Border and coastal defense monitoring solutions

1. Overview

China is a large border and coastal defense country, the mainland coastline is more than 18,000 kilometers long, there are many points, long lines, and wide areas, except for key areas, it is difficult to comprehensively carry out real-time network monitoring and coverage. In areas covered by unmonitored networks, border and coastal defense units need to rapidly deploy communication systems to enable seamless connection between various combat units, and to carry out efficient, rapid, and safe execution of border and coastal defense tasks by carrying out battlefield information transmission of various services such as video, command, voice intercom, and telecommunications transmission.

Second, the scheme design

For the maritime wireless communication environment, MESH nodes are deployed on shore-based, ship-based and ship-based to quickly build a multi-hop broadband wireless network with high mobility, anti-interference, strong anti-indestructibility and over-the-horizon transmission, providing comprehensive multimedia transmission services such as voice, data and video between shore-based and ship, and between aircraft and ships.

As shown in the figure above, the wireless private network is connected to the customs command center, the supervision boat is wirelessly connected to the shore-based base station, the base station and the command center network are interconnected, and the single base station covers 30~100km sea area, supporting roaming between base stations; an unbreakable maritime mobile network".

3. System features

• High bandwidth: Adopt software radio architecture, support COFDM waveform, high throughput, up to 70Mbps, ensure large bandwidth transmission, multi-channel video bidirectional transmission at the same time.

• Ad hoc network: The MESH wireless network does not rely on the base station, and has the excellent characteristics of self-organization, self-management, self-healing and self-balancing, supports multi-point jumping, and meets the networking transmission under non-line-of-sight conditions.

• Multi-service: support real-time voice intercom, support high-definition video real-time transmission, support WIFI and access to a variety of application terminals.

• All-IP: It adopts all-IP transparent data transmission and supports end-to-end TCP/IP protocol, which can be easily connected to the higher-level network system.

• Independent research and development: It has complete core technology and intellectual property rights, which can be quickly customized according to user needs, small size, flexible and mobile, and simple deployment.
