A captive portal is a web page accessed with a web browser that is displayed to newly connected users of a Wi-Fi network before they are granted broader access to network resources. Captive portals are commonly used to present a landing or log-in page which may require authentication, payment, acceptance of an end-user license agreement, acceptable use policy, survey completion, or other valid credentials that both the host and user agree to adhere by. Captive portals are used for a broad range of mobile and pedestrian broadband services - including cable and commercially provided Wi-Fi and home hotspots. A captive portal can also be used to provide access to enterprise or residential wired networks, such as apartment houses, hotel rooms, and business centers.
Communication device, data transmission method, and data transmission system
A communication device includes a wireless communication module and a processor. The wireless communication module transmits or receives multiple wireless signals, and provides a hotspot, wherein the wireless communication module receives a connection request indicating to connect to the hotspot from a peer communication device, and establishes a wireless connection with the peer communication device in response to the connection request. The processor is coupled to the wireless communication module, and controls operations of the communication device, wherein after the wireless connection is successfully established, the processor utilizes a captive portal mechanism to transmit information associated with a download link to the peer communication device via the wireless communication module; and in response to a download request being received from the peer communication device, the processor transmits predetermined data to the peer communication device via the wireless communication module.
