Signal transmission of monitoring devices, sound collectors, signal jammers and other equipment must feature high bandwidth, low latency and zero packet loss to avoid video stuttering, audio delay and data loss. The network architecture shall support centralized equipment management to enable real-time monitoring of the online status of all terminals.

Anti-Cheating System

Signal shielding devices shall cover the full frequency band from 40MHz to 6000MHz with radiation intensity no more than 10μW/cm² in compliance with GB8702-2014 standards, and support time-period adjustable power output. Identity verification devices shall adopt multi-modal biometric recognition technology with an error recognition rate lower than 0.1% to eliminate exam impersonation.

Examination Management & Emergency System

The broadcasting system shall adopt dual-backup design to ensure uninterrupted listening tests. Access control, electronic class boards, emergency broadcasting and other facilities shall be stably connected to the network for unified scheduling. Data transmission and storage shall comply with information security norms of the education industry to prevent data leakage and tampering.

II. Core Demands and Implementation Approaches

All construction requirements for standardized examination rooms are essentially aimed at safeguarding examination fairness, ensuring data security and fulfilling regulatory compliance.

Video monitoring and audio collection achieve full-process traceable records to curb exam impersonation and cheating behaviors, enabling quick verification via recorded footage in case of disputes.

Stable network transmission guarantees real-time online supervision, allowing command centers to keep track of on-site conditions and respond to emergencies promptly.

Reliable operation of anti-cheating equipment blocks electronic cheating means and maintains impartial examination order.

Standardized data storage and secure transmission prevent exam-related data leakage and alteration, complying with relevant laws and regulations on educational information security.

The biggest challenge in renovating ordinary classrooms into standardized examination rooms lies in satisfying all demands within limited space and budget:

Traditional copper cables are restricted in transmission distance with severe signal attenuation, incapable of supporting stable transmission of high-definition videos and audios;

Devices of various brands with inconsistent interfaces lead to separate wiring for different systems, causing messy circuits and difficult fault troubleshooting;

Insufficient operation and maintenance staff makes centralized management of large-scale equipment impossible, resulting in delayed fault detection;

Long renovation periods disrupt regular teaching activities, and the existing network fails to be compatible with newly added anti-cheating facilities.

To solve these problems fundamentally, it is essential to optimize the underlying network architecture by adopting the Fiber-to-Classroom and multi-service integrated bearing mode. A unified network carries all on-site services to simplify wiring, reduce maintenance workload and upgrade overall network performance.

Construction & Operation Specifications

Renovation construction shall not damage original teaching facilities, and line layout must meet lightning protection and fire safety standards. Centralized operation and maintenance management shall be implemented for all devices to lower the difficulty of large-scale fault inspection.
