What steps have the hotel WiFi certification system been through? Understanding the process of the system helps hotel network administrators and operators to better understand how the system works, and can quickly locate and check problems when they arise.
Step 1: Terminal connection to WiFi signal
The entire process starts with the WiFi signal, which connects the terminal (cell phone, notebook, tablet, etc.) to the hotel."HOTEL_WiFi"or"Hotel Name - FreeWiFi"), click connection. If WiFi does not have an encrypted password (most hotels are public WiFi unencrypted because encryption codes add to the user ' s operating burden), the terminal will be directly linked to AP and get an IP address (through DHCP). The terminal is now connected to WiFi network but has not been certified, in place"Not certified". The system limits the network access to terminals in this state: an IP address can be accessed by the terminal and DNS can be parsed, but all HTP/HTTPS access is redirected to Portal authentication pages, where no access to the Internet is possible. This restriction is achieved through accessing a switch or ACL (access control list) on aAC (wireless controller) or Portal gateway: traffic from uncertified terminals only allows access to DNS servers and Portal authentication servers, and all other traffic is blocked."Internet access but not Internet access", the terminal can access IP and parsing domain names properly but cannot actually access the Internet, thereby guiding the occupants into the authentication process. It should be noted that WiFi in some hotels has multiple SSIDs for different areas or groups of customers, for example"HOTEL_Guest"(residents only),"HOTEL_Staff"(for staff only),"HOTEL_Meeting"(the conference room is dedicated) The different SSIDs correspond to different VLAN and authentication strategies, with the terminal connected to which SSID enters the corresponding certification process.
Step 2: Portal page self-ejects
The terminal connects WiFi and accesss IP, the occupants open browser to any HTTP website (e.g. 100 degrees, new waves) and request will be intercepted by Portal gateways and redirected to the hotel's Portal authentication page. This redirection process is automatic, and residents do not need to manually enter the address of Portal pages. Modern smartphones (iOS and Android) are built into." Captive port test"Mechanisms: When the terminal is connected to WiFi, it automatically sends a HTTP request to a specific detection server (e.g. apples ' captive.apple.com or Andre ' s connectivitycheck.gstatic.com). If the request is reoriented to Portal pages, the system automatically ejects a login window showing Portal certification pages, and the occupants do not even need to manually open the browser. This auto-ejecting mechanism greatly enhances the resident ' s experience, and the guest can almost immediately see the authentication page when they connect to WiFi. Portal is the first touch of a hotel that displays brand images and pushes information to its guests. It usually contains the hotel ' s Logo, brand pictures, welcome words, authentication options (cell numbers, micromails, room numbers, etc.), input boxes and buttons, terms and privacy policy links. A well-designed Portal page should be clear, fast-loaded, and clear guidelines on how to operate, so that residents understand what to do within seconds. Portal pages can be custom-made by hotels, with different areas, time periods, and groups of people displaying different Portal pages, such as New Year’s page during the Spring Festival, and VIP members display exclusive welcome pages. It is important to note that Portal pages must fit various terminals and browsers, including versions of iOS and Android, different size screens, different browsers (Safari, Chhome, micro-intra-trust browsers, etc.), ensuring that they are properly displayed and operated on all devices.
Step 3: Residents submitting authentication information
The guest selects the authentication method on the Portal page and submits authentication information."Get the authentication code", the system sends a authentication code through SMS gateway and the guest enters the authentication code and clicks"Login"; if micro-mail company WiFi is selected, the tenant scans the two-dimensional code with a micro-mail or clicks on the micro-link button to confirm the connection in the micromail; if room number plus surname is selected, the guest enters the room number and surname, click"Login"Either way, the authentication information submitted by the occupants is sent to the hotel WiFi certification system ' s authentication server for validation. After receiving a certification request, the authentication server performs different verification logics depending on the method of authentication: the mobile phone number authentication requires confirmation that the cell phone code is correct in format, whether the code is valid during its life cycle and whether the authentication code is consistent with the delivery; the micro-credit company WiFi certification requires verification of the validity of the micro-mail OpenID and whether the OpenID has been concerned with the hotel public (if any concern is set); The certificate number + surname requires an interface to the PMS system to check whether the room is validly occupied and the residence name matches. The validation process usually takes one to three seconds. In the verification process, the system records details of authentication requests, including terminal MAC addresses, IP addresses, access to AP locations, authentication times, authentication methods, submitted authentication information, etc., which are entered into the certification log for subsequent audits and retrospectives. If authentication information is failed (e.g., error of identification code, non-existence of home number, mismatch of family name), the system will display bug tips on Portal pages, and the guest can re-input them. Systems typically set failure limits (e.g. locking the terminal or cell phone for a period of time after five consecutive failures) to prevent violent break-ups.
