Test system enables LTE-Advanced throughput evaluation

July 12, 2017 // By Christoph Hammerschmidt
Anritsu Corp. has expanded the functionality of its MD8475B all-in-one base station simulator family: The Enhanced Multi-Signalling Unit MD8475B-071 and LTE 4x4 MIMO Option MX847550B-041 enable users to configure a simulation environment for IP data communications combining 4×4 MIMO with high-order modulation (256QAM) and carrier aggregation with a total throughput up to 1 Gbps.

Previous 1 Gbps simulators required difficult setup using several pieces of equipment, but the all-in-one MD8475B simplifies measurement to not only increase test efficiency but also to cut capital expenditure, Anritsu claims.

Strengthening the MD8475B functions with the new Enhanced Multi-signalling Unit MD8475B-071 hardware and LTE 4x4 MIMO Option MX847550B-041 software for evaluating broadband communications will play a major role in the development of LTE 4x4 MIMO DL mobile terminals.

Mobile data traffic has exploded in recent years due to the widespread popularity of mobile phones and increasing numbers of rich-content services, and mobile data traffic is expected to continue expanding due to future deployment of the Connected Car, and the Internet of Things (IoT). Mobile operators worldwide want to provide stable high-quality communications services and are not only increasing the capacity and speeds of existing networks, but are also investigating next-generation communication systems. Deploying these 1 Gbps data rates are a key step towards offering 5G enhanced Mobile Broadband (eMBB) services.


The increasing data rates of commercial mobile phones have resulted in problems arising with operating system freezes, heat generation, and battery consumption due to the higher load conditions. Solving these issues requires a high-stability, high-reproducibility evaluation environment at every stage from early R&D to product release evaluation.

The Signalling Tester MD8475B supports evaluation of various communications technologies ranging from LTE-Advanced to 2G. Its wide test coverage and easy operability using up to 8 RF test ports, plus SmartStudio (state-machine GUI) with a wide variety of parameter settings, facilitate the task of configuring an evaluation environment for mobile terminals supporting carrier aggregation.
