No. Yardian comes with a 2.4GHz 802.11 b/g/n 2T2R Wi-Fi dongle by default.
Data transmission operating on the 2.4GHz frequency can reach around 3 times farther than on 5GHz. Therefore the 2.4 GHz band provides coverage at a longer range.
If you have a dual band router, please turn on the 2.4GHz band.
