Channel emulator assesses performance of LTE small cells

New capabilities have been added to Keysight Technologies’ Propsim F32 channel emulator. These capabilities enable manufacturers and mobile operators to efficiently verify the performance of devices and network equipment with LTE-Hotspots and Indoor (LTE-Hi) small cell and LTE-Licensed Assisted Access (LTE-LAA) dual connectivity technology support.

LTE-LAA was first introduced in 3GPP Release 13 and is part of LTE Advanced Pro. Keysight’s LTE-Hi small cell test scenarios were developed in collaboration with China Academy of Information and Communications Technology.

Keysight has 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 conjunction with Propsim F32 multi-link capability and up to 6GHz band support, the enhanced emulator allows users to assess all existing, as well as planned, LTE-LAA Carrier Aggregation and Wi-Fi-offloading field deployment scenarios.

“Propsim’s new LTE-Hi channel model package, together with Propsim’s integrated interference capability, enables us to verify the performance of devices and network infrastructure equipped with TDD-based LTE-Hi,” said Dr. Zhang, CAICT senior engineer. “This results in an enhanced end-user experience in hotspots and indoor environments.”

“We are excited to enable Propsim F32 users with the ability to quickly develop and deliver LTE-Hi small cell capable device and infrastructure,” said Paul Beaver, products director at Keysight’s Device & Infrastructure Testing operation. This was made possible as a result of the specialized test scenarios developed in collaboration with CAICT.”
