GM551A series is a wireless communication module
supporting LTE category 4. It delivers maximally 50Mbps
uplink and 150Mbps downlink data rates. It can also be fully
backward compatible with existing 3G and 2G networks.
GM551A features diversity reception. So it can effectively
improve the communication quality and reliability of wireless
connection.
The module provides a variety of network protocols
(PAP/CHAP/TCP/UDP) and a variety of functions
(GNSS/Remote wakeup/SMS/WelinkOpen ™) and so on,
these protocols and functions can be used in many IoT
(Internet of Things) applications.
This series module is produced and designed according to the
requirements of IATF 16949:2016, and conforms to the
quality control procedure such as APQP and PPAP. GM551A
works within wide temperature range, has good EMC
characteristics and excellent mechanical and reliability. It is
suitable for vehicle application.
