PAX Technology Limited Room 2416, 24/F., Sun Hung Kai Centre, 30 Harbour Road, Wanchai, Hong Kong Date: July 26, 2017 Declaration To whom it may concern, This is a WLAN/Bluetooth combination antenna with FCC ID: V5PQ20. This WLAN/Bluetooth co-existence mechanism is to ensure that the WLAN and Bluetooth transmitters would not simultaneously operate. Therefore, WLAN and Bluetooth antenna in FCC ID: V5PQ20 should not be considered to be able to transmit simultaneously. Though the users can use WLAN and Bluetooth simultaneously, but the real situation is that WLAN and Bluetooth are used by time sharing and no overlap transmission. Should you have any question, please have my best attention.
