¶ Edition Comparisons
¶ Nano Edition
The Nano Series devices are engineered to be a portable and durable solution for outdoor adventures such as hiking, piloting, skiing and more. They are designed to strike a balance between RF performance, size, ruggedness, and power efficiency, providing users with a reliable solution in various outdoor environments.
The Core Advantage of Nano Series
The Nano Series' Lora Antenna offers superior performance in various environments, including near the human body, due to its special design that minimize signal degradation and maintain efficient communication. In contrast, most other antennas currently available experience significant performance degradation when placed near the human body, as evidenced by a marked shift in resonant frequency and a substantial increase in VSWR, making them less suitable for wearable wireless devices.
