Spirent Vertex offers immediate advantages for users focused on spatial MIMO filtering, carrier aggregation, and MIMO OTA, which are rapidly evolving to deliver improved service coverage and QoE (quality of experience) for mobile users. Vertex simplifies complex test setups by minimizing the amount of hardware required, providing an intuitive and user-friendly graphical user interface, and utilizing field-upgradeable RF modules for diverse test configurations.
“CTIA’s MIMO OTA 1.0 test plan was launched in June 2015 and is on track to become mandatory for all new device designs in the coming months,” says Ron Borsato, co-member of the CTIA OTA working group and principal architect at Spirent Communications. “It starts with 2x2 downlink-only MIMO, but customers need solutions that can scale to handle the sophisticated MIMO modifications that will soon be available. High density is also a challenge for other standards and custom tests being developed to ensure users experience the quality of life promised by 5G’s next-generation services.”.
“MOTA MIMO standards and carrier-specific performance requirements will utilize an increasing number of antennas in the multi-probe anechoic chamber (MPAC) to test more complex applications, such as carrier aggregation. These requirements place a significant burden on the amount of hardware and space needed to perform these tests,” commented Bryan Sayler, Senior Vice President of Test Solutions at ETS-Lindgren. “Spirent Vertex is a small-footprint channel emulator that fits in conventional instrument racks, allowing us to upgrade a basic MIMO OTA test setup to support complex configurations of up to 32 channels. We have successfully partnered with Spirent to remain at the forefront of OTA testing and welcome the industry to the arrival of Spirent Vertex.”
