Product Overview
This system adopts a new type of sub-broadband “wireless networking” based on point-to-point, нуқта ба бисёрнуқта, and AD-Hoc networking. As a mobile center organization network, Vcan1401 is a central, distributed, multi-hop relay, dynamic routing, strong invulnerability, and good scalability wireless broadband system. It uses its own routing protocol internally. Jump forwarding completes wireless communication between nodes. An ad hoc distributed broadband wireless network transmission system with an efficient MAC layer transmission protocol and a two-layer routing protocol. It has excellent sub-broadband performance, strong anti-interference ability of system technology, high spectrum efficiency, масофаи дароз интиқол, 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.
Facing the information communication transmission of drones, robots, and unmanned boat platforms in complex environments, we follow the design principles of generalization, modularization, and standardization to realize high-speed real-time transmission of telemetry, назорати дурдаст, and payload data from ground control stations to unmanned terminals on the water surface As well as the information collaborative interaction function between unmanned terminals, the system works continuously, stably and reliably for a long time.

Hardware description
- 1) Adopt domestic self-organized intellectual property technology, private network, private communication transmission protocol, and unique synchronization code.
- AES 128-bit encryption technology: After the information data is encrypted by AES, the information before encryption cannot be obtained;
- OFDM pilot and data position scrambling code encryption: The number of OFDM subcarriers is kept secret, the number of pilots is kept secret, and the position of the pilot is kept secret, making it impossible to obtain pilot information for channel estimation and frequency domain equalization; the change method of pilot and data position is encrypted In this way, illegal users cannot correctly distinguish pilot frequency and data.
- LDPC code word structure encryption: LDPC code word structure includes code length, information bit, and check bit; the position changes of information bit and check bit are encrypted, and illegal users cannot correctly distinguish between information bit and check bit.
- Using multiple encryption methods and modular design;
- Centralized and distributed, all nodes are equal in status, and can self-organize a network under complex conditions such as shielding non-line-of-sight (NLOS) and high-speed movement, and realize TDD two-way communication;
- Support any network topology such as point-to-point, занҷир, star, ва ѓайра, and can realize real-time interaction of multi-channel IP-based sub-broadband data, multi-serial port data, and other multimedia information;
- Multi-hop relay, each node can move randomly and quickly, and the route can be dynamically reconfigured when the system topology changes rapidly;
- Convenient deployment, flexible use, simple operation, convenient maintenance, and all-IP design (supporting various data transparent transmission) make it easy to realize the interconnection of heterogeneous systems, especially suitable for wireless coverage transmission and wireless narrowband data networking;

Саволҳои зиёд такрормешуда Бештар
Q: Why does the radio transceiver seem to power on in seconds and power off always restart?
$ A: Please check the power supply, for the 2×5-watt PA inside, the power supply should be 16-26V at 4.5A. Maybe the power supply is not enough, then always restart. (2×1-watt or 2×2-watt need 12-18V)

Q: Does your mesh two-way transceiver module support changing the frequency (канал) via the UART AT command?
$ A: ҳа, please type the below commands at the serial port tool.
AT-API+ set
wlan.radios.0.name phy0
wlan.radios.0.txpower 30 (power amplifier, 30 means 2-watts)
wlan.radios.0.маҷрои 10 (frequency bandwidth)
wlan.radios.0.канал 2 (channel)
END-AT-API
(The numbers 30, 10, ва 2 of the above command should change to what you want the number. )
Q: Does the radio support frequency hopping/ changing dynamically?
$ A: We have many models that support the frequency hopping function (FHSS). The cost is different.
The model you bought does not support frequency hopping. You can choose the frequency from the below picture. (Choose from the web page or AT commands)
Mesh Radio Transceiver Support Channel Frequency range
Q: Can I modify the less transmission power?
$ A: Албатта. When you are testing the sample on the function except for the real transmission range, it is better to change the less transmission power in the lab.

Q: How many nodes the mesh architecture can support?
$ A: Supports up to 32-node networking. Too many nodes will cause high system overhead and the network will be very unstable. одатан, a dozen nodes are recommended.
Q: Is the relay function available in this modem? if yes then how many hops possible?
$ A: Support relay function. макс 5 hops in the one line.
Q: Can we decrease the data rate to increase the range?
$ A: ҳа.
Q: Does the frequency band support 2280 МГс ба 2380 МГс?
$ A: The frequency band can not meet your demand now. Only 2310-2380Mhz is available.
Q: What about the encryption? Do you provide by default encryption details?
Q: Please show us the drawing for hole positions and size of the 2×1-watt PA model.

Q: At this mesh IP radio, the new unit will be auto-joining my networking, how can we set authorization and protect our privacy?
$ A: If you have three or four robots, those who walk in the middle will serve as relays or repeaters for those who walk in the front. If you have three or four units, they can be auto-forming networking, so setting passwords is very important.
