Network performance from your customers’ perspective
Starting with a phone-only solution, the foundation for in-depth testing has been laid. A phone-only solution will identify trouble symptoms within your network. This solution is ideally suited for established networks and provides users the ability to proactively identify trouble spots, and assist in performing preventive maintenance. A phone-only solution can be expanded to include multiple phones, indoor measurements, data (IP layer)
measurements or digital receivers as your requirements expand.
Extensive phone support
The Agilent E6474A Network Optimization Platform offers extensive support of phones, including the most popular subscriber phones available today. This provides the ability to most accurately simulate the subscriber experience when optimizing networks. Agilent provides rapid integration of new phones to match the demands of the industry. Specialized measurements from these phones give access to Layer 1, 2 and 3 measurements including RLP, RLC/MAC and LLC parameters (where appropriate), essential in the optimization and troubleshooting of wireless networks.
A phone-only solution can be used to:
• Test network parameters that will allow you to quantify how your network is perceived by subscribers
• Evaluate call-processing operations • Perform selected call processing functions
• Measure and report the amplitude of the received base station signal • Measure and report the signal quality of the received base station signal • Read and report the neighbor cell list from the broadcast messages • Report the amplitude of neighbor list base stations
• View and log protocol messages in decoded form for easy interpretation
Network independent problem solving
A receiver-only solution offers users the ability to make measurements independent of the network. Phones depend on parameters in the network to help maintain the call - such as neighbor lists. A receiver-only solution allows you to identify problems independent of the network. For example, in CDMA networks, pilot pollution and missing neighbors can be identified within your network. In GSM networks co-channel and adjacent channel interference problems can be identified, as can missing neighbors. The E6474A Wireless Network Optimization Platform gives many tools at your disposal to help easily identify the cause of these problems.
A receiver-only solution is ideally suited for network build-out and turn-up, band clearing, RF planning, network expansion, and base station installation and maintenance. This solution can be expanded to include multiple receivers, and can support different technologies or data formats. One or more phones can be added to the same platform for comprehensive network management.

A receiver-only solution can be used to:
• Find network problems faster through network independent measurements • Reduce network downtime by identifying interfering signals while the network is live • Manage interference with co-channel and adjacent channel measurements (e.g., GSM
networks) and detection of other spurious signals
• Carry out BCH Analysis on GSM networks, includes BSIC decode feature.
• Perform Pilot scanning for CDMA pilot pollution including multipath measurements and chip delay.
• Do Code Domain Power measurements on IS-95A and cdma2000 1XRTT networks for over-the-air base station testing.
• Perform spectrum analysis, covering both the downlink and uplink bands • Measure Channel and CW power

Comprehensive network management
To perform comprehensive wireless network testing, a phone/receiver combination solution is required. A phone/receiver combination solution allows you to identify network problems, and quickly determine the cause of the problems, assuring the highest level of network optimization and reducing potential negative impact on your customers’ quality of service. The operation of the receiver and phone can be linked, so that the receiver automatically tracks the phones serving cell as you move through your network. Both the phone-only solution and the receiver-only solution can be upgraded to a phone/receiver combination solution. This solution is beneficial for rapid network installation, expansion, and proactive maintenance. Multiple phones and receivers may be added when needed for evaluation and turn-on of new technologies and data formats, or to simultaneously monitor networks occupying different bands.
