This long-range communication device, leveraging the Wi-Fi HaLow technology, is designed to provide a reliable and flexible alternative to traditional Ethernet cables in specific use cases. By utilizing the IEEE 802.11ah protocol, the HT-HD01 operates efficiently within the unlicensed SUB-1G frequency band, specifically between 902 MHz and 928 MHz. This band offers significant advantages in terms of range and penetration, making it ideal for outdoor and large-area deployments. The device supports multiple bandwidth modes—1 MHz, 2 MHz, 4 MHz, and 8 MHz—allowing for customizable data throughput depending on the specific requirements of the application. With a maximum transmit power of 21±1 dBm, it ensures robust communication over long distances while maintaining efficient power consumption. At the highest bandwidth setting of 8 MHz, the HT-HD01 can achieve data transmission speeds of up to 32.5 Mbps, making it suitable for moderate data-intensive applications such as IoT networks, remote sensing, and industrial automation systems. This combination of extended range, flexible bandwidth options, and optimized power usage makes the HT-HD01 a versatile solution for scenarios where traditional wired Ethernet connections are impractical or impossible.
