Operate guide for Vcan1401-Mesh Ad hoc network communication module

Mesh Ad hoc network communication module

1. Brief introduction of ad hoc network communication module

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, multi-hop relay, 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, நீண்ட பரிமாற்ற தூரம், anti-fading ability, and strong diffraction ability. It can realize real-time and high-quality wireless two-way data transmission functions in complex and non-line-of-sight environments.

Topology map: (automatic refresh is turned off by default to save bandwidth, you can check automatic refresh)

Check only the display path, you can know the direct jump point relationship of each module

Check the details to judge the data connection status of each module. These are displayed dynamically in real time

Click Details: You can know the specific situation of each module directly:

Terminal state:

Ad hoc network: You can remark the name, நிச்சயமாக, it can also be operated in the terminal state.

Spectrum scanning: Check the interference of each frequency band. நிச்சயமாக, the frequency bands of different modules are purchased, and the scanning frequency bands are different.

Map: (நிச்சயமாக, to know the location information of each terminal, GNSS modules such as GPS or Beidou need to be installed)

Support tile maps, image maps, network maps, போன்றவை.

Configuration section:

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, உதாரணத்திற்கு, 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.
