Caltta Successfully Escorts Gaokao and Zhongkao Exams in Yucheng, Shandong

The annual high school and college entrance exams concern thousands of families. To ensure fairness and quiet in the exam rooms, education departments across various regions have deployed numerous support measures. During the 2025 entrance exams, Caltta provided professional wireless communication support to the Yucheng Municipal Education and Sports Bureau in Shandong Province. This effort successfully accomplished the communication coverage and dispatch tasks for three key exam school sites, fully supporting students in their journey towards their dreams.

Quiet Exam Protection Starts with Reliable Communication

During the entrance exams, Yucheng City implemented comprehensive "silent" management in exam rooms, strictly prohibiting the carrying of mobile phones and other communication devices into the exam sites. Against this backdrop, to ensure efficient communication and emergency responses among proctors and exam personnel, the Yucheng Municipal Education and Sports Bureau chose the Caltta wireless communication system to build a seamless, smoothly dispatchable, and highly reliable wireless communication support network.

This support project covered the three main exam sites at Yucheng No.1 High School, Yucheng Comprehensive High School, and Yucheng No.2 High School, which form a triangular layout with the furthest direct distance reaching 4 kilometers. The Caltta team conducted multiple onsite surveys and tests based on the actual venue and communication needs, ultimately deploying the Caltta PR900 narrowband digital repeater and installing antennas at strategic high points to ensure no blind spots in coverage, no delays in command, and unobstructed dispatching.

Professional Safeguarding for a Secure and Peaceful Exam

To further enhance the management norms and emergency traceability during the exam period, Caltta equipped each support team with RH596 recording digital walkie-talkies, supporting real-time recording and local storage of onsite communications. In necessary situations, these call records can be traced and analyzed, providing reliable data support for exam security.

At the same time, the Education and Sports Bureau Command Center deployed the Caltta PM790 professional digital vehicle-mounted radio, realizing centralized dispatch and multi-point coordination. This formed a linkage mechanism between the "command center—school exam points—support team personnel", thoroughly improving organizational efficiency and emergency response capabilities during the exam period.

Caltta's communication support system features significant advantages such as stability, reliability, independence from public networks, instant communication, and efficient dispatching. Even in situations of network congestion or complex environments, it can still maintain smooth and unobstructed voice communication, providing solid support for the smooth conduct of the exams.

The service provided to Yucheng City's entrance exams this time was not just a test of technology but also a fulfillment of responsibility. In the future, Caltta will continue to participate in more public service scenarios with professional products, mature solutions, and efficient services, safeguarding every important moment in societal operations.
