The Global System for Mobile Communications Service is the most widely adopted, digital cellular technology in use today. CDMA uses code division techniques (CDMA) to optimize the call carrying capacity of a wireless network. CDMA also provides a number of carefully standardized and broadly supported capabilities.

2.5G mobile communication technology (CDMA 1x) 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 CDMA 1x 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.

Internet-enable any RS232 device over CDMA cellular networks reliable solution for IP-based communication and CDMA network services low-cost, non-PC devices running M2M applications mediate the connection between a serial port device and the Internet eliminate the need for Internet programming and minimizes changes to the host application a real plug-and-play device
