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, 분산, 다중 홉 릴레이, 동적 라우팅, strong invulnerability and good scalability. It uses its own routing protocol internally to complete the wireless communication between nodes through wireless multi-hop forwarding. 효율적인 MAC 계층 전송 프로토콜과 2계층 라우팅 프로토콜을 갖춘 임시 분산 광대역 무선망 전송 시스템. 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, 높은 스펙트럼 효율, 긴 전송 거리, 퇴색 방지 능력, 그리고 강한 회절 능력. 복잡하고 가시선이 없는 환경에서 실시간 고품질 무선 양방향 데이터 전송 기능을 실현할 수 있습니다..

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:

개요:

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, 물론이야, it can also be operated in the terminal state.

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

Map: (물론, 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, 기타.

Configuration section:

방법: 1. MESH node or bridge configuration

2. Wireless configuration:

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

채널 대역폭: 5M 10M 20M 40M

채널: Different channels are used to purchase different products

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

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, 범위 (MCS0 to MCS15)

대역폭, 조정, 율

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, 예를 들면, 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.
