NPX900 - Ultracompact, 900 MHz (750-950) with 20dBm of RF power for 2KM+ LOS and 300m+ NLOS with multiple ethernet and transparent TTL ports, in a 55x42mm package, consuming only 1.5W

NPX 900

is a wireless data solution that is both compact and cost-effective. It is particularly well-suited for use in small ground robots, aerial drones, and surveillance applications where space is limited. The device offers a range of connectivity options and operates at ultra-low power, making it suitable for use in challenging environments. NPX 900 uses UHF TVWS bands, which provide a longer range than other technologies such as 2.4GHz and 5GHz. With 20dBm (100mW) of RF output and support for 1/2/4/8MHz channel widths, as well as an optional short guard interval (SGI), it can achieve PHY throughput of 150 Kbps to 15 Mbps for various applications. Additionally, the device offers a transparent ethernet connection and 3.3V transparent TTL data for easy integration.

Wireless range can be easily extended to 20km+ with our lineup of compact RF amplifiers.

Why 900 MHz vs 2400 or 5Ghz?

The range of a wireless signal, such as those used in Wi-Fi networks, can be affected by several factors, including the frequency at which it operates. In general, lower frequency signals tend to travel farther than higher frequency signals.

The main reason for this is that lower frequency signals have longer wavelengths. Longer wavelengths are less prone to attenuation or weakening as they encounter obstacles like walls, furniture, or other objects. They can also diffract or bend around obstacles more effectively, allowing them to reach greater distances.
In contrast, higher frequency signals, like those in the 2400 MHz range, have shorter wavelengths. These shorter wavelengths are more easily absorbed and scattered by obstacles, resulting in a shorter effective range. They are also less likely to bend around objects, which further limits their reach.
