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.

Overview

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.

Nano G2 Ultra

The primary design goal of the Meshtastic Mesh Device Nano G2 Ultra is to reduce power consumption and improve battery life (Battery is NOT Included, Battery Information) by using the low power MCU NRF52840 and optimizing the power relatived designs. The typical battery life is optimized to be about 5 days. Nano G2 Ultra and Nano G1 Explorer have exactly the same Lora front-end circuit design and internal wideband Lora antenna, which supports frequencies from 815 Mhz to 940 Mhz. The wideband antenna, combined with an optimized wideband Lora RF frontend circuit, enables the Nano G2 Ultra to work with the majority of regions’ LoRa frequency bands around the world without the need for antenna changes. The design of the Nano G2 Ultra also takes into account the potential effect of the human body on its antenna performance, ensuring optimal RF performance even when carried in a pocket.
