Anritsu Announces Advancement in 5G Sub-6GHz Measurement

Anritsu Corporation has announced the expansion of the company’s Universal Wireless Test Set MT8870A software. The new up gradation is sought to support the new 3GPP5G Sub-6GHz New Radio(NR) RF measurement standards.

Using the developed 5G Sub-6GHz NR Up linkTx Measurement and Downlink Waveform File software options will support non-signalling based 5G Sub-6GHzTRx tests.

3GPP Release 15 was announced in December 2017 defining the 5G NR standards. Apparently national telecom operators are targeting early 2019 for rollout of commercial 5G services and have announced an accelerated timetable for practical trials.

With a seamless frequency band up to 6 GHz and a bandwidth of 160 MHz as standard features:

• The advanced MT8870A platform does not require hardware upgrades to support the 3GPP 5G Sub-6GHz defined test conditions, enabling users to expand functions for 5G Sub-6GHz NR while minimizing upgrade cost risks.
• The MT8870A is a popular tester for mobile devices, featuring industry-best measurement speeds and customized turnkey solutions.
• Adding support for 5G Sub-6 GHz NR measurements will help play a key role in smoothing deployment of advanced cellular wireless technologies.

The Universal Wireless Test Set MT8870A is a measurement platform for mass-production of various wireless communications equipment and modules. The main unit accommodates four high-performance test units, each operating completely independently to perform measurements of up to four pieces of wireless equipment or modules in parallel. Adding the released software expands the MT8870A functions to support the 5G Sub-6GHz tests defined by 3GPP Release 15 (Tx power, frequency, modulation accuracy, Rx sensitivity, etc.) with automatic, fast measurements.

In addition, this powerful MT8870Aplatformsupports continuous line testing of next-generation mobile devices incorporating 4G + 5G + 11ax + Bluetooth 5 technologies to help cut production-line testing costs.

Key Markets and Applications

■ Target Markets: 5G Chipset vendors, module vendors, and finished-product vendors

■ Applications: PHY layer (RF) tests of 5G equipment and devices

Although the 3GPP 5G NR standard defines use of frequency bands up to 52.6GHz, early deployments will be focused on the Sub-6GHz spectrum (frequency band below 6 GHz), which has the merit of offering services with frequencies near 4G LTE, such as mobility and wide area coverage, where 5G is expected to play the main role until around 2020. Support for this Sub-6 GHz standard is expected to be the first step for vendors of 5G devices, such as smartphones.
