Long-Range 11ah Wi-Fi HaLow Connectivity

The EW-7720GDH is an IEEE 802.11ah Wi-Fi HaLow USB dongle designed for long-range and low-power wireless communication. Operating in the sub-1GHz 900 MHz spectrum, it delivers superior signal penetration and wide-area coverage compared to traditional Wi-Fi. With transmission distances of up to 1.5 km, it is ideal for smart city infrastructure such as street facilities, public surveillance, parking systems, and environmental sensors deployed across wide outdoor areas.
 

High-Capacity, Scalable Networking for IoT Deployments

Supporting up to 8,191 concurrent nodes, the EW-7720GDH is well suited for large-scale IoT and smart city applications. This high device capacity enables centralized monitoring and data collection across extensive networks, reducing infrastructure complexity and deployment costs while maintaining reliable connectivity for sensors, meters, cameras, and industrial devices.
 

Balanced Speed for Data-Intensive Applications

With data rates of up to 43.33 Mbps, the EW-7720GDH provides a strong balance between range and throughput. Unlike LPWAN technologies, it supports bandwidth-demanding applications such as long-distance IP cameras and real-time data transmission, making it suitable for smart surveillance, industrial monitoring, and intelligent infrastructure in smart city and IoT applications.
 

Flexible Antenna Design for Extended Coverage

Equipped with a R-SMA external antenna connector, the EW-7720GDH allows flexible antenna selection to meet different deployment needs. When paired with a high-gain antenna, transmission distances can be extended beyond 10 km, enabling customized long-range configurations for outdoor, rural, and industrial environments.
 

USB Integration for Rapid Deployment

The USB 2.0 interface enables easy integration with PCs and embedded systems. With Windows and Linux driver support, the EW-7720GDH can quickly add Wi-Fi HaLow capability to routers, gateways, IPCAMs, and industrial devices, accelerating deployment without redesigning existing hardware platforms.
 

Industrial-Grade Reliability for Harsh Conditions

Designed for demanding environments, the EW-7720GDH supports a wide operating temperature range from –20 °C to 60 °C. Its compact USB dongle form factor and robust wireless performance make it a reliable choice for smart city, IIoT, and outdoor IoT applications requiring stable, long-term operation.
