aiming at the downlink positioning information, connecting a port 2 of the switch SPDT and a port c of the bidirectional coupler; the Bluetooth 1 carries downlink positioning information such as LOCAL NAME in a broadcast signal and sends the downlink positioning information to an antenna for radiation through a passage between a port c and a port d of a bidirectional coupler; indoor equipment such as a mobile phone can receive a broadcast signal of the Bluetooth 1, the signal intensity sent by the Bluetooth 1 is determined by reading LOCAL NAME information, the position of the indoor branch antenna is further determined, and the positioning precision can reach 3 m-5 m.
For the push information, the port 2 of the switch SPDT is connected with the port c of the bidirectional coupler; the Bluetooth 1 carries the push information in a broadcast signal and sends the broadcast signal to an antenna for radiation through a path between a port c and a port d of a bidirectional coupler; an indoor device such as a mobile phone can receive the broadcast signal of the Bluetooth 1 to acquire the push information.

Aiming at the internet of things information, when the internet of things information is determined to be received, the port 2 of the switch SPDT and the port c of the bidirectional coupler are connected, the antenna receives the internet of things information such as temperature and radio frequency information collected by indoor equipment such as an intelligent parking lot and the like, and the internet of things information is sent to the Bluetooth 1 through a passage between the port c and the port d of the bidirectional coupler; when the fact that the internet of things information is sent is determined, the port 1 of the switch SPDT and the port b of the bidirectional coupler are connected, the Bluetooth 1 demodulates the internet of things information, and the demodulated internet of things information is sent to the gateway Bluetooth through a path between the port a and the port b of the bidirectional coupler so that the gateway Bluetooth can monitor the indoor equipment.
