As a mobile self-organizing network, Vcan1401-Mesh supports any network topology. Unlike traditional wireless networks, it is a wireless broadband system with no center, distributed, мульти-хопты эстафета, dynamic routing, strong invulnerability and good scalability. It uses its own routing protocol internally to complete the wireless communication between nodes through wireless multi-hop forwarding. An ad hoc distributed broadband wireless network transmission system with an efficient MAC layer transmission protocol and a two-layer routing protocol. All nodes are completely equal, without any infrastructure, and can quickly build a dedicated self-organizing network between mobile nodes, provide instant adaptive communication, have excellent broadband performance, and support the real-time transmission of multimedia information such as video coding and audio coding. The system technology has the advantages of strong anti-interference ability, high spectrum efficiency, ұзақ тарату қашықтығы, anti-fading ability, and strong diffraction ability.

From MCS0 to MCS7, two wireless ports send the same data in order to improve stability during the movement.

From MCS8 to MCS15, the two wireless ports send different data, which can make the rate X2

If it is in a mobile state, it is recommended to use BPSK or QPSK to transmit data. 16QAM and 64QAM are suitable for use with fixed transmission.

If MCS8 to MCS15 is used, it is recommended that the antennas of the two ports be 90 degrees to each other, Мысалға, one is vertical and the other is horizontal.

If drones are used, MCS0 to MCS2 is recommended.

The greater the bandwidth, the lower the sensitivity. The same goes for modulation.
