Test &
Measurement
Drive-test systems
Hewlett-Packard Company unveiled a family of three portable drive-test systems that provide air-interace measurements for GSM networks. The GSM drive-system capabilities build on HP’s PCS and cellular testers for CDMA. The systems include a receiver-based RF coverage measurement system, a phone-based service-quality-analysis system, and an air-interface measurement system integrates receiver and phone
measurements to provide comprehensive drive-test capability.
The integrated air-interface measurement system, HP E7471A (E-GSM900), controls RF and call-based measurements via PC software. A GSM test mobile phone supplies critical call-based performance indicators, while the digital receiver measures the power of all GSM channels and decodes the base station identity code (BSIC), while providing interference-management tools and complete characterization of RF coverage.
Customers interested only in
receiver-based measurement capability can purchase the RF-coverage measurement system, the HP E7451A (E-GSM900). The digital receiver operates independent of network parameter settings, and can measure the power and quality of all GSM broadcast channels.
The phone-based measurement capability of the integrated system is available as the HP E7461A service quality analysis system that uses a test mobile phone to characterize network performance such as dropped call rate, blocked call rate and hand-over failures. It
can measure signal strength and quality, and decode the protocol messaging between base stations and the mobile phone. Customers have the option of an E-GSM900 test phone, a DCS1800 test phone, or a combination of up to four phones. Contact your local HP sales office for pricing and configuration information.
