The vehicle-mounted mesh networking equipment is individually designed for the vehicle-mounted system, and is particularly suitable for installation in communication command vehicles and large-scale mobile command vehicles. It has voice intercom function, GPS/Beidou positioning function, and also supports wifi small range coverage. It can quickly establish chain communication with other vehicle-mounted vehicles, and can also communicate with individual soldiers, handheld devices, air carriers (helicopters or drones) and surrounding base stations, and quickly establish chain communication. All nodes are in line-of-sight or non-line-of-sight environments, without the need for a central gateway, and all nodes are equal in status, that is, they can be used as terminal nodes, relay nodes or central nodes without relying on wired communication lines, and can quickly establish a wireless communication network.
The system adopts the same frequency networking, multi-hop relay, and supports any network topology, such as point-to-point, point-to-multi-point, chain relay, mesh network and hybrid network topology. Equipment working frequency: 512~582MHz, 570~590 (U section), 1240~1300MHz, 1428~1448MHz (L section). The unobstructed transmission distance can reach more than 40km, and the air-to-ground can reach more than 100km. It is especially suitable for various application scenarios such as emergency response, anti-terrorism and anti-riot, rescue and disaster relief, large-scale event protection, temporary deployment and relay transmission. It is a product specially developed for the communication ad hoc network application of ground cluster mobile vehicles. Cluster vehicles can be equipped with EST-CZ01-MESH ad hoc network vehicle-mounted radios to form a flat mesh network within a certain task area to realize the interconnection between vehicle nodes and the central base station.
♦ Non-center co-frequency networking
♦ Multi-node fast and flexible networking
♦ Arbitrary network topology
♦ Fast moving with high data bandwidth
♦ Strong anti-interference
♦ Strong ability to resist multipath
♦ Strong resistance to destruction and disaster tolerance
♦ Good security and confidentiality (also supports AES128/AES256 source encryption)
♦ All IP network interconnection (such as public network, private network, satellite communication and microwave, etc.)
♦ Support multiple services (real-time transmission of voice, image, data and positioning information)
2.1 Adopting domestically produced self-organizing intellectual property technology, dedicated SOC chip, using private communication transmission protocol, and unique synchronization code.
AES 128-bit encryption technology: After the information data is encrypted by AES, the information before encryption cannot be obtained.
2.2 Adopt a variety of encryption methods and modular design.
2.3 Centralized and distributed, all nodes have the same status, and can self-organize a network under complex conditions such as non-line-of-sight (NLOS) and high-speed movement to realize TDD transceiver two-way communication.
2.4 It supports any network topology such as point-to-point, chain, star, etc., and can realize real-time interaction of multimedia information such as multi-channel IP sub-broadband data and multi-serial data.
2.5 Multi-hop relay, each node can move quickly and randomly, and the routing can be dynamically reconfigured when the system topology changes rapidly.
2.6 Convenient deployment, flexible use, simple operation, convenient maintenance, and the all-IP design (supporting various data transparent transmission) is easy to realize the interconnection of heterogeneous systems, and is especially suitable for wireless coverage transmission and wireless narrowband data networking.
|Long Transmission Distance||using OFDM modulation, space-time coding, transceiver diversity and other technologies, the receiving sensitivity can reach -103dBm, under 10W transmission power, the ground-to-air/space-to-air line-of-sight communication can reach 100km, and the ground-to-ground line-of-sight communication can reach 50km, in non-line-of-sight environment Under the conditions, it also has better anti-multi-path interference and strong diffraction ability.|
|High Transmission Rate||adopt BPSK/QPSK/16QAM/64QAM adaptive modulation, receive diversity and other technologies, the peak rate can reach 90Mbps, suitable for large traffic multi-hop transmission, with wireless ranging function.|
|Large Network||channel resources are dynamically allocated, and the maximum actual measurement can support 40 nodes for ad hoc networking.|
|Relay||The number of data relay hops can reach 16 hops, which expands the network coverage and enhances the applicability of network applications.|
