5 Antenna Information

5.1 Antenna Type

XR1 has two types of antenna, one uses external antenna, another uses an onboard PCB

antenna(default way). Onboard PCB antenna meandered inverted-F antenna (MIFA)

operating in the 2.4 GHz Wi-Fi frequency band.But it has two types of antenna

(1) Onboard PCB Antenna (2)External Antenna

5.2 Antenna Interference Reduction

To ensure optimal Wi-Fi performance when the Wi-Fi module uses an onboard PCB

antenna, it is recommended that the antenna be at least 15 mm away from other metal
