Anjielo HW-69066GF 150km Long-Range Wireless Image Transmission Module: Star and Mesh Networking Technical Overview
In the rapidly evolving drone and low-altitude economy, long-range, low-latency, and highly reliable wireless image and data transmission links have become mission-critical for power line inspection, emergency rescue, geographic surveying, and more. Traditional WiFi video links are limited by range and interference, while base-station-dependent solutions cannot cover areas without public network coverage. The HW-69066GF-XX series broadband access and data transmission module from ANJIELO SMART delivers an industrial-grade wireless transmission solution with up to 150km star-network transmission capability and 40dBm high-power output, breaking through distance limitations for industry users.
1. Product Positioning: An Independent Wireless Transmission System Without Carrier Base Stations
The HW-69066GF-XX is a broadband access and data transmission product developed based on Software Defined Radio (SDR) technology. It adopts the physical layer protocol design of the TDD-LTE 4G mobile communication standard but operates completely independently of mobile carrier base stations. This means users can rapidly build point-to-multipoint (P2MP) or Mesh self-organizing dedicated wireless links in the field, at sea, in disaster areas, and other environments without cellular coverage.
The module uses a flat system architecture, effectively reducing system latency while improving transmission capacity and anti-interference capability. Its core positioning: star networks support transmission distances up to 150km, Mesh networks support up to 50km, covering 800MHz, 1.4GHz, 1.5GHz, and 2.4GHz bands, with frequency band customization available on request.
2. Core Specifications: From Power Versions to Frequency Band Configuration
2.1 Three Power Versions and Power Supply Requirements
Depending on the isolation power requirements of the actual application scenario, the HW-69066GF-XX offers three power levels:
| Model | Supply Voltage Range | Max Power Consumption | Max Transmit Power |
|---|---|---|---|
| HW-69066GF-25 | 9-26V | 3.5W | 25dBm |
| HW-69066GF-33 | 12V ± 10% | 12W | 33dBm |
| HW-69066GF-40 | 24V ± 10% | 30W | 40dBm |
The 40dBm (10W) version draws 30W of total power and requires sufficient heat dissipation for continuous stable operation. When selecting a power version, users must consider transmission distance, antenna gain, ambient temperature rise, and power supply capability.
2.2 Flexible Frequency Band and Bandwidth Configuration
The device supports five bandwidth options: 1.4MHz, 3MHz, 5MHz, 10MHz, and 20MHz, allowing users to flexibly choose based on data throughput requirements and spectrum environment. For frequency bands, the following standard configurations are pre-installed at shipment:
- 800M band: 806-826MHz
- 1.4G band: 1427.9-1447.9MHz
- 1.5G band: 1420-1530MHz
- 2.4G band: 2401.5-2481.5MHz
Multi-band equipment can be customized according to customer needs and on-site electromagnetic environment, but users are not permitted to alter frequency band settings without authorization.
2.3 Automatic Power Control and Automatic Frequency Control
The device features Automatic Power Control (APC) : the central node transmits at maximum rated power, while the transmit power of access nodes is automatically adjusted based on signal quality. This mechanism effectively reduces overall system power consumption and electromagnetic interference while ensuring link reliability.
Automatic Frequency Control (AFC) ensures that after power-on, the device first attempts to use the frequency stored from the last power-off for networking. If that frequency is unsuitable, the device automatically searches for other available frequencies. When the central node loses synchronization, it automatically reselects a frequency; when an access node loses synchronization, it initiates a new network search process.
3. Networking Capabilities: Dual-Mode Star and Mesh Support
3.1 Star Network: 150km-Class Long-Range Transmission
The star network uses a central node + access node architecture. The central node transmits at maximum rated power, and access nodes automatically adjust their power. This mode supports 3km, 20km, 50km, 80km, and 150km software-limited distance versions, and users must select the appropriate version based on the actual application scenario.
150km transmission capability is achieved in line-of-sight conditions. Actual deployment must consider antenna height, terrain obstruction, electromagnetic interference, and other factors. Combined with high-gain directional antennas, this module can meet ultra-long-range communication needs such as cross-regional data backhaul, border surveillance, and large-scale inspection.
3.2 Mesh Network: 50km-Class Self-Organizing Network
In Mesh mode, the device supports 10km and 50km versions. Mesh networking features centerless networking, peer-to-peer nodes, and automatic optimal route selection. Nodes can function as terminals, relays, or central nodes. This mode is suitable for unmanned swarm coordination, dynamic topology changes, and multi-hop self-healing scenarios.
4. Interfaces and Indicator Lights: Key Details for Engineering Deployment
4.1 Interface Layout (PH2.0 Packaging)
With the PH2.0 interface side facing down, the interfaces from right to left are:
| Interface Position | Interface Type | Function Definition |
|---|---|---|
| Group 1 | PH2.0-4 | GND, GND, VCC, VCC — Power supply interface |
| Group 2 | PH2.0-3 | COM-R, GND, COM-T — Data transmission serial port |
| Group 3 | PH2.0-3 | debug-R, GND, debug-T — Debug serial port (non-user interface) |
| Group 4 | PH2.0-4 | RX1-, RX1+, TX1-, TX1+ — 10/100M Ethernet interface |
The RF ports are located on both sides of the indicator lights: the left side is the main antenna port (transmit and receive), and the right side is the secondary antenna port (receive only).
4.2 Indicator Light Meanings
The indicator lights from right to left are:
- Master/Slave Indicator: Always on in master mode, flashing in slave mode
- Ethernet Communication Indicator: Flashes rapidly several times during power-on self-test, then flashes according to data traffic during normal operation
- Signal Strength Indicator: Green → Yellow → Red → Off, signal strength from strong to weak; off indicates loss of connection with the host/slave
- Power Indicator: Always on indicates normal power supply
- 4.3 Critical Engineering Warnings
The transmit antenna must be connected, otherwise the device may be damaged. Not connecting the receive antenna will not damage the device but will significantly affect performance. In receive mode, the received signal strength at each port must not exceed 10dBm, otherwise the port will be permanently damaged. It is recommended that antenna spacing within the same module be greater than 0.15 meters, and antenna spacing between modules be greater than 1 meter (this applies to spacing between powered-on modules and between powered-on and unpowered modules).

7. Selection Guide
When selecting a specific model, users must clarify the following parameters: network type (star/Mesh), transmit power (25/33/40dBm), maximum distance (3/20/50/80/150km), and center frequency (816/1437/1475/2441MHz, etc.). The product naming rule is: HW-69066GF-[power]-[distance]-[frequency], for example, HW-69066GF-40-150-1437 indicates 40dBm power, 150km star networking, and 1437MHz center frequency.
For industry applications requiring ultra-long-range, high-bandwidth, and strong anti-interference capabilities, the HW-69066GF-XX series provides a complete solution from hardware to networking protocols. Its independent of carrier base stations design philosophy gives it irreplaceable value in dedicated communication scenarios in areas without public network coverage.
