On June 2, 2022, GosuncnWelink released a new generation of ultra-small LTE Cat. 1 module GM331H. GM331H is developedbased on the new generation ASR1606 chip platform and in the ultra-small package of LCC 17.7mm×15.8mm, which is the mainstream in the industry, providing customers with convenient and efficient communication solution integration options. With many advantages such as small size, high performance,high security and low power consumption, GM331H is especially suitable forindustry application like IP Camera, asset tracking, financial payment and etc.
The GM331H module adopts LCC 17.7mm×15.8mm ultra-small package scheme, which is the mainstream of the industry. It is fully compatible with LTE Cat.1 module GM331 and NB-IoT module GM122, forming Welink small size modules family. GM331H is compatible with mainstream 2G module package, realizing rapid replacement of communication upgrade from 2G to LTE Cat. 1.
Ultra-small size packages provide industry customers with flexibility in the communication solution integration phase, bringing convenience to all types of IoT applications. GM331H is especially suitable for IP Camera and asset tracking industries which structural dimensions are strictly required.
ASR1606 LTE Cat.1 chip
Same with the module GM196H, the module GM331H is based on ASR1606, ASR’s new generation LTE Cat. 1 chip platform.
Based on the powerful capabilities of ASR1606 chip platform, GM331H can support rich hardware interfaces, analog voice, VoLTE voice and TTS/ recording functions, as well as TCP/UDP/FTP/HTTP/MQTT and FILE operation and other rich software functions and protocols. GM331H supports industrial high reliable communication and mainstream cloud platform protocols in the industry which bring users high-quality LTE Cat.1 communication solutions.
GM331H hascomplete function and reliable performance
To meet the increasing security requirements, GM331H has a built-in Security System that supports 512bit OTP keys and Security BOOT/Strap/Bonding, meeting the industry requirements such as digital financial payment and providing secure and reliable communication capabilities.
The power consumption performance of the new generation GM331H module has been further optimized. In VoLTE voice mode, the power consumption of the call is around 70mA, which is close to the level of 2G call.
