Keysight Technologies has added new capabilities to its Propsim F32 channel emulator. These capabilities will enable manufacturers and mobile ope­rators to verify the performance of devices and network equipment with lo­ng term evolution (LTE) hotspots and indoor (LTE-Hi) small cell and LTE-licensed assisted access (LTE-LAA) dual-connectivity technology support. The company has also equipped the Pr­o­­psim F32 channel emulator with a flexible integrated LTE interference source, which facilitates straightforward and efficient LTE-LAA and HetNet small cell technology performance testing. In tandem with the existing multi-link capability and up to 6 GHz band support of Propsim F32, the enhanced channel emulator will allow users to assess all existing as well as planned LTE-LAA carrier aggregation and Wi-Fi-offloading field deployment scenarios. Keysight has developed the new LTE-Hi test scenarios in close collaboration with the China Academy of Information and Communication Technology, to further improve LTE-Hi small cell infrastructure deployments.

According to the company, Propsim’s new LTE-Hi channel model package, together with Propsim’s integrated interference capability, will enable users to verify the performance of devices and network infrastructure equipped with time division duplexing-based LTE-Hi small cell. This would provide an enhanced end-user experience in hotspots and indoor environments. In addition, the solution will help Propsim F32 users to promptly develop and deliver the LTE-Hi small cell capable device and infrastructure.
