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. Ad hoc -hajautettu laajakaistainen langaton verkkosiirtojärjestelmä tehokkaalla MAC-kerroksen siirtoprotokollalla ja kaksikerroksisella reititysprotokollalla. All nodes are completely equal, without any infrastructure, and can quickly build a dedicated self-organizing network between mobile nodes, tarjota välitöntä mukautuvaa viestintää, niillä on erinomainen laajakaistan suorituskyky, and support the real-time transmission of multimedia information such as video coding and audio coding. Järjestelmätekniikan etuna on vahva häiriönestokyky, korkea spektritehokkuus, pitkä lähetysetäisyys, haalistumista estävä kyky, ja vahva diffraktiokyky. Se voi toteuttaa reaaliaikaisia ja korkealaatuisia langattomia kaksisuuntaisia tiedonsiirtotoimintoja monimutkaisissa ja näköyhteyttä koskevissa ympäristöissä.

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:
Yleiskatsaus:
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 -verkko: You can remark the name, tietysti, it can also be operated in the terminal state.
Spectrum scanning: Check the interference of each frequency band. Tietysti, the frequency bands of different modules are purchased, and the scanning frequency bands are different.
Map: (Tietysti, 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, jne.

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, esimerkiksi, 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.
