The MD8480C W-CDMA Signaling Tester has been specifically designed for developing and testing 3GPP wireless devices including protocol stacks, chipsets, and application software. Supporting W-CDMA, HSPA, HSPA Evolution, GSM, GPRS and EGPRS services in a single unit, it is the first HSPA signaling tester in the industry, and the only one with full HSPA capability including 42 Mbps DL/11 Mbps UL maximum data throughput. The MD8480C air interface fully complies with the 3GPP recommendations.

The MD8480C provides chipset and wireless device encoding/decoding tests and regression testing as well as protocol sequence tests such as registration, origination, termination, handover (option), and UE/NW release. It also supports application tests for voice communication, packet communication, and end-to-end communication (using two MD8480C units).

Optional GSM/GPRS/EGPRS features allow testing handover between W-CDMA/HSPA and GSM/GPRS/EGPRS. In addition, the MD8480C is well suited for the development of UMTS wireless devices supporting global bands and sophisticated application software.

  • UE testing for W-CDMA/HSPA, GSM/GPRS/EGPRS support
  • Application testing including HSPA protocol compliance
  • Interoperability testing for wireless devices and networks
  • Research and development of W-CDMA/HSPA (UMTS) chipsets
  • Modulation/demodulation tests for W-CDMA/HSPA mobile devices
  • Achieves 42 Mbps maximum data downlink throughput
  • Configurable for up to 4 base stations for handover testing and other multi-system tests
  • Simulates BTS of W-CDMA/HSPA and GSM/GRPS/EGPRS systems
  • Protocol sequence tests for mobile devices such as call set-up and registration
  • Flexible settings for test parameters and sequences for protocol sequences
  • Protocol Trace function
  • Voice, circuit and packet switched application testing such as AMR voice, IP, PPP and ISDN BER and BLER W-CDMA receiver measurements
