R&S®CMWcards - Features at a glance

Save time during testcase creation using more than 200 cards that can be flexibly combined to create any possible combination of signaling and application test scenarios.

CMWcards offers more than 300 free of charge example tests to speed up creation of regression and stress test campaigns which helps to accelerate the integration test and launch of your mobile device.

Flexible Network Configuration

  • Easy Network and Neighbour cell setup for LTE, WCDMA, GSM and WLAN
  • Roaming configurations to simulate real life roaming scenarios in the lab
  • Multiple cell deployments using CMW500 single instrument or by combining multiple CMW500s
  • Stepwise cell power changes

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
