GSM/WCDMA Air Protocol Analyzer
Seamless integration of 3G networks
The PRMT Air Protocol Analyzer (APA) line consists of state of the art interoperability testing tools which analyze the air interface between User Equipment (UE) and Base Transceiver Stations (BTS) in 3GPP networks. The APA allows developers, researchers and inter operability test engineers to perform in-depth analysis of all three layers of the Uu protocol stack with a completely reliable vendor independent tool. Hardware and software development time can be greatly reduced by using the APA. The APA can also assist in reducing the release time to market of new products. In addition, the analysis and location of problems during Inter Operability Testing (IOT) is made easier.
Main Features
• Fully compliant with 3GPP WCDMA/UMTS specification Release ’99 to Release 5
• True air interface analysis: no wired connection required to UE, BTS or Network
• Uplink (UL) and Downlink (DL) analysis
• Layer 1, Layer 2 and Layer 3 complete detailed information
• MAC, RLC and RRC messages
• User and Control Plane analysis
• Real-time message decode and display of Uu interface Layer 1
• Full trace function for target UE during soft HO and Inter-Frequency HO
• InterRAT capability between GSM/WCDMA
• Post-processing and analysis of recorded data (L1, L2 & L3)
• GSM/GPRS/WCDMA
• High Speed Downlink Packet Access (HSDPA)
• High Speed Uplink Packet Access (HSUPA) is currently under development
• Multi Band
• Forward compatibility |
Vendor Independent
A powerful, universal validation tool
The APA monitors and records the Uu air interface with its own internal RF units. This feature has the advantage of not requiring the user to provide a wired connection to the UE, BTS or any element of the WCDMA/UMTS network that is to be tested. As a result, it is a valuable tool to test any piece of equipment that complies with the 3GPP’s Uu specifications.
Evolution with 3GPP
Continuing to evolve
As 3GPP specifications change so does the APA family by incorporating the latest developments. This is possible because of the APA’s modular architecture and its fully programmable FPGA based design. Our group of engineers works closely with developers, vendors and manufacturers to evaluate their needs and anticipate future trends.
InterRAT
Validation of 2G/3G Networks
With the rapid implementation of 3G networks around the world and the necessity of coexistence with previously installed 2G systems, it is critical to have a reliable tool to test the UE’s passage between networks. The APA, with its dual RF internal units and InterRAT option, provides the capability to follow and document the GSM/WCDMA handover.
Inter-Operability Testing
An easy way to troubleshoot
Today different vendors of UE and Node B equipment coexist in most networks around the world. Performing comprehensive IOT is critical for these scenarios especially when combining the various types of equipment. This ensures a smooth operation and system performance. The powerful analysis capabilities of the APA makes it an excellent tool for troubleshooting problems during UE registrations, paging, handovers, etc.
