AU (KDDI Network) Frequency Band

If you are going to be going to Japan whether it is for work or vacation you may be interested in renting or buying a SIM card while you are in Japan. There are a few important things that you need to know when you use a MVNO SIM card with your SIM free phone.

Not all phones will be compatible with the Japanese frequency bands. And depending on which provider you are getting the SIM card from the frequency bands will differ. I previously wrote a blog about the Docomo frequency bands and for this blog I will be talking about the AU frequency bands.

So let me first get into the frequency bands that AU uses.

 

The LTE (FDD-LTE) frequency of AU:

-Band 1 (2 GHz band or 2.1 GHz band) / maximum download speed of 37.5 to 150 Mbps

-Band 11 (1.5 GHz band) / maximum download speed of 75 Mbps

-Band 18 (800 MHz band, platinum band) / download speed of 75 Mbps

-Band 26 (800 MHz band)

-Band 28 (700 MHz band)

 

The LTE (TD-LTE) frequency:

-Band 41 (2.5 GHz band, WiMAX 2 + TD-LTE)

You may be wondering what each of the frequency bands are so I will explain more about it in details below.

 

Band 1 (2GHz band or 2.1 GHz band) / Download speed 37.5 to 150 Mbps

As a countermeasure against traffic with the 800 MHz band, the 2GHz band has considerably expanded and the speed has increased as well. Also, AU MVNO does not support 3G data communication so Band 1 is very important.

 

Band 11 (1.5 GHz band) / maximum download 75 Mbps

Band 11 is also used as a traffic countermeasure in the area where there is a lot of traffic with the 800 MHz band and 2GHz band. It is more of a countermeasure against traffic rather than area. There are also some devices that do not correspond to Band 11 so make sure to look into this. In the case that your device does not correspond to Band 11, as long as it is able to pick up Band 1 or Band 18 there shouldn’t be any problems.

 

Band 18 (800 MHz band, platinum band) / maximum download speed 75 Mbps

This Band 18 is also called the Platinum Band which is the main frequency. AU says that there is a population coverage rate of 99%. If you are going to go with an AU MVNO make sure that the device is compatible with Band 18 or Band 26.

 

Band 26 (800 MHz band)

The upload speed of Band 26 is 814 to 849 MHz and the download speed is 859 to 894 MHz. Some devices are compatible with Band 26 but not compatible with Band 18 (800 MHz band) (LG G3 Beat, etc). 800 MHz can be picked up with Band 26 so even if the device does not correspond to Band 18 there shouldn’t be any problems.

 

Band 41 (2.5 GHz band, WiMax 2+, TD-LTE)

Band 41 is used by WiMAX 2+. It seems that the area in which Band 41 is supported is still limited but is expanding little by little.

 

Summary

To summarize everything above, it is important that your device at least supports both Band 1 and Band 18 for AU MVNO. If possible, it would be best to have a device that supports Band 1, 11, 18 (26), 41.
