Zoned All-Optical WiFi for Guest Rooms: Independent Archiving of Real-Name Authentication Logs

This article analyzes the bottlenecks of centralized archiving in medium and large hotels, including inefficient log retrieval, coarse-grained management, and weak security isolation. It introduces how the all-optical network’s zoned coverage and independent regional archiving solution enable refined log management. Aligning with cybersecurity regulations on data retention, it leverages all-optical WiFi to deploy segmented networks across hotel areas and uses gateways to achieve independent regional log storage and archiving. This delivers high-speed log retrieval, differentiated retention, hierarchical permission control, and precise independent auditing, helping hotels efficiently comply with real-name network log management requirements.

Management Bottlenecks of Centralized Full-Network Archiving

In the network management practices of medium and large hotels, internet access logs are typically centrally archived—logs from all guest rooms, public areas, and administrative spaces are stored on a single server. This model works for small-scale operations but exposes three key limitations as room counts grow and business areas expand.

Inefficient retrieval is the primary pain point. Logs from all regions are mixed in one database, requiring full-table scans to retrieve records for a specific room or period. Response times degrade sharply as data volumes grow. A 200-room hotel reported that after six months of operation, querying one day’s logs by room number took over 30 seconds, severely delaying police compliance checks.

Coarse-grained log management is the second issue—mixed logs from different regions hinder independent regional management and auditing. For example, hotels may need different retention policies for guest rooms (180 days) and public areas (270 days), which requires complex configurations in centralized systems.

Weak log security isolation is the third risk. Centralized storage means all regions share the same storage space and access permissions. When regional managers need to view local logs, they either receive full database access (posing privilege escalation risks) or rely on headquarters transfers (causing inefficiencies).

Policy Compliance Requirements for Log Management

Hotel internet access log management must strictly comply with MPS Decree No. 82 and MPS Decree No. 151. Decree No. 82 mandates public venues to retain internet access logs, while Decree No. 151 specifies retention standards. The revised Cybersecurity Law, effective January 1, 2026, extends the minimum retention period to 180 days, requiring logs to include user identifiers, terminal device information, access times, and IP assignments, with support for conditional retrieval and export.

Additionally, policies require log data to support security isolation—differentiated access permissions must be set for logs from different regions based on management needs to prevent unauthorized viewing. These requirements mean medium and large hotels must move beyond "unified storage" to achieve refined management with regional segmentation, permission-based access, and independent auditing.

Zoned Coverage: Regionalized Deployment of All-Optical WiFi

The core of zoned coverage is dividing the hotel network into independent coverage zones by functional area, each with a dedicated all-optical WiFi system. A typical zoning scheme includes:

Guest room zones: Divided by floor or building, with each group of ONUs connected via splitters to corresponding PON ports on the M1 gateway.

Public zones: Lobbies, restaurants, meeting rooms, and fitness centers as independent segments.

Back-office zones: Isolated from guest networks with physical separation.

The all-optical network architecture inherently supports this deployment. The M1 multi-service security gateway provides multiple PON ports, each linking to an independent fiber serving one zone. Zones are isolated via VLANs without interference. This shared physical fiber, logically isolated network design maximizes fiber capacity while ensuring regional segregation.

Each zone’s ONU/AP delivers independent wireless signals, with adjacent zones minimizing co-channel interference via channel planning and power adjustment. Since ONUs connect directly to the M1 without cascading bottlenecks, every zone enjoys dedicated high bandwidth. Fault isolation is another key benefit—a fiber/ONU failure only impacts the affected zone, enabling rapid troubleshooting.

Independent Regional Archiving: Refined Log Management

Building on zoned coverage, logs are independently archived by region. Each zone maps to a dedicated storage partition on the M1 gateway. Logs generated by guest authentication in a zone are automatically stored in its partition, isolated from other zones.

This design delivers four management advantages:

Dramatically faster retrieval: Logs are stored by zone, so queries for specific rooms only scan the relevant partition. For a 200-room hotel divided into 8 floor zones, each partition holds just 1/8 of the total data, reducing query times to 3–5 seconds.

Differentiated retention policies: Configure 180 days for guest rooms, 270 days for public areas, and 365 days for VIP zones.

Regional access permissions: Floor supervisors only view their floor’s logs; lobby managers access only lobby logs; IT admins have full privileges. Hierarchical access minimizes privilege escalation risks.

Independent auditing: Security incidents in one zone can be analyzed by exporting only its logs, avoiding disruptions to other zones and limiting investigations to specific areas.

Technical Implementation of Independent Archiving

Independent regional archiving relies on three key all-optical network capabilities:

PON port binding: Each M1 PON port maps to a network zone and its storage partition. Logs from ONUs under the port auto-write to the assigned storage without manual intervention.

VLAN tagging: Each zone uses a unique VLAN ID, automatically attached to logs to route them to the correct partition.

Dedicated indexing: Each zone’s storage has independent indexes (time, MAC, room number, authentication method), enabling fast intra-zone searches.

Capacity management: Each zone has storage limits and retention rules. Expired logs are auto-purged when thresholds are reached, with fully automated maintenance.

Application Results and Suitable Scenarios

A 250-room business hotel with restaurants, meeting rooms, and a fitness center previously used centralized log management. After six months, its database accumulated over 2 million records, slowing retrieval significantly. Post-deployment of the all-optical zoning solution, the network was split into 10 zones (6 guest, 3 public, 1 back-office) with independent log storage. Retrieval times dropped to under 3 seconds, and differentiated retention periods were applied. During a recent police inspection, IT staff selected the relevant zone, entered the room number and time frame, and generated a standardized report in 3 seconds.

Zoned coverage and independent regional archiving are ideal for:

Medium/large hotels with 100+ rooms (high log volumes, critical for fast centralized retrieval).

Mixed-use hotels with complex functional zones (diverse log management needs across business lines).

High-end hotels requiring strict data isolation (VIP floors need granular log access controls).

For these hotels, the zoning solution not only improves coverage but elevates compliance from coarse to refined—every log has a clear regional 归属，and every retrieval completes within predictable timeframes.

Conclusion

In today’s hotel industry, real-name log retention is no longer just data storage—it is central to cybersecurity operations, police compliance, and internal governance. Traditional centralized log management can no longer scale with large, diverse hotels. AINOPOL’s all-optical WiFi zoning architecture, paired with independent regional log archiving, balances stable coverage, uniform wireless signals, and compliant log management.

FAQ

Q: Do multiple guests sharing one room need separate real-name authentication?

A: One primary authentication per room allows multiple devices to connect simultaneously without repeated verification—convenient and compliant.

Q: Are log records searchable by time period?

A: The backend supports precise filtering by date, room number, real-name details, and terminal device for fast log retrieval.

Q: Can cross-network interference occur on the hotel’s internal network?

A: Advanced logical isolation ensures guest room networks are fully independent, preventing unauthorized access, network theft, or data interception.
