlrequirement. It has been applied commercially in a number of front-mountedprojects; GM551A 4G on-board front-mounted communication module supportsdomestic 4G Netcom businesses, with leading performance in the industry, andvery good liability and ease of use. It has been widely used in domesticmainstream OEMs and T-BOX of Tier 1 and iHU all-in-one machine. The massproduction and shipment of the are also available on various front-mountedproducts.
