With the development of mobile communication technology, the security problem in communication is getting more and more attention. It is closely related to the users, manufacturers and operators. People get the vital interests in the use of mobile communication while also put forward higher requirements for information security in communication.

CDMA (Code-Division Multiple Access) is a CDMA technology, is a kind of advanced wireless spread spectrum communication technology in recent years in the digital mobile communication process. It can meet the market requirements of high capacity and quality of mobile communication while has high spectrum efficiency and good speech quality, high security, low drop rate electromagnetic radiation, small, large capacity, wide coverage and other characteristics that can reduce the amount of investment and reduce operating costs.

What is 3G CDMA2000 Modem?

CDMA2000 is CDMA20001×EV, it is a kind of 3G mobile communication standard. It has two phases: CDMA20001×EV-DO  (DataOnly) that transmits data by voice separation channel and CDMA20001×EV-DV(DateandVioce) that is an integrated channel combined with data channel and voice channel. CDMA2000 is also called CDMA Multi-Carrier, this system derives from narrow-band CDMA One digital standard, it can directly be upgraded form its original structure and its construction cost is low.

CDMA2000 is a 3G mobile communication standard. Wireless interfaces that meet the IMT-2000 standard of the International Telecommunication Union (ITU) are also an extension of 2GCDMA standard(IS-95, mark CDMA1X). The fundamental signaling standard is IS-2000. CDMA2000 is not compatible with another major 3G standard, W-CDMA.

The 3G CDMA Modem of Shenzhen E-LINS Technology Co. Ltd. is designed and developed on the basis of wireless network's needs. This product adopts industrial grade design standard and has strong capability of resistance to water, moisture, thunder and electromagnet. It is easy-operating and is simple to be installed, it has high-end configurations and multiple interfaces. It has been widely used in industrial fields as its powerful functions can meet application needs in various scenes.