Step 4: System-based delegation of authority strategy
After authentication of the information, the authentication server generates an authorization strategy for the terminal based on a predefined policy and sends it to the access device (exchange or AC) through either RADIUS or Portal agreements. The authorization strategy consists of the following: firstly, access rights, allowing the terminal to access the Internet (relieving previous ACL restrictions), or limiting access to specific network resources only (e.g., quarantine VLAN, only hotel internal servers); Second, bandwidth limits, with upper and lower bandwidth ceilings allocated to the terminal (line 20 Mbps, row 5 Mbps), and different identities of tenants may be given different bandwidths (e.g. VIP member 100 Mbps, regular resident 20 Mbps, employee 50 Mbps); third, length of session, duration of valid authentication sessions at the end (e.g. 24 hours or during a stay in a shop) requiring recertification after long periods; fourth, traffic quotas, which are total flow caps available for this session (e.g. 5GB), exceeding quota speeds or disconnects; VLAN distribution, which divides the terminal to a designated VLAN (e.g. resident VLAN, employee VLAN, isolated VLAN), and separates the user groups from each other. When authorized strategy is sent to access devices, access devices update the ACL and Qos rules of the terminal and the endpoint immediately gets the corresponding network access rights. Residents can then use new browsers or open new web pages to access the Internet properly. The process is transparent to occupants, and residents only see them."Authentication successful, jumping...", and then you can access the Internet. Note that the authorization strategy is based on a terminal ' s MAC address and an IP address, which when the terminal is disconnected from WiFi reconnection, if the MAC address remains unchanged and during the session validity period, the system can automatically release (exempt of recertification) to enhance the resident ' s experience. If the end address changes (e.g. DHCP reallocation), the system needs to re-link the IP and MAC to ensure that the enabling policy is valid.
Step 5: Internet Behavior Monitoring and Log Record
Not when the terminal gets access."Let it go."The system continuously monitors the terminal’s Internet activity and records detailed web logs. The logs include: MAC addresses and IP addresses of the terminals, identity information for residents (cell number, micro-mail OpenID, room number, etc.), access to AP locations and VLAN, authentication time and certification methods, time of entry and end of access, visit site domain or IP address, type of application used (e.g. page views, video, download, social networking, games, etc.), up and down traffic, online duration, etc.. These logs are encrypted according to compliance requirements and have a minimum duration of six months (specific lengths are determined in accordance with local regulations). The system also provides real-time monitoring and unusual detection of end access: if the traffic of a terminal is suddenly abnormally increased (e.g., downloading dozens of GBs in short time), the system may trigger alarms, and managers can check for malicious software or illegal downloads; if an terminal attempts to access prohibited sites or applications (e.g. gambling, pornography, hacking tools, etc.), it can block them under the URL filter strategy and record logs of violations; if an terminal behaviour pattern matches known attack features (e.g. port scanning, violent cracking, DDoS attacks), the system can automatically isolate or disconnect the terminal and notify the administrator. By analysing the Internet logbook, hotels can understand their occupants’ usage of the network and optimize bandwidth distribution strategies; they can detect unusual behaviour and security threats on the web and take timely measures; and they can provide complete retrospective evidence in case of a security incident to help them avoid legal risks.
Step 6: Session termination and resource release
When the occupants leave the hotel, break WiFi or when the authentication session expires, the system terminates the authenticated session of the terminal and releases the corresponding network resources. There are several triggers for termination: one is a voluntary break-up of the terminal, the occupants close WiFi or leave the hotel area, the end is disconnected from AP, AC detects the closure of the certified session by notifying the server that the session will be terminated after the terminal has been delineated; two are an overtime when the valid session exceeds the predefined 24 hours, the system automatically terminates the session and the terminal requires recertification to continue the Internet; Three are manual terminations for managers who can manually force a terminal downline on the management interface, which applies to violations or security threats when detected; and four are check-out connections for PMS, where the room is in PMS status when it is certified."Checked out."When the session is terminated, the system automatically terminates all ACL rules on access devices and prevents the return of WiFi."Not certified"At the same time, the system produces a complete session record containing all information about the terminal from authentication to downline (certification time, downtime, total traffic, online duration, access log summaries, etc.) and writes it into history logs for follow-up queries and audits. The end of the session and resource release are the last steps in the entire certification process, ensuring that network resources are allocated and recovered, preventing departing occupants from continuing to occupy bandwidth, and preventing unauthorized terminals from using expired sessions on the Internet. For hotels, an efficient session management mechanism can increase the use of network resources and reduce operating costs.
The WiFi certification system is a complete closed loop: from terminal connection to WiFi signals, to automatic pop-up on Portal pages, to the submission of authentication information by occupants, to the distribution of authorization strategies under the system, to online behavior monitoring and log records, and finally to session termination and resource release. Each link has clear technical achievement and management objectives that together constitute a secure, controlled, retroactive operating system for the network. Understanding this process helps hotel managers and technicians better plan, deploy and transport the WiFi certification system in order to improve their operational efficiency while safeguarding the resident experience.
