> CSM5200™

Qualcomm CDMA tec's CSM5200™ Cell Site Modem (CSM™) is a Wideband Code Division Multiple Access (WCDMA) digital baseband modem for infrastructure and test equipment that supports the UMTS Frequency Division Duplex-Direct Spread (FDD-DSalso referred to as ITU IMT-2000 DS) third-generation (3G) air interface standard for mobile telephony. The CSM5200 device provides significant capacity and performance increases over previous generations of CSMs whilst offering compatibility with existing Global System for Mobile Communications (GSM) networks.

The CSM5200 device provides data throughput of up to 384 kilobits per second (kbps) per user and up to 2 Megabits per second (Mbps) in aggregate. Higher aggregate data rates can be achieved by cascading multiple CSM5200 devices in any given cell. This provides a dramatic improvement over the 9.6 kbps data rate offered by current GSM implementations as well as the data rates achieved through evolutionary standards, such HSCSD, GPRS, and EDGE.

The CSM5200 device will enable a new generation of data-enabled terminals capable of supporting high-speed data applications with rich graphical content, such as wireless streaming video. Network operators will also benefit greatly from cost efficiencies and capacity enhancements, especially in capacity-challenged urban areas that need additional cell sites.
