GSM Modem, Industrial Sim Card Modem with High Gain Replacable AntennaPosted by Elinsevan Li on June 5th, 2019 E-Lins GSM modems mainly covers 2G CDMA1x and 3G CDMA2000. For single sim GSM modem, the main model is M300 and M400. Built-in 2G CDMA industrial cellular modules, insert SIM/UIM card to work directly; Built-in UIM card slot, supporting name-flashing (non-uim card); SIM failover/standby APN; CDMA failover for fixed-line broadband connections; Support At command; USB or serial port; CDMA wireless modem has offered much convenience for wireless communication. Like wired internet functions, not subject to WPA restrictions. With the development of wireless communication technology, CDMA products are widely used in data transmission. Especially the emergence of CDMA Modem significantly promote the development of this application and provide simple and practical CDMA communication solutions. E-Lins mobile data products has a long history and are widely used in more than 50 countries and regions, and more than twenty industrial fields, such as power control, water schedule, traffic, oil field, weather forecast, environmental protection, street lamp control, post, bank, CCTV, security surveillance, and many other areas. What is the industrial Sim card Modem?
With the development of wireless communication technology, GPRS products are widely applied in the field of data transmission, especially the appearance of industrial Sim card Modem has promoted the development of this application. Based on providing a simple and practical solution for GPRS communication demand, The E-lins Technology Co., Ltd. in Shenzhen has developed M300 series modem, 4G LTE version, which supports network: 4G LTE (FDD), mobile GSM/GPRS/EDGE or CDMA1x, 3G UMTS HSDPA+ network. The product is specially designed for the complex environment of the industrial site, which further simplifies the interface design. Users can communicate through RS-232 (model DLK-M230), RS-485 (model DLK-M231), TTL (model DLK-M232) level interface, and use simple AT commands to complete the reliable communication of point to point data. What the users face is the AT instruction interface based on serial communication, which saves time and development intensity. At the same time, M300 series modem, 4G LTE version can also be used as a part of the product and combined with products. At the same time, M300 series modem, 4G LTE version can also be used as a part of the product and be combined with products. This industrial GPRS wireless Modem has been tested for many years, so it is a reliable wireless data transmission terminal product. Like it? Share it! More by this author |
