Brief introduction
- Our Ad hoc network communication radio station, as a mobile self-organizing network, 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.
- Some routing protocols 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, ระยะการส่งยาว, 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.

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.
Status section:
ภาพรวม:
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, แน่นอน, it can also be operated in the terminal state.
Spectrum scanning: Check the interference of each frequency band. แน่นอน, the frequency bands of different modules are purchased, and the scanning frequency bands are different.
Map: (แน่นอน, 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, ฯลฯ.
Configuration section
โหมด: 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 from each other, ตัวอย่างเช่น, 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.
