1. Solution Overview

WiFi HaLow Protocol Introduction

WiFi HaLow (IEEE 802.11ah) is a low-power, long-range wireless communication protocol operating in the Sub-1 GHz band (868 MHz / 915 MHz). Compared to traditional 2.4 GHz / 5 GHz WiFi, WiFi HaLow offers significant advantages in transmission range and wall-penetration capability, making it ideal for outdoor monitoring, agricultural IoT, industrial automation, and other long-range data collection scenarios.

Feature	WiFi HaLow	Traditional WiFi (2.4 GHz)
Frequency Band	Sub-1 GHz (868/915 MHz)	2.4 GHz / 5 GHz
Transmission Range	Up to 1 km+	Typically 50-100 m
Wall Penetration	Strong	Average
Power Consumption	Low	Relatively High
Use Cases	Long-range, low-power IoT	Short-range, high-speed

Morse Micro × CamThink

Morse Micro is a global leader in WiFi HaLow chip technology, headquartered in Sydney, Australia, specializing in the development and promotion of IEEE 802.11ah protocol chips. Its HaLowLink1 / HaLowLink2 series gateway products provide a plug-and-play network bridging solution for WiFi HaLow devices, seamlessly integrating HaLow networks into standard Ethernet / WiFi networks. CamThink and Morse Micro maintain close collaboration in the WiFi HaLow IoT space. The NE101 smart camera, equipped with a WiFi HaLow module, combined with the Morse Micro HaLowLink gateway, delivers a complete end-to-end solution for long-range, low-power image capture and upload.

Solution Architecture

Data Flow:

NE101 (Image Capture) → WiFi HaLow → HaLowLink Gateway → Ethernet/WiFi → MQTT Broker → Backend Platform

Stage	Description
Image Capture	NE101 captures images on schedule or trigger, generating JPEG files
HaLow Transmission	Sends data to HaLowLink gateway via Sub-1 GHz wireless link
Network Bridging	HaLowLink bridges HaLow data to Ethernet/WiFi network
MQTT Upload	NE101 publishes Base64-encoded image data to MQTT Broker
Platform Reception	Backend platform subscribes to MQTT Topic, receives and displays images

3. HaLowLink Gateway Configuration

3.1 Gateway Network Setup

Connect the HaLowLink gateway to your LAN via Ethernet cable. After powering on, access the gateway management page in a browser and verify the network connection status. For login details, refer to the HaLowLink User Guide.

3.2 Check WiFi HaLow Frequency Configuration

Navigate to Network → Wireless in the gateway management page and check the WiFi HaLow frequency settings. Select the appropriate band based on your region:

• Europe: 868 MHz
• North America: 915 MHz

Ensure the gateway and NE101 frequency settings match, otherwise the devices cannot associate.

4. NE101 WiFi HaLow Connection

4.1 Login to NE101

After powering on NE101, connect to its WiFi hotspot, then enter 192.168.1.1 in a browser to access the NE101 configuration interface.

4.2 Configure WiFi HaLow Network

Navigate to the Gateway Connection page, select a Region matching the HaLowLink gateway (e.g., US or AU), click Refresh to scan available networks, select the HaLowLink gateway AP, and enter the password to connect.

4.3 Verify Connection Status

After a successful connection, you can see NE101 listed as associated on the gateway management page:

5. MQTT Data Integration

5.1 Set Up MQTT Broker

Using AI Tool Stack as an example, create an MQTT Broker service on the platform and obtain the Broker IP address, port, and authentication credentials. You can also use NeoMind, EMQX, Mosquitto, or other platforms to set up your own MQTT Broker.

5.2 Configure NE101 MQTT Connection

Navigate to the Data Report page in the NE101 configuration interface and fill in the MQTT Broker connection parameters:

Parameter	Value	Description
Host	MQTT server IP address	Must be network-accessible from gateway
MQTT Port	1883 (or server port)	MQTT TCP port
Topic	Custom (e.g., ne101/image)	Image data publish topic
Client ID	Auto-generated or custom	Device unique identifier
QoS	QoS 0	QoS 0 recommended for image transmission
Username / Password	Per server configuration	If Broker requires authentication

After saving, NE101 will connect to the MQTT Broker via WiFi HaLow → HaLowLink gateway:

5.3 Data Format

The MQTT message payload uploaded by NE101 is in JSON format, with the image embedded as Base64 encoding:

{
  "ts": 1740640441620,
  "values": {
    "devName": "NE101 Sensing Camera",
    "devMac": "D8:3B:DA:4D:10:2C",
    "battery": 84,
    "snapType": "Button",
    "localtime": "2025-02-27 15:14:01",
    "imageSize": 74371,
    "image": "data:image/jpeg;base64,..."
  }
}

Field	Type	Description
ts	number	Timestamp (milliseconds)
devName	string	Device name
devMac	string	Device MAC address
battery	number	Battery level (%)
snapType	string	Capture type: Button, Scheduled, or PIR (sensor trigger)
localtime	string	Local time
imageSize	number	Image size (bytes)
image	string	Base64-encoded JPEG image with prefix data:image/jpeg;base64,

5.4 Verify Image Reception

Use an MQTT client (e.g., MQTTX) to subscribe to the corresponding Topic, or view received image data on the backend platform:

Base64 images can be displayed directly in web pages:

<img src="data:image/jpeg;base64,..." />
