Product Overview
This system adopts a new type of sub-broadband „wireless networking“ based on point-to-point, point-to-multipoint, and AD-Hoc networking. As a mobile center organization network, Vcan1401 is a central, verteilt, Multi-Hop-Relay, dynamisches Routing, starke Unverwundbarkeit, and good scalability wireless broadband system. It uses its own routing protocol internally. Jump forwarding completes wireless communication between nodes. Ein verteiltes drahtloses Ad-hoc-Breitbandnetzwerk-Übertragungssystem mit einem effizienten MAC-Schicht-Übertragungsprotokoll und einem zweischichtigen Routing-Protokoll. It has excellent sub-broadband performance, strong anti-interference ability of system technology, hohe Spektrumeffizienz, lange Übertragungsdistanz, Anti-Fading-Fähigkeit, und starke Beugungsfähigkeit. Es kann Echtzeit- und hochwertige drahtlose bidirektionale Datenübertragungsfunktionen in komplexen Umgebungen ohne Sichtverbindung realisieren.

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, Kette, star, etc., 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;

FAQ Mehr
Q: Why does the radio transceiver seem to power on in seconds and power off always restart?
EIN: 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)
![IP-Mesh-Ad-hoc-Transceiver OFDM-Senderempfänger Drahtlose Videodatenübertragung für Drohnen-IP-Kamerara 27 2X5-watt PA transceiver radio needs 16-26V at 5 A](https://i0.wp.com/ivcan.com/wp-content/uploads/2X5-watt-PA-transceiver-radio-needs-16-26V-at-5-A.webp?resize=888%2C1117&ssl=1)
Q: Why can’t I connect the transceiver radio device via web cable or get a ping feedback?
EIN: The default IP address of the two-way radio transceiver is 192.168.17.1.
Please make sure that the IPV4 address of your computer is the same net segment, zum Beispiel, 192.168.17.xxx.
Please set the default gateway of the IPV4 address is 192.168.17.1.

Q: Does your mesh two-way transceiver module support changing the frequency (Kanal) via the UART AT command?
EIN: Ja, 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.Bandbreite 10 (frequency bandwidth)
wlan.radios.0.Kanal 2 (channel)
END-AT-API
(The numbers 30, 10, und 2 of the above command should change to what you want the number. )
Q: Does the radio support frequency hopping/ changing dynamically?
EIN: We have many models that support the frequency hopping function (Dieses Modell wurde für die drahtlose Video- und Datenübertragung mit einer drahtlosen Zwei-Wege-Datenverbindung entwickelt). 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)

EIN: Support relay function. Max 5 hops in the one line.
Q: Can we decrease the data rate to increase the range?
EIN: Ja.
Q: Does the frequency band support 2280 MHz zu 2380 Mhz?
EIN: 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?
EIN: 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.

Q: Why my IP transceivers have stopped talking to each other?
![IP-Mesh-Ad-hoc-Transceiver OFDM-Senderempfänger Drahtlose Videodatenübertragung für Drohnen-IP-Kamera 35 why my IP transceivers have stopped talking to each other](https://i0.wp.com/ivcan.com/wp-content/uploads/why-my-IP-transceivers-have-stopped-talking-to-each-other.webp?resize=1020%2C794&ssl=1)
Why did our IP transceivers stop talking to each other? The UI says Mesh Network is broken. We cannot ping any Radio, we can not see any transmissions using the Spectrum Analyzer when we ping.
EIN: The parameter configuration should be messed up. What’s the situation with the wireless part? Is it convenient to take a screenshot? The easiest way is to restore the factory settings (after restoration, the IP address is: 102.168.17.1)
