IWAVE MANET Radios Power Guangdong Provincial-level Emergency Communications

Introduction

In the past three years of severe flooding, Shaoguan, Qingyuan, Meizhou, and other areas in Guangdong Province have repeatedly experienced extreme situations of "triple disruption"—internet, power, and road outages. Once traditional communication facilities fail, disaster areas become "information islands," hindering rescue command and making it difficult to promptly ascertain the safety of the people.

To solve this problem, IWAVE COMMUNICATIONS CO., LTD, in collaboration with relevant departments in Guangdong Province, built the nation's first "triple disruption" emergency communication network, covering 180,000 square kilometers across the province. This network achieves fully wireless connectivity and stable communication around the clock, becoming a benchmark project for provincial emergency communications.

Background The Communication Lifeline During Disasters Since 2020, many parts of Guangdong Province have been hit by severe floods, resulting in destroyed roads, power outages, collapsed base stations, and the complete failure of conventional communication methods. Rescue teams were unable to reach the affected areas, disaster information could not be disseminated, and command centers were rendered inaccessible. The Qingyuan Municipal Emergency Management Bureau, in summarizing its rescue experience, pointed out: "The biggest bottleneck was the lack of communication equipment reaching the villages." When disasters struck, village officials were unable to report the situation, hindering the precise deployment of rescue forces.

Solution Three-Tier Architecture for Comprehensive Coverage The IWAVE team deployed an emergency communication system based on MANET self-organizing network technology, employing a three-tier network architecture: Tier 1: Provincial Command Layer (1 channel) Located in the provincial command center, coordinating emergency resources across the province. Tier 2: Municipal Command Layer (3 channels) Covering all cities and prefectures, supporting regional dispatch. Tier 3: Tactical Communication Network (3-6 channels) Reaching into townships and villages, ensuring communication for frontline rescue teams.

Construction Scale

Total number of base stations in the province: 500 (including nearly 200 emergency trunking base stations)

Coverage area: 180,000 square kilometers (full coverage of the entire province)

Core functions:

• Network-wide radio positioning
• Voice and SMS transmission
• Network-wide monitoring and recording
• Multimedia dispatch "one map"
• Interoperability with industry standard systems

Practical Results: From "Three Disconnections" to "Three Connections"

During numerous major flood relief efforts in Shaoguan, Qingyuan, and Meizhou, this system played a crucial role:

Disaster Information Outreach: Even with a complete public network outage, villages could still report water levels and the number of people trapped via emergency radio.

Rescue Forces Accessibility: Multiple rescue teams achieved horizontal communication and coordinated operations through the tactical communication network.

Command and Orders Effectively Delivered: The provincial command center dispatched orders through a unified map, ensuring direct delivery to the front lines.

In subsequent disasters, the Qingyuan Emergency Management Bureau no longer required on-site technical support from the manufacturer. Because of the implementation of the "peacetime-wartime integration" policy, villages checked online daily through the system, making emergency communication an integral part of daily operations.

Conclusion

Replicable "Guangdong Experience"

Guangdong Province's experience demonstrates that true emergency communications cannot rely on temporary setups, but rather on systems that are "usable in daily life and reliable during disasters."

This model is suitable for:

• Flood- and typhoon-prone areas
• Remote areas such as mountainous regions and islands
• Border areas, forest areas, and mining areas with weak infrastructure
