Here we talk about 2 main 5G T&M Solutions from Anritsu

  • Radio Communication Test Station MT8000A
  • 5G NR Mobile Device Test Platform ME7834NR

Background: 5G mobile communications systems use multiple connections to meet the need for increases in mobile data traffic volumes as well as new functions such as ultra-low latency. 3GPP determining the standards released the 5G NR non-standalone (NSA) specifications for making connections via multiple radio technologies, such as LTE, in Release 15 in June 2018. Release 15 presumes the use of frequency bands up to 52.6 GHz and specifies the band from 450 MHz to 6 GHz as FR1 (Frequency Range 1), and from 24.25 GHz to 52.6 GHz as FR2 (Frequency Range 2). FR1 assumes use of the same wired tests as conventional wireless technologies whereas FR2 assumes OTA (Over the Air) testing.

Radio Communication Test Station MT8000A is a new platform for developing 5G communications terminals, chipsets and devices. With support for both signaling and RF tests, this all-in-one platform can be configured easily for various tests, including RF, protocol, and use-case tests matching the module construction. Anritsu—the leader in 4G testing—is also now taking the lead in 5G.

Solutions Supporting the Automotive Evolution

ELE Times: Please tell us about the solutions for supporting the automotive evolution that enables Mobility as a Service (MaaS) simulation on the desktop. In what ways these solutions are going to be helpful for the automotive industries?

Madhukar Tripathi: Various key technologies are being developed for the advancement of autonomous driving and the realization of a connected society. Cellular V2X (C-V2X), which uses a cellular network capable of high-speed, low latency communication, is one of them. It is critical to confirm that reliable communication can happen under various conditions through wireless verification and use case verification. Anritsu provides a solution that enables Mobility as a Service (MaaS) simulation on the desktop and allows intuitive operation to evaluate the C-V2X communication function of the in-vehicle device.

Anritsu’s solution for evaluating C-V2X PC5 communications functions features an easy-to-understand GUI which eliminates the need to program test scenarios, helping cut equipment configuration costs.

C-V2X PC5 for implementing the connected car is a key element for self-driving vehicles and is defined by 3GPP Release 14. The PC5 interface handles data communications about dangerous road conditions and driving support while the low-latency and high-reliability C-V2X communications technology makes the connected car a reality.

The LTE V2X PC5 Communications Software MX725000A works with the communications reference module, GNSS simulator, and V2X emulator software to evaluate the C-V2X PC5 communications functions, which are expected to become widespread in future vehicle-to-vehicle and vehicle-to-roadside communications. This software supports the typical use cases defined by national ITS standards.

5G NR Field Test Solution

ELE Times: What new testing solutions Anritsu is providing for the 5G NR Field test?

Madhukar Tripathi: The expansion of high-speed, large-capacity communications, such as 5G NR, demand for installation of Core, Metro and Access networks is increasing, as well as simultaneous development of devices for high-speed lines. Installing and maintaining end-to-end lines and increasing workloads will require more efficient measurement solutions.

The handheld Field Master Pro MS2090A IQ capture and streaming option captures IQ data at frequencies up to 54 GHz. Providing real-time signal capture, users can get unrivaled insight into interference by capturing and analyzing interfering signal bursts that cannot be monitored with conventional swept-tuned spectrum analyzers. Additionally, new electromagnetic field (EMF) measurement enables the monitoring of electric field power levels, confirming that the total radiated power does not exceed government (FCC and ICNIRP limit) recommendations and the site is safe for both the public and installers.
