The R&S CMW500 multi-standard platform from Rohde & Schwarz now offers options for testing the handover between Long-Term Evolution (LTE) and 1xEV-DO networks. All tests are carried out in line with the 3GPP2 enhanced high-rate packet data (eHRPD) specifications.

Manufacturers that address the American and Asian markets with their user equipment or chipsets must perform these tests. In America and Asia, LTE technology is being integrated into existing cdma2000 environments. The LTE user equipment for these networks must reliably function in cdma2000 cells, too. The transition from one infrastructure to the other must work smoothly.

During handover testing, the R&S CMW500 wideband radio communication tester also can simulate a real Internet protocol (IP) connection. Test engineers, then, can find out whether a device continuously transmits the IP user data on both networks during handover.

The R&S CMW500 includes the server function required for this test. This not only enables the user to carry out handover tests but also to simultaneously measure the RF characteristics of the device under test (DUT) for LTE and cdma2000. In addition, Rohde & Schwarz offers LTE handover options for WCDMA and GSM.
