A device for implementing an antenna Ping function includes a primary module and a secondary module. The secondary module includes a secondary controller, a multiplexer, a first On-Off Keying (OOK) modem, a second OOK modem connected to the secondary controller and a corresponding multiplexer, and a plurality of antenna radio frequency (RF) ports. The multiplexer is connected to the plurality of antenna RF ports. The primary module is connected to the secondary controller through the first OOK modem. The primary module receives a Ping command transmitted by a base station, generates a Ping message, and transmits the Ping message to the secondary controller through the first OOK modem. The secondary controller transmits the received Ping message to the second OOK modem. The second OOK modem transmits the Ping message to a corresponding antenna RF port through the multiplexer. The antenna RF port feeds back a signal to the base station.
