On March 25, 2022, GosuncnWelink announced the launch of GM520, a new generation of LTE Cat.4 Module, for the global market. The GM520 module is developed based onASR1803 chip platform with leading performance and mature reliable production capacity guarantee. Together with the ME3630 and GM510 module series, GM520 will provide high-quality LTECat. 4 communication services for the global market.

GM520 module is fully compatible with software and hardware design to meet the communication technology needs of many IoT industries in China and overseas markets, which realized fast efficient and flexible integrated application.

● GM520 module adopts the LCC+LGA 29×32mm SMT package, which is compatible with the mainstream packaging design in the industry and is convenient for users to quickly realize the terminal solution. It also supports standard Mini PCIe plug-in packages for flexible installation.

● GM520provides flexible 4G, 3G, and 2G band combinations for carrier networks in different regions ensuring connectivity quality while effectively reducing costs;

● In order to satisfy the user's design requirements of the industry, GM520 supports abundant hardware interfaces including PCM/AUDIO/USB/UART/SDIO/I2C/SPI/USIM/RMII/RGMII/ADC, and provides reference design to facilitate customers to quickly realize the integration of solutions;

● For application protocol, GM520 can support kinds of network protocols including HTTP/TCP/UDP/FTP/MQTT/PAP/CHAP/PPP, as well as standard file system functions at the same time which can enrich customer usage scenarios.

● GM520 supports standard HTTP/FTP remote upgrade function, good maintainability can reduce users' comprehensive operation and maintenance costs.

The GM520 is based on the ASR1803 chip platform, which uses a more advanced 22nm process to improve the performance of the processor, expand the performance in audio processing, communication interface and other aspects, and support PCI-E interface circuits and 100M/1000MEthernet. At the same time, ASR1803 uses the innovative baseband RF integration technology to integrate the independent RF and baseband chips in LTE Cat.4 communication products into a single chip for the first time in the world, resulting in smaller grain area, lower power consumption and more competitive advantages in the market.

It is worth mentioning that ASR1803's more mature, reliable and stable 22nm process ensures a sufficient supply of GM520 modules for customers in a semiconductor industry facing tight supply. At present, the ASR1803 chipset has achieved large-scale application inChina and overseas markets, and "The Chinese chip" has been widely recognized in the high-end market.

Based on the previous generation of products, the GM520 module is specially designed for the business needs of industrial data transmission and the CPE industry. The 4G/3G/2G multi-mode and full band combination guarantee reliable connectivity in the different network environments of Europe, the Middle East, Latin America, Asia Pacific, and other regions. The domestic version of 4G ONLY can provide better cost performance. The peak data transmission rate of 150Mbps downstream/50Mbps upstream provides users with an efficient connection guarantee. The GM520 supports Ethernet, SDIO, PCIe and other hardware interfaces, as well as extended support for analog voice.

Global cellular mobile communication is continuously evolving from 4G to 5G, while LTE Cat.4 still has strong vitality in Europe, Asia, Latin America, and other regions due to its good network coverage, reliable communication connection, and efficiency ratio, and occupies the mainstream position in CPE and industrial gateway industries. According to the TSR report, the LTE Cat.4 CPE market still maintains9.4 a million units of capacity in 2022! The excellent performance of the GM520 module will be the best communication solution for customers in the data transmission routing industry.

GM520 provides quality communication solutions for the data transmission routing industry

As the backbone of high-speed technology in cellular communication, LTE Cat.4module has maintained a continuous growth trend in recent years and has been widely used in many fields such as connected vehicles, security monitoring, industrial IoT, financial payment and so on. According to TSR data, global shipments of LTE Cat.4 modules will reach 88 million units in 2022 and climb to more than 90 million units in the next few years. With the introduction ofGM520 module, GosuncnWelink LTE Cat. 4 module family continues to grow, bringing more and better communication connection choices to industry users!
