IP mesh radio transceiver module for drone video data link UHF

IP mesh radio transceiver module is suitable for point-to-multi-point or multi-point-to-multi-point network requirements.

For example, your project requires multiple transmitters and multiple receivers. Each node can act as a relay for other nodes. Each node cannot be individually defined as a transmitter, receiver, or repeater. Each node is a transmitter, a receiver, and a repeater, such as security squads, bicycle racing, 2+ drones in the sky, 2+ receivers on the ground, and other applications.

FHSS Frequency Hopping

• We designed this wireless video and data transmission with uplink and downlink for those who need the frequency automatic hopping function.
• With frequency hopping technology (FHSS) to ensure better stable signal communication, when the current frequency signal is worse, the system will automatically change the working frequency to another frequency for a better signal.
• This bidirectional OFDM radio module can work from 566Mhz to 678MHz or from 1420Mhz to 1530MHz bandwidth. So the frequency range has 110Mhz bandwidth change or hopping. If you set the frequency bandwidth at 10 MHz, then there are 11 frequency points for hopping.

Ethernet1, Ethernet2 and Ethernet3

The three Ethernet ports on board are bridged connections, so their IP addresses are the same. The photo below shows the 4PIN signals of the Ethernet port.

Switch Port

This port is a TX transmitter / RX receiver control signal for the extra power amplifier. The maximum RF transmission power of our module is 24±1dBm two channels, We also provide the correct power amplifier to increase the RF Power to 2-watt / 5-watt /10-watt if you need a longer range than 22km.

The below diagram shows how to add a power amplifier outside extra of this IP Radio Module.

This operation is for your reference only. If you need to add an external power amplifier, it is best to tell us and we will configure it for you, or ask a professional to operate it, otherwise, the PA will be easily burned.

Signal	Electrical level	I/O	Description	mark
PA-enable1	1.8V	O	High electrical level: data transmitting, change to high electrical level at 3.19us before transmitting and to low electrical level at 0.26us after transmitting finished.	High-Tx Low-Rx

Data UART

• The data UART is RS232 as default.
• We also can change the data port from RS232 to TTL 3.3V UART before the cargo delivery.
• The baud rate of data UART can be set as 115200, 57600, 38400, 19200, 9600, 4800, 2400, and 1200.

Control UART and USB port

Only one of these two ports is valid at the same time. Control UART is valid by default shipment. Please contact us if you need to use a USB UART. You can manage our module with Web UI or AT command via control UART.

LEDs light

LED1: Power LED, red, light on normal powered.

LED2: blue, LED3: green, LED2 and LED3 indicate the wireless working status as described in the below table.

Central node	Blue LED2 light on all the time and green LED3 is not light
Access node	Green LED3 lights on all the time when the access node is connected to the central node.
	The blue LED2 indicates the access node linking signal status with the central node. When the wireless linking signal is strong, blue LED2 blinks every 30 seconds; When the wireless linking signal is middle, blue LED2 blinks every 6 seconds; When the wireless linking signal is weak, blue LED2 blinks every 1 second.

Sometimes customers may need to assemble the indicating LEDs on their housing case panel, so our board also provides a soldering hole for the three LED signals. The LED signal is described in the below table.

LED2	Wireless indicating LED	LED2-GND and LEDs-VCC
LED3		LED3-GND and LEDs-VCC

Wireless networking with the IP MESH Radio Module

• Our module supports two operating modes: Access Node and Central Node. It can be managed through Web UI or AT command via control UART.
• Our module supports features of a maximum of 63 Access Nodes connected to a Central Node. All the Nodes are in the same wireless LAN and share the whole transmission bandwidth (maximum 100Mbps throughout).
• We call downlink data from the Central Node to the Access Node, and we call uplink data from the Access Node to the Central Node.
• Uplink and downlink stream ratio can be controlled through web UI or AT command.
• When using our module for point-to-point transmitting, uplink and downlink share the whole transmission bandwidth (maximum 100Mbps throughout).
• Our module supports networking modes: Point-to-Point, Point-to-Multi-point, Relay, and Mesh (specify mesh version when ordering).

Networking Type

This module supports star networking and Mesh networking, and the prices vary greatly. Please choose the appropriate networking method according to your application.

1. Star Networking
   1. P2P: Point-to-Point Networking Type
   2. P2P Via Relay / Repeat Networking Type
   3. MP2P: Multi-Point-to-Point Networking Type
2. MP2MP: Multi-Point-to-Multi-Point Ad Hoc Mesh Networking type.
   1. In this Ad Hoc networking type, there is no central node, and each node can connect to the surrounding nodes to form a network. If one of the nodes fails or is out of range, the other nodes can re-network without being affected.
   2. Any node can be a transmitter, a receiver, or a repeater. No prior settings are required. The role of each node is dynamic and can adjust itself to changes in real-time.

FAQ

Q1: Can this mesh version be set to a P2P or P2MP model?

A1: Yes.

Q2: How many nodes does it support in one network?

A2: This star network has a maximum of 64 nodes, and the Mesh network has a maximum of 32 nods.

Q3: Can you provide options for amplifiers for ip mesh drone video data telemetry transceiver modules?

A3: We have 2 watts, 5 watts, and 10 watts PA power amplifier for this module. Each PA power amplifier we can make it at 600Mhz (566-678Mhz) or 1.4Ghz (1420-1530Mhz). There are two RF connectors for transmitting, so you’d better to add two power amplifiers for each module. In order to support frequency hopping at two bands (600Mhz and 1.4Ghz), so it is recommended that you add two power amplifiers: one is for 600Mhz, another is for 1.4Ghz. If your environment is electromagnetically clean but you need the highest bitrate, you can also use two 600Mhz or 1.4GHz amplifiers.
