Acrel AWT100-AP/WFH wireless bridge modbus Wi-Fi HaLow

Overview

AWT100-AP/WFH is a Wi-Fi data conversion module compliant with the IEEE 802.11ah standard. It can operate in both STA mode and AP mode, enabling point-to-point or point-to-multipoint wireless data transmission through networking. Among the variants, the AWT100-AP/WFHEU European version supports the frequency range of 859 MHz to 894 MHz, while the AWT100-AP/WFHNA North American version supports 902 MHz to 928 MHz. Compared with 2.4 GHz Wi-Fi, it offers longer transmission distance. This module is suitable for applications such as wireless meter reading, building automation and security, and power load monitoring.

Description of Model

List of Functions

● The physical throughput ranges from 150 kbps to 3.5 Mbps, meeting the data transmission requirements for applications from low-speed sensors to high-speed image data.

● Channel access backoff is implemented using Channel Conflict Assessment (CCA) and Carrier Sense Multiple Access with Collision Detection (CSMA/CD) mechanisms.

● The system utilizes Automatic Frequency Selection and Automatic Frequency Control to maintain optimal signal connectivity and stability

● Supports Low Power Consumption.

● Supports Relay and Roaming.

● Supports Multicast.

Typical Applications

The gateway is connected to the start-end AWT100-AP/WFH via serial port (with the AWT100-AP/WFH operating in AP mode), and the meter is connected to the terminal-end AWT100-STA/WFH via serial port (with the AWT100-AP/WFH operating in STA mode). The meter reading commands from the gateway are transparently transmitted through the wireless WiFi HaLow channel (abbreviated as WFH)established between the start-end AWT100-AP/WFH and the terminal-end AWT100-AP/WFH, then delivered via the serial port of the terminal-end AWT100-AP/WFH to the meter. The data response from the meter is returned to the gateway through the reverse path.

Technical Parameters

The test data was obtained in an open area without any barriers.
