About 5G
5th generation mobile communication system “5G”
Features of 5G
5G (5th generation mobile communication system) is the next-generation communication system of 4G LTE, which greatly improves communication speed, time lag (delay), and the number of simultaneous connections, enabling faster and more reliable communication. .
Point 1
High-speed, large-capacity communication
With 5G, new frequency bands will become available for mobile communications, and it is said that in the future, communication speeds will be about 20 times faster than 4G LTE. Download latency is also greatly reduced.
- "Approximately 20 times" is the maximum value according to technical standards, and does not indicate the actual speed of use.
Point 2
low latency
The time lag (delay) between data transmission and reception is about 1/10 that of 4G LTE, greatly improving communication reliability! It is expected to play an active role in remote control of equipment.
Point.3
Simultaneous multiple connections
Simultaneous multiple connections, about 10 times more than 4G LTE, will be possible, and all kinds of terminals, devices and sensors around us will be able to connect to the Internet.
5G frequency band available for J:COM MOBILE (au line)
With J:COM MOBILE, you can use three new frequency bands: ``sub6'', ``millimeter wave'', and ``NR conversion'' (converting existing 4G LTE to 5G).
| band | millimeter wave | sub6 | NR conversion | |
|---|---|---|---|---|
| frequency band | 28 GHz band | 3.7/4.0 GHz band | 3.5 GHz band | 700MHz band |
| band | n257 | n77/n78 | n78 | n28 |
5G area map (au site)
Please see au's 5G area map for the 5G compatibility status of your area.
5G area map (to au site)
- Available frequency bands may differ depending on the terminal's compatibility.
Millimeter wave 28GHz band frequency. High-speed, large-capacity communication is possible with a bandwidth of 400MHz.
sub6 3.7/4GHz band frequency. High-speed and large-capacity communication is possible with a bandwidth of 100MHz each.
NR Conversion Existing 4G LTE band is converted to 5G by applying NR standard. 5G area can be made faster.
