Mesh Ad hoc network communication module

1. Brief introduction of ad hoc network communication module

Fel rhwydwaith hunan-drefnu symudol, Vcan1401-Mesh supports any network topology. Yn wahanol i rwydweithiau diwifr traddodiadol, it is a wireless broadband system with no center, dosbarthu, ras gyfnewid aml-hop, llwybro deinamig, strong invulnerability and good scalability. It uses its own routing protocol internally to complete the wireless communication between nodes through wireless multi-hop forwarding. System drosglwyddo rhwydwaith diwifr band eang dosbarthedig ad hoc gyda phrotocol trawsyrru haen MAC effeithlon a phrotocol llwybro dwy haen. All nodes are completely equal, without any infrastructure, and can quickly build a dedicated self-organizing network between mobile nodes, darparu cyfathrebu addasol ar unwaith, â pherfformiad band eang rhagorol, and support the real-time transmission of multimedia information such as video coding and audio coding. Mae gan dechnoleg y system fanteision gallu gwrth-ymyrraeth cryf, effeithlonrwydd sbectrwm uchel, pellter trosglwyddo hir, gallu gwrth-pylu, a gallu diffreithiant cryf. Gall wireddu swyddogaethau trosglwyddo data dwy ffordd di-wifr amser real ac o ansawdd uchel mewn amgylcheddau cymhleth a di-llinell olwg.

Support 5M, 10M, and 20M bandwidth, real-time graphical interface display, real-time map indication, etc.

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:

Trosolwg:

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:

Rhwydwaith ad hoc: You can remark the name, wrth gwrs, it can also be operated in the terminal state.

Sganio sbectrwm: Check the interference of each frequency band. Wrth gwrs, the frequency bands of different modules are purchased, and the scanning frequency bands are different.

Map: (Wrth gwrs, 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, etc.

Configuration section:

modd: 1. MESH node or bridge configuration

2. Wireless configuration:

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

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, er enghraifft, 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.
