Caltta Strengthens Forest Fire Prevention in Hainan

Shenzhen, China – July 7, 2025 — Caltta Technologies, a leading provider of professional communication solutions, has successfully completed the construction of a dedicated forest fire prevention communication system in Hainan Province of China, marking a significant step toward enhancing ecological protection through digital innovation.

Renowned for its pristine tropical rainforests and rich biodiversity, Hainan island holds a forest coverage rate of 62.1%, making it one of China’s most ecologically important regions. However, the province faces heightened fire risks each year from March to June due to soaring temperatures, low rainfall, and increased human activities. These seasonal conditions have made forest fire prevention and rapid emergency response a pressing challenge.

To tackle these issues, Caltta was appointed by the Hainan Forestry Bureau to launch the "Hainan Forest Fire Prevention Communication System Construction Project". The initiative focused on overcoming key communication barriers—such as signal blind spots, unstable connections, and delayed dispatch—that have historically hindered fire prevention and rescue efforts in remote, mountainous areas.

Caltta deployed a robust, province-wide ultra-shortwave digital communication network using a full suite of wireless products, including the PR900 fixed repeater, PR680 mobile radio, and PH690 digital radio. This dual-tier network, spanning provincial and municipal (county) levels, now ensures seamless daily patrol communications and establishes a rapid-response channel for emergency command during fire outbreaks.

To meet the complex demands of forest fire response, Caltta built an advanced communication command system with four major capabilities:

• Decentralized Authority with Multi-level Dispatch – Enables centralized voice, location, and data management across the province while supporting regional independence and scalability.

• IP Interconnection for Wide-Area Coverage – Connects regional sites through IP networks, eliminating geographical limitations.

• Fixed-Mobile Integration for Agile Deployment – Combines stable fixed coverage with mobile stations to quickly respond to emergencies and fill signal gaps.

“With this intelligent and resilient communication network in place, forest rangers and emergency personnel across Hainan are better equipped than ever to prevent and respond to fires swiftly and effectively,” said Leo Li, Sales Director at Caltta Overseas.

Looking ahead, Caltta remains committed to advancing its emergency communication capabilities, further evolving its solutions to help preserve the island’s invaluable natural environment. Through technological innovation, Caltta continues to empower ecological protection and sustainable development across China.
