Which communication technology is primarily used in RAWS for data transmission?

Radio frequency (RF) communication is primarily used in RAWS (Remote Automatic Weather Stations) for data transmission due to its ability to cover vast distances without the need for physical wiring. RF communication is well-suited to the weather station's operational requirements, allowing for flexible and mobile deployment in various terrains and conditions. The RF technology can transmit data reliably over long ranges, which is essential for the dissemination of weather data collected by RAWS to central databases for analysis and reporting.

This choice aligns with the operational needs of RAWS, which are often deployed in remote locations where other forms of connectivity, such as wired broadband or fiber optic cables, may not be available or practical. Additionally, while satellite communication is another viable option for long-distance data transmission, RF communication tends to be more cost-effective and easier to implement in the field for the specific applications of weather monitoring.
