Test and measurement (T&M) vendor Anritsu has worked with chip provider Qualcomm to showcase peak throughput for a Category 6 LTE device and network simulator using 20+20 MHz Carrier Aggregation (CA).
The two companies have jointly performed tests with a device based on the new Qualcomm Gobi 9×35 modem, an LTE Advanced World Mode Category 6 chipset solution, said Anritsu in a statement.
Both the Gobi 9×35 and Anritsu MD8430A LTE simulator support CA with two LTE FDD or TDD component carriers (CCs), each with a bandwidth of up to 20 MHz, allowing Category 6 peak data rates of 300 Mb/s in the downlink.
To ensure the functionality and performance of a Category 6 CA device, the LTE network simulator should be capable of testing under a range of conditions, including bidirectional downlink/uplink traffic, RF impairments, and a variety of Secondary Component Carrier (SCC) conditions.
In addition, the simulator should be capable of dynamic scripted protocol-level testing and not just replication of static conditions. The MD8430A is a LTE Simulator that offers these CA capabilities, such as implementation of Hybrid Automatic Repeat Request (HARQ), under high throughput conditions.
Gobi 9×35 is Qualcomm’s fourth generation of multimode LTE modems and is leading the mobile industry to the next phase of LTE Advanced with support for up to 40 MHz carrier aggregation on LTE FDD and TDD.
The MD8430A is a scalable LTE network simulator, with five models ranging from Functional Test Model (FTM) to Performance Test Model (PTM), and available software options for both LTE FDD and TDD for any model. The associated Rapid Test Designer (RTD) graphical test software enables quick scripting of tests, with a user interface as well as available layer 3 and lower- layer libraries.
With the addition of the MD8430A-085 Carrier Aggregation option to either of the two top models, two CCs with 2×2 MIMO are available in the downlink (up to 40 MHz total), with support for Category 6 and up to 300 Mb/s downlink throughput.
