5G RF Testing

5G RF testing is the process of evaluating and verifying the Radio Frequency (RF) technology used in 5G networks. These tests aim to ensure the RF performance, transmission quality, and signal stability of 5G devices in different environments and usage scenarios.

What are the test standards for 5G product certification in Japan?

At present, 5G communication technology has been vigorously launched in various countries in the world, and certification requirements have also followed. At present, 3GPP defines the 5G frequency range, which is divided into FR1 (450MHz – 6GHz, also known as Sub-6GHz) and FR2 (24.250GHz – 52.6GHz, also known as Above-6GHz or millimeter wave), let’s take a look at some of Japan’s requirements for 5G product certification:


1. 5G NR (New Radio) Japan Radio Law certification standards:


Japan Radio Law test standard: Article 2-1-11-30 (terminal), Article 2-1-11-29 (base station)

● 3.7GHz(n77):3600 MHz -4100MHz

● 4.5GHz(n79):4500 MHz -4900 MHz

● 3.7 GHz band or 4.5 GHz band allocated 100Mhz/1 carrier: There are telecom operators NTT docomo, KDDI including Okinawa cellular Softbank, RAKUTEN Mobile

● The maximum antenna power is limited to 200mW (terminal)

● Japan Telecom Law test standard: Telecom Business Law (terminal)



Japan Radio Law test standard: Article 2-1-11-32 (terminal), Article 2-1-11-31 (base station)

● 28GHz (n257):27GHz-29.5GHz

● 2.8GHz allocated 400Mhz/1 carrier: NTT docomo,KDDI,Softbank,RAKUTEN Mobile

● The maximum antenna power is limited to 200mW (mobile terminal)

● Japan Telecom Law test standard Telecom Business Law (terminal)


2. The content of the telecommunications law certification test in Japan MIC certification 5G NR is basically similar to that of LTE. The main tests are:

1)Basic Functions

2)Transmission Timing 

3)Random Access Control 

4)Time Alignment Control 

5)Location Registration Control 

6)Channel Switching 

7)Receiving Level Reports 

8)Inherent Information 

9)Receiving Level Deterioration 


3. Japan MIC certification 5G NR in the Japan Radio Law test content:

1)Frequency Tolerance 

2)Antenna Power 

3)Antenna Power Tolerance 

4)Antenna Gain 

5)Occupied Bandwidth 

6)Unwanted Emission Strength 

7)Adjacent Channel Leakage Power 

8)Leakage Power at No-carrier Transmission 

9)Intermodulation Characteristics 

10)RX Emission Strength 

4. 5G-NR frequency bands planned by major Japanese operators

● Frequency bands used by NTT docomo: Sub 6GHz has n77, n78, n79; Above-6GHz has n257, n260.

● Frequency bands used by Softbank: Sub 6GHz has n77, n78, n79; Above-6GHz has n257.

● Bands used by KDDI: Sub 6GHz has n77, n78, n79; Above-6GHz has n257.
