There are two different frequency bands, 2.4 GHz and 5 GHz, for wireless connection such as connecting via wireless router or wireless direct.
5 GHz
5 GHz transmission speed is faster than 2.4 GHz with strong signal strength.
When using wireless connection outdoor, do not use 5 GHz. Depending on your country or region, only indoor use is permitted for some bands.
2.4 GHz
2.4 GHz can reach further than 5 GHz.
We recommend using 2.4 GHz for the following cases.
Ø There are obstacles near the router, computer, smartphone or printer.
Ø The router, computer, smartphone and printer are in different rooms.
Ø Communication is unstable although you are connecting to 5 GHz.
If a microwave is nearby, it may cause the slow communication or interruption.
