Testing Chinese 3G Networks
Comarco Wireless Test Solutions says that it is extending its Prizm Scanning Receiver System to support the emerging TD-SCDMA standard currently being deployed in China. The Prizm System is a scanning receiver used by cellular carriers to deploy, monitor and troubleshoot cellular networks that conform to the TD-SCDMA 3G standard.
"TD-SCDMA promises a significant advance over similar systems, providing both increased capacity and advanced data features and is being positioned to support the rapid growth expected in the China mobile marketplace," notes Mark Chapman, senior vice president and general manager of Comarco Wireless Test Solutions. "With TD-SCDMA, China has adopted a third generation technology that more easily accommodates asymmetric traffic with different data rate requirements on downlink and uplink. Comarco's extensive experience with other CDMA technologies gives us a unique insight into the requirements needed to support this emergent and exciting standard. Furthermore our proven ability to support multiple technologies and frequency bands has allowed us to rapidly bring a superior product to market in support of this unique and growing market opportunity."
The Comarco Prizm scanner supports many new features specific to TD-SCDMA, including DwPTS detection, which simplifies performance analysis by identifying individual DwPTS in a spectrum and facilitates identification of the strongest DwPTS.
In addition, automatic scrambling code decoding simplifies performance analysis by showing the individual PCCPCH, which in turn permits identification of the strongest PCCPCH and eases base station identification. These features provide a complete and independent assessment of the network separate from that reported by the handset, providing validation and verificati on of important RF network parameters. Additionally, advanced statistical time and delay measurements provide automated and accurate delay spread analysis, thus permitting the detection of any synchronization issues. The Prizm also offers a full complement of programmable multi-band RF spectrum measurements in addition to TD-SCDMA modes of operation."
