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

Come una rete mobile auto-organizzata, Vcan1401-Mesh supports any network topology. A differenza delle reti wireless tradizionali, it is a wireless broadband system with no center, distribuito, relè multi-hop, instradamento dinamico, strong invulnerability and good scalability. It uses its own routing protocol internally to complete the wireless communication between nodes through wireless multi-hop forwarding. Un sistema di trasmissione di rete wireless a banda larga distribuito ad hoc con un efficiente protocollo di trasmissione a livello MAC e un protocollo di routing a due livelli. All nodes are completely equal, without any infrastructure, and can quickly build a dedicated self-organizing network between mobile nodes, fornire una comunicazione adattiva istantanea, avere eccellenti prestazioni della banda larga, and support the real-time transmission of multimedia information such as video coding and audio coding. La tecnologia del sistema presenta i vantaggi di una forte capacità anti-interferenza, efficienza ad alto spettro, lunga distanza di trasmissione, capacità anti-sbiadimento, e forte capacità di diffrazione. Può realizzare funzioni di trasmissione dati bidirezionale wireless in tempo reale e di alta qualità in ambienti complessi e senza linea di vista.

The software disables DHCP by default, and the default IP address is 192.168.17.1 If you forget the address, please connect the 9th pin of the 26PIN cable to the ground to reset the parameters.

Enter the IP address of the module in the browser, and the default username and password are both admin. It takes about 20s for the module to connect to the network from power-on. The recommended browser is Chrome.

After entering, it defaults to simple mode, click expert mode to unlock more settings, suitable for professional debugging.

3. Status section:

Panoramica:

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:

Rete ad hoc: You can remark the name, Certo, it can also be operated in the terminal state.

Scansione dello spettro: Check the interference of each frequency band. Certo, the frequency bands of different modules are purchased, and the scanning frequency bands are different.

Map: (Certo, 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, eccetera.

Configuration section:

Modalità: 1. MESH node or bridge configuration

2. Wireless configuration:

2.1 Transmission power configuration, the power of different products purchased is different.

Canale di banda: 5M 10M 20M 40M

Canale: Different channels are used to purchase different products

The coverage distance (metri) needs to be filled in according to the actual situation. If it is set to 3000 metri, it is impossible to actually run to 5000 metri.

Number of Antennas 2

Fixed MCS rate: Can be set to off for automatic selection. If you want stable transmission, it is recommended to set the manual, gamma (MCS0 to MCS15)

Larghezza di banda, Modulazione, Vota

Limit MCS rate: It is recommended to enable it. After enabling it, if the fixed rate is MCS4, the software will automatically select the best modulation method from MCS0 to MCS4 during the test.

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, per esempio, 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.
