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, long transmission distance, 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.

Software operation Instructions

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 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.

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

Channel bandwidth: 5M 10M 20M 40M

Channel: Different channels are used to purchase different products

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

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, range (MCS0 to MCS15)

Bandwidth, Modulation, Rate

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.

MCS1564QAM 5/632.5M65m130M270M

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, for example, 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.
