In a conventional GNSS RTK survey, the data transfer from the base to the rover can be made either through a ______ or a telephone link.

Explanation:
Real-time corrections from the base to the rover must travel quickly and reliably. A radio link provides a wireless, field-friendly channel with low latency, which is essential for updating the rover's position in real time during RTK surveys. Television, facsimile, and telegraph are not suitable for transmitting continuous GNSS correction data in real time—they’re designed for other purposes or are far too slow. The idea of using a telephone link is also possible in some setups, but in conventional field practice the radio link is the standard choice due to its practicality and real-time performance.
