Detailed Description

M400g wireless GPRS modem is a kind of gsm cellular modem. Iit's a industrial gprs modem works under GPRS networks. We call it also a RS232 modem or SMS modem because it's with RS232 communication port, and for SMS applications via the software and at command. Providing GPRS connection, the M400g wireless GPRS modem support SMS feature also, which is popular used in wireless M2M solutions. The Global System for Mobile Communications Service is the most widely adopted, digital cellular technology in use today. GSM uses time and frequency division techniques (TDMA and FDMA) to optimize the call carrying capacity of a wireless network. GSM also provides a number of carefully standardized and broadly supported capabilities such as Short Message Service (SMS), circuit switched data (CSD) and General Packet Radio Services (GPRS). Used on the quad band GSM850/900/1800/1900Mhz 2.5G modem is from mobile communication technology (GPRS), which has become widely used of industrials and utilities in recent years and many customers are seeking reliable, flexible and cost-effective data channel to build their information system. Many applications such as ATM, POS, SCADA and surveillance system will require data channels covered all country; this brings a bright future for GPRS data networks applications.Requirements towards information system are varied because of different features of numerous industrial applications. Mobile telecom service providers are required to provide industrial application solutions not only meeting common specifications and also individual special ones. The M400g GPRS Modem allows products to immediately offer the full benefits of GPRS technology, such as permanent online connections plus cost-efficient, high-speed data transmission.
