Rohde & Schwarz offers the only validated protocol test cases for dual carrier HSDPA and LTE-CDMA2000® handover

Munich, Nov 23, 2011 -

Chipset and mobile radio manufacturers are launching more and more products for LTE. Since LTE is still in its initial phase, these products must also support existing mobile radio standards such as GSM and CDMA2000®. This is the only way they can function in areas where LTE is not yet available. Manufacturers use handover tests to evaluate device performance when switching between LTE and other network infrastructures. The Global Certification Forum specifies defined test cases for this scenario. Up to now, there were no validated test cases for verifying smooth transition from an LTE network (release 8) to an existing CDMA2000® 1xRTT network. Rohde & Schwarz has now implemented a TTCN-3 test case that to date is the only one in the world to be validated by the Global Certification Forum. This test case is now available for the R&S CMW500 wideband radio communication tester.

In addition, Rohde & Schwarz is the only T&M equipment manufacturer to offer validated test cases for Dual Carrier HSDPA on adjacent carriers FDD Rel. 8 (GCF WI-129). This technology combines two UMTS channels to achieve a transmission rate of 42 Mbit per second. The test cases are also now available for the R&S CMW500.
