The portable base station based on the centerless self-organizing network technology can be automatically connected to the wireless network when it is turned on. The whole network uses the same frequency point and does not rely on any public or private network for ultra-long-distance communication. It can create flexible, mobile, and robust, A non-centered self-organizing network communication system with high confidentiality.

The centerless self-organizing network communication technology innovatively realizes the characteristics of multi-hop and multi-level relay, same-frequency simulcast networking, and signal overlap and combination. It perfectly realizes the non-centered self-organizing communication network and solves the multi-point simulcasting. Communication problems caused by signal interference in retransmission and overlapping areas. The performance indicators of this technology have reached the standards of the US military.

• Ultra-long communication distance

The extremely low signal-to-noise ratio threshold (1dBm) and extremely high receiving sensitivity (-125dBm) enable the single-hop distance to exceed 1.5 times that of intercom devices with the same power on the market. The single jump distance in the ground visibility environment can reach 15-20 kilometers, and the single jump distance from high point to low point can reach 50-80 kilometers.

• No GPS timing required

Multiple base stations do not need GPS time service, and they can form a single frequency network with the same frequency when they are turned on. It is especially suitable for solving network communication problems in large buildings, tunnels and mines and other non-open-air environments.

• Flexible non-centered Ad Hoc network

The device comes with the same frequency relay function, which supports up to 8 hops of communication transmission, and extends the communication distance by 5 to 10 times. It can be networked with multiple base stations, and can also cooperate with the microsite communication self-organizing intercom group network. The networking mode is flexible, and the leaving or joining of any node does not affect the communication of the entire network.

 Secure encrypted communication

Unique communication mechanism, with AES256 encryption method and tens of thousands of block codes, realizes super encrypted communication.

• IP67 protection level

Supports IP67 protection level to ensure normal use in harsh outdoor environments.

Application Area

Fire rescue, emergency communications, public security police, armed police forces, property security, rail transit, marine vessels, petroleum and petrochemicals, electric energy, forestry scenic spots, mine caves, scientific expeditions, etc.

 

Application Mode

No central ad hoc network, any change in the network topology will not affect the coverage, and no interference in the overlapped coverage area of the base stations. The base station and walkie-talkie can be combined arbitrarily, without relying on timing, and Ad Hoc networks can be realized without base stations. Any node leaving or joining does not affect the communication of the entire network, and the network can be built after power-on, without waiting for the Ad Hoc network to converge.
