  • Full flexibility in message parameterization
  • Several character types supported (e.g. Chinese, Korean and Japanese)

Extensive parameterisation of CMAS or ETWS messages incl. language type (e.g. Chinese, Korean, Japanese)

eMBMS (evolved Multimedia Broadcast Multicast Service)

  • CMW500 includes all BM-SC (broadcast multicast service center) service layer features for full eMBMS device verification
  • CMWcards test scripts are suitable for both eMBMS UE C-plane (signaling) and U-plane (user data) middleware testing
  • Independent R&S eMBMS mini service layer inside CMW500 for all required eMBMS features just as:
    >> PDN gateway multicast routing
    >> FLUTE
    >> Service Announcements
    >> DASH video streaming
    >> (dynamic adaptive streaming based on available datarate)
    >> PCAP or IP replay possible
  • Flexible configuration to adapt network operator settings in the lab

LBS (Location Based Services)

  • Simulate AGNSS satellite systems within CMWcards test cases
  • GPS, GLONASS and Beidou
  • Can optionally be combined with system simulator R&S SMBV for dynamic scenarios or hybrid constellation
  • Useful to check e.g. location capabilities of the mobile device
  • e911 emergency call tests for North American operators
