Wireless broadband SDR ad hoc network module two-way video, voice, data transparent transmission

This Wireless broadband SDR ad hoc network module is a set of ad hoc network private network communication systems specially designed for unmanned system clusters and implemented by SDR technology, which can provide transparent transmission channels for IP-based multimedia services such as video, voice, and data.

Without relying on basic communication facilities and manual configuration, a communication network can be quickly established anytime, anywhere.

This product has the characteristics of mobility, long distance, and high bandwidth. It can be used for rapid deployment of on-site networks under complex terrain conditions. It uses the characteristics of no center, multi-hop connection, and dynamic networking to enhance communication capabilities in mobile scenarios.

The product has spectrum recognition ability, strong anti-interference ability, and can support 1000 hops/second frequency hopping working mode.

The maximum communication rate is greater than 100Mbps.

1. No center anti-destroy network structure: The departure or damage of any node does not affect the operation of the overall network
2. Multiple business data: Support video, voice, location, sensor, and other IP-based data transmission
3. Multiple access methods: Support Ethernet port, and serial port, can support the transmission of control commands and video data at the same time
4. Strong anti-interference ability: Support automatic spectrum migration and frequency hopping working mode
5. Compact size: Size 133×66×33mm; Weight 400g

Specification

Modulation: QPSK/16QAM/64QAM/256QAM

Package Include

(1). One ad hoc network host

(2). 2 dedicated frequency band (1.4Ghz) antennas (depending on different models, other types of antennas are optional)

(3). Common frequency band (2.4Ghz/GPS Beidou) antenna (choose 1 from 2)

(4). Power supply/network port conversion cable 1 piece

(5). Voice/RS232 transfer cable 1 (choose 1 from 2)

(6). DC 12V adapter 1pc

Installation steps

1. Install the antenna: connect the dedicated frequency band antenna (or feeder) to the TNC head (RF1/RF2), press and rotate to fix it, and ensure that the antenna is tightened and not loose;

2. Install the power supply/network port conversion cable: connect the aviation plug (2 cores) to the main engine aviation seat, and then tighten the nut to ensure good contact.

Boot steps

1. Press the switch, turn on the power, the indicator light of the power switch is on, and the system starts self-test (It is forbidden to turn on the power without connecting the antenna, and it is forbidden to use other types of adapters）
2. After the self-inspection is completed after the neighbor node is found, the self-organizing network indicator is always on, indicating that the network is successfully established

Networking

The networking indicator light indicates the status of being in the network or being disconnected from the network. When the indicator light is on, it indicates that the network has been established. Green indicates that the network quality with neighboring nodes is good, orange indicates normal, and red indicates poor quality.

serial number	state	meaning
1	light off	offline
2	green steady	good network quality
3	Orange is always on	Average network quality
4	Steady red	poor network quality

Precautions

• Make sure the antenna is tightened;
• Keep the antenna vertical to the ground during the test;
• Do not touch the antenna with your hands or other objects during the test;
• It is not advisable to get too close to each other between devices, and they should be separated by more than 5M;
• If there are test conditions, choose a commanding height to erect one of the nodes;
• Check whether the communication link is normal through the network indicator light, and the network indicator light is always on, indicating that the link layer has been successfully connected;
• Check the environmental noise situation through the WEB interface to know whether there is co-channel interference around;
• About 5 seconds after the networking is successful, you can check the network connectivity of each node through the ping packet;
• Make sure that the cameras, PCs, and other devices that need to be connected are in the same IP address segment, and can communicate normally under the condition of a wired connection, without using the same address segment of NexFi devices (NexFi devices communicate through MAC addresses);
• Traffic flow, people flow, buildings, and trees will have varying degrees of impact on communication quality;
• When doing penetration tests inside and outside the building, the external nodes should not be too close to the building, and the distance should be more than 10M;
• If you need to achieve a longer test distance, you can adjust the bandwidth to 5Mhz through the management interface, and if you need to achieve a larger bandwidth, you can adjust it to 20Mhz;
• If it is used for video transmission, in order to avoid video freeze, you can optimize the video effect by adjusting the camera resolution, frame rate, transcoding stream, and other parameters;
• If it is used for open-air day and night testing, please take waterproof measures and ensure good heat dissipation contact.
