Question

We are planning to commercialize IoT devices with more kinds of wireless telecommunication functions to expand our product portfolio. What do our QA engineers have to do to assure wireless communications quality?

Answer

Evaluating the wireless quality of IoT devices requires testing finished products by simulating an actual usage environment. The actual tests differ per the communication standards, such as Wi-Fi, Bluetooth®, 4G (LTE), 5G, and others, but there are mainly RF parametric and legal compliance tests.

Question

What are the special requirements for RF parametric tests of 4G and 5G NR (New Radio) IoT devices? Additionally, what should we consider when testing 5G NR mmWave band (FR2) which we are considering for future development?

Answer

Let’s use 5G NR IoT devices as an example. On RF parametric tests, you need to evaluate the 5G NR device performance, such as the TRx characteristics and power, by confirming the status of the connection condition between the antenna on 5G NR devices and base station. For LTE, the test items are basically the same as 5G NR, but there are some key differences with the mmWave (FR2) frequency band, requiring an OTA test environment.

Question

How should we confirm compliance with specifications?

Answer

The Radio communications standards for each cellular technology are designed by 3GPP. You can confirm whether the 5G NR device performance meets the 3GPP standards by using Anritsu’s Radio Communication Test Station MT8000A.

Please remember that it is also necessary to conform to the legal regulation in each country. Learn more: What legislation and specifications regulate IoT device and products?

Question

It would be easier for us to automate our testing because we do not have the 3GPP standards details/information. What do you recommend?

Answer

Anritsu’s Radio Communication Test Station MT8000A offers you an easy-to-use automated test tool for RF testing to confirm 3GPP compliance when testing 5G NR devices. This enables you to configure an effective test environment easily and quickly, saving you valuable test time. In addition, the MT8000A supports mmWave (FR2), so you can continue using the same system.

Also, the Radio Communication Analyzer MT8821C offers a similar automated test tool for RF testing of the 2G/3G/4G.

Question

What does the Radio Communication Analyzer MT8821C feature for 2G/3G/4G? Could you also tell us about Wi-Fi solutions?

Answer

With a wider dynamic range and twice the number of RF ports compared to other testers in the market, Anritsu’s all-in-one Radio Communication Analyzer MT8821C is the ideal tester for carrier aggregation and high-order MIMO measurements. Moreover, it also supports legacy cellular communications standards such as 2G/3G, and offers automated RF test tools for efficient test environment configuration.
